Enterasys SecureStack C2 - Configuring Policy Class of Service (CoS)

Configuring Policy Class of Service (CoS)
9-16 Policy Classification Configuration
EnterasysNetworks’enhancedCoSimplementationallowsyoutousethefollowingmethodsto
configureClassofServiceontheSecureStackC2:
• Allowingtheswitchtoautomaticallyassignpolicy‐basedinboundratelimit ersasdescribed
inthissection.
• Configuringtransmitqueueingandratelimitingonaper‐portbasisasdescribedin
Chapter 10
.
Bydefault,policy‐basedCoSisdisabledonthedevice,anddefaultoruser‐assignedport‐based
802.1D(802.1p)settingsareusedtodeterminetrafficratelimiting.Whenpolicy‐basedCoSis
enabled,thedefaultanduser‐assignedpolicy‐basedsettingswilloverrideport‐basedsettings
describedinChapter 10.
About Policy-Based CoS Configurations

canaddtothepolicy‐basedCoSfunctionbydefiningnewportgroupings,andassigninginbound
ratelimiters.Theprocessforuser‐definedCoSconfigurationinvolvesthefollowingstepsand
associatedcommands

Example
Thisexamplecreatesdifferentinboundratelimitersfortwoportgroupsandthenassignsthemto

1. Configuretwoportgroups,oneforuserportsandoneforuplinkportsandassignportstothe

Procedure 9-1 User-Defined CoS Configuration
Step Task Command(s)
1. Enable CoS set cos state
2. Create CoS port groups set cos port-config
3. Define physical rate limiters for groups set cos port-resource
4. Create virtual reference for the IRL resource
(physical reference) for each port group
set cos reference
5. Add IRL reference to CoS settings table set cos settings
