Overview
NOTE: Access egress policies are not supported on 7210 SAS-K. Instead 7210 SAS-K support
service egress policies which allows for per SAP egress QoS differentiation using SAP based
egress queues and shapers.
An access egress policy defines the queuing for the traffic egressing on the access ports. Access-
egress queue policies are used at the Ethernet port and define the bandwidth distribution for the
various FC/queue traffic egressing on the Ethernet port.
There is one default access egress policy which is identified as policy ID 1. Each policy has 8
queues available. The Forwarding Class to queue mapping is predefined and cannot be changed.
The queue parameters like CIR, PIR, etc. can be modified. The default policy can be copied but
they cannot be deleted or modified.
Basic Configurations
A basic access egress QoS policy must conform to the following:
• Have a unique access egress QoS policy ID.
• Have a QoS policy scope of template or exclusive.
• Queue parameters can be modified, but not deleted.
