Filters and QOS Configuration for Ethernet Routing Switch 5500
Technical Configuration Guide
1. Overview: Ethernet Routing Switch 5500 QoS
and Filtering
The Ethernet Routing Switch 5500 supports QoS and filter configuration via WEB, CLI, and Device
Manager with no support for COPS at this time. As shown in the diagram below, the following functional
components provide QoS support on the Ethernet Routing Switch 5500:
Role Combination on the ingress port
Classify traffic at either Layer 2 or at a Layer 3/4 level
Take action by dropping, marking, redirecting, or metering (policing) traffic
Send traffic to appropriate egress queue

Role Combination
A role combination is a grouping of one or more ports, capabilities, and interface classifications against
which a policy is applied. The capabilities presently supported on the Ethernet Routing Switch 5500
include ingress IP and Layer 2 classification. The Ethernet Routing Switch 5500 supports the following
interface classes that can be applied to zero, one, or many interfaces:
Trusted Ports
o Assumes that all traffic coming into the port is originating from a trusted source. Therefore,
