Native Ethernet

The Ethernet traffic is sent over a single hop or

through a network. Native Ethernet traffic is sent over a dedicated physical link instead of being transported over PDH or SDH. Native Ethernet enables more efficient use of bandwidth and maximizes Ethernet throughput since no PDH overhead is added.

Shows an overview of the Ethernet services.

Ethernet over Packet Links via a WAN with an RL-IME Group

Right click on the Modem Unit used for the Native Ethernet Confugue Configure

Radio Link

Configure the Capacity of the link ,in this example we have configured the link for 345

Mbit/s

We can also select the no of E1 for the TDM traffic which will reduce the capacity of

Ethernet Traffic

Now configure the LAN port from we are taking Ethernet Traffic

Assign a Switch Port to the LAN port ,here we have assigned Switch port 1

Now configure RL-IME link for Ethernet Traffic, here we will configure RL-IME 1/7/100

Right click oon RL-IME 1/7/100 Configure

Assign the Packet link to RL-IME group, here we have assign Modem unit no 2 (MMU2H)

Select link then press

button

Now packet link is assigned for RL-IME 1/7/100

A WAN port with name “WAN 1/7/100” will be automatically corresponding to RL-IME

1/7/100 now we have to configure this WAN port

Assign Switch port to the WAN 1/7/100,here we have given port no 2

We can see the configuration of any Switch port, we can see here that Switch port no 1 is

assigned to LAN 1/7/3,we need to take care that LAN port should be configured as UNI

Switch port 2 is assigned to WAN port & It should be configured as NNI

No we need to configure the VLAN for layer 2 switching,

We have Default VLAN with VLAN ID 1,this should be always there and all ports should

be defined in Default VLAN,

After creating VLAN we can see that the LAN port is UP & Receiving & Transmitting the

Ethernet Frames

We can also see that the Radio link is carrying Ethernet traffic now

Another Radio link we have configured with less Ethernet traffic

Check the WAN port status now

We have now observed both WAN port are UP & having traffic

Ethernet Over PDH

In EoPDH we can carry Ethernet Traffic over existing PDH link.

Above Figure shows an overview of the Ethernet services for Ethernet

over PDH.

Right Click on PDH-IME ->Configure->General

Select Connect to as “Ethernet", after that Save button will be highlighted, save the configuration by

pressing Save button

Again Click on PHD-IME ->Capacity

Configure the link capacity

One WAN port will be created corresponding to the PDH-IME.

Ethernet Over SDH

In EoSDH we can carry Ethernet Traffic over existing SDH link.

Above Figure shows an overview of the Ethernet services for Ethernet over

PDH.

Configure Structure AU-4/VC-4

Configure Structure AU4/VC-4

We have Defined Structure as AU-4

Configure link for Ethernet Traffic

Define Concatenation

Define VCG to configure Ethernet over SDH

Select required VCG & press forward button

WAN port would be automatically created corresponding to the VCG 1/8/101

Now configure Ethernet Over SDH

Configure VCG 1/8/99 with Packet link 1/4/1

Assign Switch port to the WAN 1/8/101

Assign Switch port for LAN port

Configure VLAN

Complete VLAN configuration with VLAN ID & Switch ports, after that the link will be

active for Ethernet Over SDH

Simple Bridge

Configuration

Assign the Nuber of E1s for TDM traffic & Capacity for Ethernet Traffic

Adaptive

Modulation

Hitless Adaptive Modulation is supported by MMU2 H and enables automatic

switching between different modulations, depending on radio channel

conditions. Hitless Adaptive Modulation makes it possible to increase the

available capacity over the same frequency channel during periods of normal

propagation conditions.

Configure the Minimum & Maximum Capacity of the link for the QOS

We can see that in good condition link capacity is 154 Mbps with 128 QAM

When radio conditions goes bad then link capacity reduces to 90 Mbps with 16 QAM to make sure that the

impotant date still running on the microwave link.

Frame

Addmission

Frame admittance - It is possible to block or admit the following frame types at

the network edge:

Q-Tagged (priority bits/VID set in Q-tag)

Priority tagged (only priority bits set in Q-tag)

Untagged (no Q-tag)

Other/unrecognized frame types (for example S-tags) are discarded at the

network edge.

We can defined the type of frames we want to access ,default is Admit All

We have 2 options:-

1. Admit Only VLAN-tagged Frames

2. Admit Only Untagged And Priority-tagges frames

Link Aggregation group

LAG

Link Aggregation Group (LAG),

which aggregates several external

Ethernet links into one logical link

and provides line protection.

Right Clink on Ethernet-Switch ConfigureLAG

Click Add Row button

Define Master port & Member ports for LAG

Save the configuration by clicking Save button

MAC Address

limiting per

port

MAC address limiting per port. It is possible to limit the MAC address table per port

to prevent external devices/networks to flood the customer network with MAC

addresses.

It will allow operator to set the limit of the MAC address in Network as per the

requirment.

Click on Switch port & define Maximum Learned MAC address, In out example Switch port will

listen only 20 MAC address & drop all other data.

Default value is 0 which means it will learn all MAC addresses. Maximum Value is 0 to 16383

MAC WHITE

LIST

A source MAC address based white list can provide port access control at the

network edge

Right Click on Ethernet Switch Conofigure MAC white list

Click on Add Row

Configure White list Name & click Save

Give MAC address and again click Save

Now configure the Switch port, now in example now Switch port 1 will only listen data from MAC

addess 00:00:00:00:00:01

Now Switch port is configured for MAC White list “test”

If we wish to delete MAC white list then we have to make sure it is not assiegned to any Switch port

else we will face Error messege

It gives the facility to measure the traffic on any port to be mirrored on another port for

quality measurement, Wire shark is best tool to get the output on local machine for

investigation

Port Mirroring

Right Clickn on Ethernet Switch Tools Port Mirror

Click on Add Row

Now here we have mirroed port no 2 to port no 5, Port no 5 is connecte to external machine like

laptop not using Wire shark we can monitor all data going Via port no 2

RSTP activates a redundant link in case of link failure and protects the

network from infinite loops

Rapid

Spanning Tree

protocol

Right Click on Ethernet Switch Configure Spanning Tree

Configure STP as RSTP & save the configuration.

Select all WAN ports to aviod looping,we have no need to select LAN ports

Static Unicast Filtering

Right Click on Ethernet Switch Configure Static Unicast Filtering

Select VLAN no (here we have taken VLAN-222)

Click on Add Row, Select required Switch port

Right Click on Ethernet Switch Configure Static Multicast Filtering

Configure the Static Egress ports for the Multicast & save the configuration

Layer 1 Connection

Right click on Layer 1 Connection & go to Configure

Define the WAN & LAN port you want to configure for the Layer 1 Configuraion & save it

Weighted Fair Queuing

(WFQ).

A potential problem with strict priority scheduling

is that queues with lower priorities may be

starved, that is, the frames in the queues are not

handled and eventually dropped. By using

Weighted Fair Queuing (WFQ) it is possible to

avoid starvation. When WFQ is used, queues

can be configured with a weight parameter,

which decides how large share of the available

output port bandwidth that is dedicated to the

specific queue,

• Example to understand WFQ

Right Click on Ethernet Switch Configure General

Click on “Configure QoS”

Select the Scheduling profile as per design

Click yes

Now WFQ is configured

Clink on Configure Queues

,check next slide

Queue is configured now

Click on Configure Queue Size & check

next Slide

Here we can define Queue size as per Traffic class to maintain QOS

Now check another option & see the “Configure Queue”

We can see that the Scheduling is now different as per Network priority

Now we selected another Scheduling profile

We can see that the Scheduling is now different as per Network priority

Layer 1 & layer 2 Connection

Wizard

Select Wizards Go to Layer 1 Connection Wizard

Click on Next (option will be I down right side of window)

Now layer 1 connection configuration is going on

Select required link and click on Next

Select RL-IME link and press Next

Select Packet link & press Nest

Select Link Capacity & press Next

Select LAN port & press Next

Select LAN speed is Auto (we have other option as “Full duplex” and “Half Duplex”

Select Scheduling profile for QoS

Now configure Queues and press Next

Now you will get the detail of configuration we have done so far,now click Finish to complete the

configuration
