Configuring IPX QoS Policies | Cabletron Systems SmartSwitch

Chapter 19: QoS Configuration Guide

Setting an IP QoS Policy

To set a QoS policy on an IP traffic flow, enter the following command in Configure mode:

Set an IP QoS policy.

qos set ip <name> <priority> <srcaddr/mask>any <dstaddr/mask>any <srcport>any <dstport>any <tos>any <port list><interface-list>any<protocol>any <tos-mask>any<tos-precedence- rewrite>any <tos-rewrite>any

For example, the following command assigns control priority to any traffic coming from the 10.10.11.0 network:

ssr(config)# qos set ip xyz control 10.10.11.0/24

Specifying Precedence for an IP QoS Policy

To specify the precedence for an IP QoS policy, enter the following command in Configure mode:

Specify precedence for an IP QoS policy.

qos precedence ip [sip <num>] [dip <num>] [srcport <num>] [destport <num>] [tos <num>] [protocol <num>] [intf <num>]

Configuring IPX QoS Policies

To configure an IPX QoS policy, perform the following tasks:

1.Identify the Layer-3 or 4 flow, and set the IPX QoS policy.

2.Specify the precedence for the fields within an IPX flow.

Setting an IPX QoS Policy

To set a QoS policy on an IPX traffic flow, enter the following command in Configure mode:

Set an IPX QoS policy.

qos set ipx <name> <priority> <srcnet>any <srcmask>any <srcport>any <dstnet>any <dstmask>any <dstport>any <port list><interface- list>any
