20 LINE-UP FOR ETHERNET TRAFFIC

20.1 GENERAL

This paragraph deals with line-up of LIM Ethernet module with details of WebLCT program related only to

Ethernet application.

Assuming that the radio link is already in service, with correct frequency, output power and correct antenna

alignment, the line up procedure for two different kinds of connection set up of a radio link ALplus2,

equipped with LIM module with Ethernet ports, is hereafter described:

Local Lan-1 port to remote Lan-1 port connection Lan per port, see Fig.97

from 3 ports to 3 ports connections and segregated traffic for Untagged Traffic, see Fig.105

from 3 ports to 3 ports connections and segregated traffic for Tagged and Untagged Traffic, see

Fig.115.

Settings here below are intended to be done both into local and remote radio equipment. The software to

be used to configure the equipment is WEB LCT. In the following chapters all configuration steps are shown

using WEB LCT.

20.2 LOCAL LAN-1 PORT TO REMOTE LAN-1 PORT TRANSPARENTCONNECTION LAN PER PORT

Settings for Untagged and Tagged Traffic

Fig.97 - Local Lan-1 port to remote Lan-1 port connection

The first example is local Lan1 port to remote Lan1 port transparent connection for tagged and untagged

traffic please refer to Fig.97.

Fig.98 - Modulation and capacity

Select 1+0 or 1+1 configuration according system requirements.

Please refer to Fig.98. First selection is channel bandwidth and modulation, in this example we selected

28MHz and 16QAM.

ACM Engine, Upper Modulation, Lower Modulation, Permanent Traffic and extra TDM Capacity at any mod-

ulation must be the same local and remote.

The troughput at any modulation with 28 MHz bandwidth is shown in Fig.99 with View Current Config but-

ton ofFig.98.

Fig.99 - View Current Configuration

So with 4QAMstrong modulation the Ethernet capacity is 20 Mbit/s and with 256QAM modulation the Eth-

ernet capacity is 140 Mbit/s.

Fig.100 - Switch general settings

See Fig.100 for general settings of the switch. All the used ports must be Enabled, so enable Lan-1 and

Internal Port A, see Fig.101.

Please notice the MAC Address Aging Time reduced, only for this test at 15 sec.

The other ports should be disabled. The correct cable crossover arrangement must be selected too (see

Fig.101). Enable LLF, if needed, only at the end of link line up.

Select Master or Slave Role for 1000BaseT interface.

Switch connections are done with Lan per port selections. Referring to Fig.102, incoming traffic at Lan-1

exits at internal Port A and as in Fig.103 and in Fig.104 incoming traffic at internal Port A exits at Lan-1

port. This connection are done for all Untagged packets and all Tagged packets with Vlan Id not described

into Vlan Configuration Table.

If Vlan Configuration Table is blank all Tagged traffic follows the rules of Lan per port.

Possible selections of Ingress Filtering Check:

"Disable 802.1q": no check of Virtual Lan tag is done and all packets follow Lan per port settings

"Fallback": if Tagged packets have their Vlan Id into Vlan Configuration Table they follow the con-

nection described into the table, otherwise they follow the Lan per port settings as Untagged pack-

ets

"Secure": no Untagged packet transits; only Tagged packets with Vlan Id listed into the table can

transit.

For all previous configuration "Disable 802.1" should be selected. With Egress Mode as Unmodified the out-

going packets at Lan-1 port exit Untagged or Tagged exactly as they were Untagged or Tagged at the in-

coming port.

20.3 FROM 3 PORT TO 3 PORT CONNECTIONS

Settings for Untagged traffic.

Fig.105 - 3 ports to 3 ports connections with segregated traffic

In this example 3 local port must communicate with corresponding 3 remote ports. All the ports share the

same radio channel but traffic originated and directed to Lan1 should be kept separated from traffic from

Lan2 and Lan3 and viceversa.

Lan-1 to Lan-1, connection must transfer untagged packets.

Lan-2 and Lan-3 have the same requirements. Please refer to Fig.105.

Select 1+0 or 1+1 configuration according system requirements.

See Fig.108 for Switch general settings of the switch. All the used ports must be Enabled, so enable Lan-

1, Lan-2, Lan-3 and Internal Port, see Fig.109.

Please notice the MAC Address Aging Time reduced, only for this test, at 15 sec. The correct cable crossover

arrangement must be selected too (see Fig.109). Enable LLF if needed only at the end of link line up.

Select Master or Slave Role for 1000BaseT interface.

For Untagged traffic, connections are done with Lan per port selections. Referring to Fig.110 incoming traf-

fic at Lan-1 exits at internal Port A and into Fig.113 incoming traffic at internal Port A exits at Lan-1 port.

This connection are done for all Untagged traffic and all Tagged packets with Vlan Id not described into

Vlan Configuration Table.

If Vlan Configuration Table is blank all Tagged traffic follows the rules of Lan per port.

Possible selections of Ingress Filtering Check:

"Disable 802.1q": no check of Virtual Lan tag is made and all packets follow Lan per port settings

"Fallback": if Tagged packets have their Vlan Id into Vlan Configuration Table they follow the con-nection described into the table, otherwise they follow the Lan per port settings as Untagged pack-

ets

"Secure": no Untagged packet transits; only Tagged packets with Vlan Id listed into the table can

transit.

Fig.109 - Lan-1 interface settings

All the used ports must be Enabled.

The correct Cable Crossover arrangement must be selected too.

Untagged traffic transits only if the selection for Ingress Filtering Check is disabled at each input port and

a separated Vlan for Untagged traffic is set up for each port.

Each port of the switch must be associated with a different Default VLAN ID, Lan-1 with Default VID 4001,

Lan-2 with Default VID 4002, Lan-3 with Default VID 4003, for Lan-1 see Fig.109 and Fig.110.

Untagged packets coming at physical ports are tagged on common radio channel but tagged with different

Vlans. At receiving end packets are distributed at their ports and untagged.

Vlan Configuration Table will be defined in order to group traffic from Lan-1, Lan-2, Lan-3 to Port A.

The Vlan Configuration Table must be programmed as in Fig.114.

See Fig.118 for Switch general settings of the switch. All the used ports must be Enabled, so enable Lan-

1, Lan-2, Lan-3 and internal Port A, see Fig.101.

For already Tagged traffic we need to add a second Vlan Tag to the packets creating the Vlan of Vlan into

radio channel, so we need a Max packet size of 2048.

Settings are as reported in Fig.119, Fig.120, Fig.121, Fig.122, Fig.123.
