Introduction (2)

In this presentation we shall focus on the L2 ETH switch:

• Four priority (CoS) queues

• Advanced CoS classifier:

VLAN Pbits / VLAN ID (RFC 802.1p,q)

IPv4 (RFC 791) / IPv6 (RFC 2460, RFC 2474)

MAC DA

• Advanced ingress traffic policing /

rate-limiting per port/CoS

• Flexible scheduling:

Strict Priority, WRR or HRR

L2 ETH

SWADM


• Traffic shaping

• 802.3x flow control (for loss-less) operation

IP-10G L2 ETH Switch Ports

The IP-10G’s L2 Switch has 8 ports:

• Port #1 GbE (Opt. / Elec.)

• Port #2 GbE (Opt. / Elec.)


• Port #3 to port #7 FE

• Port #8 (Radio port)

5

Step #1: Set your Switch

• Configure the switch mode: Pipe / Managed / Metro

• Configure VLAN IDs

Basic Configurations

1. Ingress Rate Limiting

Let’s say we want to limit Video streams

from customer interface towards the

network


UDP protocol & multicast address

Therefore we shall define a Policer to

limit these parameters

1. Ingress Rate Limiting – Setting a Policer

There are 15 differenttraffic types that we

can use

Each Policer can have

up to 5 conditions


1. Attaching a Policer to a port

To attach a Policer to a port simply type the Policer name

2. Queuing according to Ingress P-Bits

Click on the VLAN Pbits to Queue link to open the configuration table

Using this table we can map 8 priority levels to 4

queues or lower number of classes

This table is global and can be used for other tasks

as well


2. Queuing according to Ingress P-Bits

Select “VLAN Pbits” as the 3rd classifier as shown below:

Set the Egress Scheduler as required -

3. Queuing Ingress Frames according to MAC

Click on the Static MAC link to open the configuration table


In this example, we prioritize 3 frames according to their MAC DA.

The ingress frames are put in a queue according to the Priority settings andVLAN P-Bits to Queue

table. Ingress frames with MAC DA that are not listed in this table will be handled by the next

classifiers .

3. Queuing Ingress Frames according to MAC

Next, select “Queue Decision” as the 1st criteria



Frames with MAC that do not compl y to the table will be classified by the 2nd &

3rd classifiers

4. Queuing Ingress Packets according ToS / DSCP

Click on the “IP Pbits to Queue”

Link to configure ToS /DSCP for IPv4

or IPv6


4. Queuing Ingress Packets according ToS / DSCP

Next, select “IP-TOS ” as the 3rd criteria

5. Assigning Port traffic to a specific Queue

Select “Port ” as the 3rd criteria

Select to which queue the port should assign the ingress frames



6. Queuing Ingress frames according to VLAN ID

Click on the “VLAN ID to Queue” Link to configure the table

6. Queuing Ingress frames according to VLAN ID

Select “Queue Decision” as the 2nd criteria



Frames with VID that do not comply to the table will be classified by the 3rd

classifier

7. Egress Shaper

• Reducing the egress rate to a value between 64kbps and 1Mbps requiressetting it in steps of 64kbps


• Reducing the egress rate to a value between 1Mbps and 100Mbps requiressetting it in steps of 1Mbps

• Reducing the egress rate to a value between 100Mbps and 1Gbps requiressetting it in steps of 10Mbps
