Chapter 1 Uplink-Set
1.1 Functional outline of uplink-set
The uplink-set has 1 or multiple collections of uplink port.
The uplink-set is an element which comprises of groups such as port group, service LAN and service
VLAN and uplink-set connects the customer's LAN to server blade.
The example when uplink-set "Group-A" and "Group-B" are composed in uplink port is shown below.
When the uplink-set is configured, this product is configured with linkaggregation internally.
The uplink-set "Group-A" of the above-mentioned example is a state in which linkaggregation is
configured in uplink port 0/19, 0/20 and 0/21. The uplink-set "Group-B" is a state in which
linkaggregation is configured in 0/26.
1.2 Default configuration of uplink-set
By default, uplink-set, named “default”, is defined.

1.3 LACP settings
When LACP (Link Aggregation Control Protocol) is enabled by uplink-set, Linkaggregation in the
uplink-set is starting to send the LACPPDU without any effects by its peer, and then it forms the
linkaggregation after negotiating peer switch. Therefore, the link is not up if there are some
mis-configuration or mis-connection, only the interfaces that are set correctly can be linkup.
1.4 IGMP snooping/MLD snooping settings
When IGMP snooping/MLD snooping is enabled in the uplink-set, IGMP snooping becomes enabled in
the port group, VLAN group, service LAN, service VLAN, that uses this uplink-set. Also, when the
uplink-set is shared among multiple groups, the IGMP snooping/MLD snooping is enabled in all the
groups which are shared.
When multiple groups are configured to IBP, if registration of multicast is done in the group in which
IGMP snooping/MLD snooping is enabled, For the group in which the IGMP snooping/MLD snooping is
disabled, operate as if IGMP snooping/MLD snooping is enabled for the frame which has the same
VLAN ID and, same Multicast address as the registered multicast. When same VLAN ID and same
multicast address is used by multiple groups, the IGMP snooping/MLD snooping settings should be
same for all the using groups.
1.5 CEE settings
When CEE is set to enable in the uplink-set, CEE function becomes enabled in the port group that uses
this uplink-set. When CEE is enabled in port group CEE becomes enabled in all the port groups which
are assigned to that port group. Moreover, the CEE function is not supported in VLAN group, service
LAN, and service VLAN.
1.6 Points to note
Since the up-link set configures linkaggregation, when uplink-set and corresponding device is
connected, connect the uplink port that is attached to the same uplink-set with the same
corresponding device.

1.7 Creation/ deletion of uplink-set
When uplink set is created, any uplink ports are not included in that uplink-set. When the uplink-set is
deleted in the state where uplink port is included in the uplink-set, the included uplink port does not
belong to any of the uplink-set and changes to Disable state. The uplink-set named "default" is created
by default and this must exist and cannot be deleted.
Maximum number of uplink-set that can be defined is 18.
1.8 Addition/ deletion of uplink port
Only uplink port can be added to the uplink-set. Downlink port cannot be added. Maximum number of
uplink ports that can be added is 8.
An uplink port can be assigned to the any uplink-set. However, uplink port that is already included in
the uplink-set cannot be assigned to any other uplink-set. When uplink port which is already included
in the uplink-set is to be assigned to the other uplink set, it should be deleted from the uplink set
where it already exists and should be assigned to the other created uplink-set.

Chapter 2 Port backup
2.1 Functional outline of port backup
Port backup divides uplink ports, assigned to the uplink-set, into 2 groups. One port out of 2 groups is
considered as active port (Active linkaggregation) and other one is considered as backup port (Backup
linkaggregation) and either group can be activated (Operated) as the other can be backup port at the
same time. When the port backup function is used, if active ports in the uplink-set are all linked down,
the effect of network error can be brought under control at once by switching to the group of stand-by
backup port. While active port is in operation, backup port is in the stand-by mode and cannot
communicate and the link status of it is ‘Linked up’.
Link down all the active ports and switching to the backup ports is called as Failover. After that link up
the active ports and switching from backup ports to active ports is called as Failback.
When port backup is enabled, Failback is executed automatically and ‘No Failback’ cannot be set.
2.2 Enable/ Disable port backup
By default port backup of uplink-set is ‘disabled’. When port backup is to be used in the uplink-set,
after specifying the name of uplink-set, port backup is enabled.
When active ports and backup ports are defined in the uplink-set, the operation that disables the
function of port backup is used only to disable the port back function. It cannot be used to switch over
from backup port to active port. Concretely, when uplink-set is in the state where it is configured by
active linkaggregation and backup linkaggregation, the backup function cannot be operated and
backup linkaggregation can be used as normal linkaggregation.

2.3 Changing Failback time
After executing Failover by port backup, Failback is executed when active ports are linked up again.
Time starting from link up the active ports till Failback is called as Failback time. Specify the uplink-set
when you change Failback time.
2.4 Changes of Change Notify
When operation port is switched due to Failover/Failback by port backup, set whether to send the MAC
learning frame for external switch that is connected to the side, which has newly become as an
operation port.
Following configuration is assumed for the sending of MAC learning frame.
Since operation port is ‘Active’ when linked up to both active port and backup port; the frame is
broadcasted like red arrow (→) as shown in the following figure. In addition, MAC of Blade 1, 2, 3 is
studied from switch A, Switch B. At this time, link down should be generated and operation port
should switch to backup side and the frame should be broadcasted like blue arrow (→). Unless the
frame is sent from the Blade side, the MAC learning table of switch B is not updated. Hence, the frame
from switch C is broadcasted and discarded in switch A. Here, learning table of switch B can be
changed after generating the ‘switching’ by enabling this function. In addition, broadcasting
destination of the frame can be switched to the backup side.
The frame for MAC learning is sent by using and broadcasting LLC(TEST) frame towards the adjacent
switches.

2.5 Addition/ deletion of backup port
When uplink port is added to the uplink-set, uplink port automatically becomes active irrespective of
port backup being enabled or disabled.
Specify a port to add uplink port which is an active port to the backup port and set it to backup port.
However, all the uplink ports in the uplink-set cannot be set into the backup port.
Deletion of backup port changes the uplink port from backup port to active port.
2.6 Default configurations
When uplink-set is newly created, by default, the port backup is set to ‘disabled’ and all the uplink
ports assigned to the uplink set are active ports. Moreover, Failback time is set to 60 seconds, when
port backup is enabled in the uplink-set port and ‘Send learning frame’ is set for ‘Change Notify’.
2.7 Precautions
When port backup is enabled there is no restriction on the frequency of the failover and failback.
Active port and the backup port are switched according to the situation.
At the time of device start up and cable connection, and when the backup port is linked up previously,
the backup port operates temporarily, however, the operation port switches to an active port after the
failback time passes.

Chapter 3 Linkstate
3.1 Functional outline of linkstate
The linkstate is a function to link down all the downlink ports of the group (port group, VLAN group,
service LAN, and service VLAN) which includes the uplink-set, when the port in the uplink-set are all
linked down.
Because Downlink port which is interlocking with link down of uplink port changes to Offline status
and then link down, OS in server blade detects the link down with NIC on the blade and OS can switch
the communication to other switch blade. Therefore, this function is useful when 2 switch blades are
installed in the blade server.

Similarly, when the link down is generated in the Uplink Set 2, downlink port 0/6 - 0/8 changes to
Offline status.
B VLAN group configuration example
When the VLAN group is configured like the figure given below, downlink port 0/1 - 0/5 of VLAN group
which includes relevant uplink-set changes to Offline status if the Uplink Set 1 is linked down. Similarly,
when the Uplink Set 2 is linked down, downlink port 0/6 - 0/10 changes to Offline status.

3.3 Enable/ disable linkstate function
When the setting of linkstate is changed, uplink-set is specified. When the link state is set to enable,
the downlink port interlocks with the link state of uplink-set. It does not interlock when set to
disabled.
3.4 About interlocking with the port backup
It is possible to use by interlocking the linkstate function with port backup by uplink set. In case where
both port backup and link state are set to enable by uplink-set, linkdown is done by downlink port by
linkstate function when active linkaggregation and backup linkaggregation of uplink-set related to
the downlink port are linked down together.
3.5 Default setting
When the uplink-set is newly created, linkstate is enabled in default.
3.6 Precautions
When the port backup and linkstate are set to enable at the same time, switching from the linkstate
to the backup port is previously executed. After that, backup port of port backup is linked down.
Linkdown of downlink port is done after active port and backup port are linked down together.
The downlink port where link down was done by linkstate function automatically changes to Enable
status and is linked up, if the uplink-set is linked up again.
When the downlink port is assigned to multiple groups such as port group and service LAN, downlink
port become a group and uplink-set become multiple. In this case, if either of uplink-set is linked
down, downlink port changes to Offline status. The uplink-set that becomes a group are all linked up
in the Enable status.
When LACP is enabled in uplink-set and when it is connected with the switch wherein LACP does not
operate, downlink port changes to Offline status by the linkstate function even though it is in linked
up state.

Chapter 4 Port group
4.1 Functional outline of port group
Port group is a collection of ports divided logically in the switchblade.
The port group is formed from group of multiple downlink ports and single uplink-set.
In the port group, communication is possible between downlink port and uplink set assigned to group.
The port in the port group cannot communicate between other (VLAN) port groups.
The above figure is an example in which 3 port groups are defined which are divided into 3 in the
switchblade. When there is communication only between the serverblade, the group configuration
which does not include the uplink-set like "Port Group 3" can be created. The group wherein such an
uplink-set is not included can be enabled as port group. It cannot be enabled in VLAN group, service
LAN and service VLAN.

4.2 Frame handling of port group
The port group can transmit and receive untagged frame and tagged frame.
When untagged frame is received by input port, it is transmitted by output port in untagged frame.
When tagged frame is received by the input port, it is transmitted in tagged frame tagged in VLAN ID
of the received frame.

4.3 Default configuration of port group
The status in the default is that, the uplink set "default” has all the uplink ports and the port group
"default" is configured by all downlink ports.
4.4 Precautions for port group
When multiple port groups are configured, the frame of {vid, mac} is received in the port group of one
side. If the frame for {vid, mac} is to be relayed in other port group, when relayed to port of another
port group, as in the operational outline in the following figure, the frame is cancelled. Since the port
group is different. Therefore in each port group the usable {vid, mac} should be unique in the entire
device
4.5 Precautions for port group
VLAN ID=1006-1023 is assigned to the Default VLAN ID of the port assigned to the port group
according to the definition of the port group. As for the port assigned to the port group "default", VLAN
ID=1006 is assigned and VLAN ID=1007-1023 is assigned in order in which the definition of port group
is added.

4.6 Creation/deletion of port group
When port group is created, downlink port and uplink-set is not included in the concerned port group.
When the port group communicates only between downlink ports, uplink-set is not required, therefore
it need not be assigned. When uplink-set is assigned, specification is executed at the time of creating
port group or after creating it. However, when uplink-set is already assigned to port group, VLAN group,
and service LAN, excluding service VLAN, that uplink-set cannot be specified.
When port group is deleted, the assigned down link port and uplink-set are released from the port
group.
Though it is possible to change from the uplink-set that has been already assigned to other uplink-set,
at the time of releasing uplink-set from the port, only uplink-set cannot be released. When uplink port
is released from the port group, the port group needs to be deleted once. Also, port group "default"
that is created by default, should exist and it cannot be deleted. At the time of releasing uplink set
from the port, only uplink-set cannot be released.
The maximum number of port groups that can be defined is 18.
4.7 Addition/deletion of down link port
When down-link port is added to the port group, the downlink port not assigned to other (VLAN) port
group is specified. When the downlink port that has already been assigned to other (VLAN) port group,
is added to a different port group, it is added after once deleting the downlink port from the (VLAN)
port group.
(The operation differs from up-link set.)

Chapter 5 VLAN group
5.1 Functional outline of VLAN group
Port group cannot share the uplink-set in the port group where as VLAN group can share uplink-set in
the VLAN group.
To share the uplink-set, VLAN ID is assigned into each VLAN group and frame on uplink-set to be
shared are tagged and identified by the VLAN ID of VLAN group. VLAN ID assigned in VLAN group must
be unique in the VALN group wherein uplink-set is to be shared. However, in this product unique VLAN
ID is not required.
The assigned VLAN group is not shared between VLAN groups and it is single in the down-link port.
Moreover, in the port group, uplink-set, downlink ports are not shared together.
In the above figure, the example shows 5 VLAN groups that are defined in this product. VLAN Group 1,
2, 3 share same uplink-set and in the same way, VLAN group 4, 5 share same uplink-set.

5.2 Functional outline of VLAN group (Native VLAN option)
When a frame is received in the uplink-set of VLAN group, if it is an untagged frame, it cannot be
identified that it is from which VLAN group. Therefore, a tagged frame should be transmitted. If
untagged frame is arrived in the uplink-set, VLAN group cannot be identified and that frame is
discarded.
Native VLAN option modifies this ‘Discard’ operation and assigns VLAN group to the untagged frame.
Native VLAN option can be defined in 1 VLAN group out of the VLAN groups where same uplink-set is
shared. When native VLAN option is set, untagged packet in the uplink port is not discarded and
handled as frame of assigned VLAN group and transmitted into that particular VLAN group.
However, when native VLAN option is set, frames tagged by VLAN ID of assigned VLAN group are
discarded.
In the following example, native VLAN option is set in VLAN group2. In this case, untagged frames
arrived in Uplink Set1 are transmitted to VLAN Group 2 as the frames of VLAN Group2. Since Native
VAN is not set in VLAN Group 4, 5, tagged frames of Uplink Set 2 are discarded.

5.3 Frame handling of VLAN group
In the VLAN group, tagged frames are sent and received to the uplink side and untagged frames are
sent and received in the downlink side.
In communication from the uplink to downlink, tagged frame attached with the tag of VLAN ID
defined in VLAN group that includes that uplink-set from the input port is received. If untagged frames
are received, those frames are discarded. Received frame is transmitted into the VLAN group that
matches with the VLAN ID of the frame and sent to output port as untagged frame.

5.4 Frame handling of VLAN group (Native VLAN option)
Native VLAN option modifies the operation when untagged frames are received in uplink port. When
native VLAN option settings are enabled, untagged frames discarded in the uplink port till now are
transmitted into the VLAN group. However, in the VLAN group wherein native VLAN option is enabled,
tagged frames transferred till now are discarded.
Native VLAN option modifies the operation of untagged frames in the uplink port and for this purpose
it can be set to ‘enable’ for any 1 VLAN group out of VLAN groups wherein uplink set is shared.

5.6 Precautions
When native VLAN option is defined, in the uplink-set of VLAN group wherein native VLAN is set,
frames tagged by the VALN ID of such VLAN group are discarded. Frames of VLAN group wherein native
VLAN option is set are communicated as untagged frames.
When multiple VLAN groups that have same VLAN ID is configured and if same MAC address is used in
each VLAN group, the frames may get discarded. (Refer precautions of port group)

5.7 Creation/ deletion of VLAN group
In the state of ‘created VLAN group’, downlink port is not included in that particular VLAN group. When
creating a VLAN group, uplink-set must be specified and ‘uplink-set not included’ configuration cannot
be defined. When uplink-set is not required, use the port group.
At the time of creation, uplink-set to be specified can be assigned beforehand to the VLAN group and
service VLAN. However, uplink-set already assigned in the port group and service LAN cannot be
specified.
Moreover, use different VLAN ID in the VLAN group that shares the same uplink-set.
When VLAN group is deleted, assigned downlink port and uplink set are released from the VLAN group.
After creating a VLAN group, already assigned uplink-set cannot be changed to different uplink-set.
When uplink-set is to be changed, VLAN group is deleted once.
18 VLAN groups can be defined
Creation/deletion operation of VLAN group does not block communication of other VLAN groups that
use same uplink-set or other uplink-set.
5.8 Addition/ deletion of downlink port
When downlink port is added to the VLAN group, specify the downlink port that is not assigned to the
other (VLAN) port group. When the downlink port already assigned to the other (VLAN) port group is
added to another VLAN group, the downlink port is added after deleting once from the (VLAN) port
group.
5.9 Setting/ deletion of native VLAN option
Since VLAN group is assigned in untagged frames in the uplink-set, native VLAN option can be set in
one of the VLAN groups that share the same uplink group.
Cancellation of native VLAN option changes the process in the uplink-set of VLAN group wherein native
VLAN option is set. (Returns to default operations). Definition of VLAN group is not deleted.

Chapter 6 Service LAN
6.1 Functional Outline of service LAN
Service LAN is a group definition for the normal communication broadcasted from the groups defined
in the port groups or VLAN groups. Other than that, it is a group definition for communication to
manage the server. Service LAN is configured either in the dedicated uplink-set on the uplink side or
port group on the downlink side or into the port belonging to the VLAN group.
Service LAN is defined in downlink port by overlapping with the other group. Therefore, frame on
downlink side is a frame tagged with VLAN ID for service LAN to distinguish it from other group. On the
other hand, frame on uplink-set side, is an untagged frame as service LAN dedicated use. VLAN ID
used in service LAN must be unique in the VLAN group that shares defined service LAN, service VLAN
and downlink.

6.2 Frame handling of service LAN
Service LAN executes sending and receiving of untagged frames on uplink side and tagged frames on
downlink side. Uplink side uses uplink-set of service LAN dedicated and downlink is shared with the
group such as port group and VLAN group. Therefore, in the port group and VLAN group wherein
service LAN and downlink are shared, frames tagged with the VLAN ID of service LAN in other than the
port assigned into the service LAN are not used and discarded.
In the communication from uplink to downlink, untagged frames are received from the input port. If
tagged frames are received, those frames are discarded. The received frames are transmitted into
service LAN and are sent as tagged frames assigned to the service LAN in the output port.

service LAN is processed as frames of other said group definitions. Received frames are transmitted in
the service LAN. In output port, in communication from downlink to uplink port untagged frames are
sent. In the communication from downlink to downlink, tagged frames are sent.

6.3 Default configuration
Service LAN is not defined in default.
6.4 Precautions
When the tagged frame is received, the uplink-set of service LAN cancels that frame to communicate
with untagged frame.
The isolate setting of service LAN is disabled and the port assigned to service LAN has multiple port
groups. As for the definition which includes the VLAN group, the performance is limited in order to
execute the relay processing of the switch with software.
6.5 Creation/ deletion of service LAN
When service LAN is created, VLAN ID of tagged frame which is transmitted and received by the
downlink port and the dedicated application set are specified. The downlink port is not assigned to the
service LAN in the state in which service LAN is created. VLAN ID specified at the time of creation
cannot use the ID assigned to other service LAN and service LAN.
When service LAN is deleted, assigned uplink-set is released. When the downlink port is assigned to
the group other than service LAN, it remains in that group. And, when it does not remain in the group
other than service LAN, it changes to Disabled status. After service LAN is defined, VLAN ID and the
uplink-set cannot be changed. In case it is changed, it is necessary to delete the service LAN once and
redefine.
The maximum number of definitions of the service LAN is 17.
6.6 Addition/deletion of downlink port
When the downlink port is assigned to service LAN, the downlink port is accepted, even if it is already
included in the port group, VLAN group, service LAN and service VLAN.
When the downlink port is to be deleted from the service LAN, specify the service LAN from which it is
to be deleted and then delete it.

Chapter 7 Service VLAN
7.1 Functional outline of service VLAN
Same as in service LAN, service VLAN is a group definition to carry out the communication by which
server blade is managed and it is possible to define the server VLAN by sharing the uplink-set with
port group or VLAN group against the service LAN which needs the dedicated uplink-set.
Service VLAN is defined by overlapping with other groups by the downlink port. Therefore, in order to
distinguish from other groups, the frame on the downlink port side is a tag frame tagged with VLAN ID
for service VLAN. It is a tagged frame because it overlaps with the port group or the VLAN group for the
uplink port side. VLAN ID which is to be used for service VLAN should be unique between VLAN groups
which share predefined service LAN, service VLAN and uplink-set/downlink.
First of all, it is an example when downlink port of service VLAN is shared with downlink port of port
group and downlink port of VLAN group is shown.
After that, it is an example when uplink-set of service VLAN is shared with uplink-set of port group and
uplink-set of VLAN group respectively is shown. As for this configuration, in order to carry out the relay
processing with software, the number of definitions and performance are limited (Refer to the
precautions given below).

7.2 Frame handling of service VLAN
Service VLAN is transmitted and received with the tagged frame on the uplink side and also on the
downlink side. Uplink-set shared with port group or VLAN group is used on both uplink side and
downlink side. Therefore, the tag frame tagged in VLAN ID of the service VLAN excluding the port
assigned to service VLAN cannot be used and is cancelled in port group and VLAN group shared with
service VLAN.
The tag frame tagged in VLAN ID assigned to service VLAN by the input port is received from the uplink
in the downlink communication. The tag frame tagged in VLAN ID other than untagged frame and
service VLAN is processed as a frame of another relevant group definition. The received frame is
forwarded in service VLAN and is transmitted in output port with the tag frame tagged in VLAN ID
assigned to service VLAN.

7.3 Default configuration
Service VLAN is not defined in the default.
7.4 Precautions
Uplink- set of service is shared with VLAN Port group or VLAN group and port assigned to service VLAN
limits the efficiency required for execution of relay process in the switch by software for the definition
which includes multiple port group and VLAN group. When the performance is necessary, enable the
‘isolate’ settings by using the service LAN or by using the independent uplink-set which is not assigned
to the port group and VLAN group in the uplink set of service VLAN.
7.5 Creation/deletion of service VLAN
At the time of creation of service VLAN, uplink-set, the VLAN ID of the tagged frame sent received by
the downlink port and uplink-set is specified. The down-link port is not assigned to the service VLAN
when the service VLAN is created. The VLAN ID specified at the time of creation, does not use the ID
already assigned to the service LAN and service VLAN.
The assigned uplink-set is released when service VLAN is deleted. When the downlink port is assigned
to a group other than service VLAN, it is always included in that group. It changes to ‘Disabled’ when
not included in group other than service VLAN. After defining the service VLAN, VLAN ID, uplink-set
cannot be changed.
If it is to be changed, delete the service VLAN once and redefine it.
The maximum number of service VLAN that can be defined is 1000.
7.6 Addition/ deletion of down link port
When downlink port is assigned to the service VLAN, the down-link port can already be included in
port group, VLAN group, service LAN, and service VLAN.
When the downlink port is to be deleted from the service VLAN, Specify the service VLAN to be deleted
and carry out deletion.

Chapter 8 Spanning tree function
When using uplink-port in the IBP, it should be handled as 1 port in the uplink-set, and loop
configuration is not generated so that only 1 uplink-set should be included in the port group/VLAN
group. Therefore, the spanning tree function is not supported.

Linkaggregation or the mirror function can be set in individual ports in IBP.
The port which can be set in linkaggregation and the mirror port are shown below.

However, the uplink port and the downlink port cannot be set in the same group for linkaggregation.
In addition, when linkaggregation is configured at the downlink port, it should be assigned to the
same port group or VLAN group.
Also, various settings of the linkaggregation (mode, algorithm) can be changed only in
linkaggregation individually set in the port. Settings cannot be changed in linkaggregation used in

However, operation is executed as set by the isolate option for service LAN and service VLAN that
become software relay targets, and it is operated independently of the settings of communication
between downlink ports in port group and VLAN group which share the port.
When the isolate setting of the port group is Disable like the example given below, the
communication normally becomes possible between Server 1 and Server 2 in Group 1 as for the frame
of service LAN.

Port Group (isolate Disable)

Since service LAN becomes software relay targets due to the addition of downlink port of Group 2 in
service LAN, frame of service LAN cannot carry out communication between server 1 and server 2
which is influenced by isolate setting of Port Group.
In Group1, the communication between
the downlink ports of Service1 and
Service2 becomes possible.

Chapter 13 IGMP Snooping operation When multiple groups are configured in IBP and IGMP Snooping enabled/disabled groups are mixed; if
multicast is registered in the group where IGMP Snooping is enabled, operate the frames that have
same VLAN ID and same multicast address as to that multicast registered in the group where IGMP
Snooping is disabled as if IGMP Snooping is enabled. When using same VLAN ID and same multicast
address in multiple groups, set same IGMP Snooping settings in all the groups to be used. An example
is shown below.
Operation when IGMP Snooping is set to enabled in all the groups wherein same {VLAN ID, MAC} is
used.

Chapter 14 Authentication function
IEEE 802.1x authentication, MAC address authentication functions are supported in the IBP. Port
that can be specified in the authenticated port is only downlink port. Moreover, ports only of
service LAN and service VLAN wherein port groups, VLAN groups are not assigned cannot use
Untag frames, therefore, authentication function is disabled. After the successful authentication
by the authentication function, both Untag, Tag frames can be used. When RADIUS server is
installed on the outer side and remote authentication is executed, VLAN ID notified by the
RADIUS server is discarded.
Setting items Settings Remarks
Authentication function IEEE802.1x authentication
MAC address authentication
Authenticated port Downlink port Settings disabled for
