Overview
Overview
Network queue policies define the ingress network queuing at the MDA network node level.
Network queue policies are also used at the Ethernet port and SONET/SDH path level to define
network egress queuing.
There is one default network queue policy. Each policy can have up to 16 queues (unicast and
multicast)
policy is identified as network-queue default. Default network queue policies are applied to
MDA network ingress ports. You must explicitly create and then associate other network queue
QoS policies.
For information about the tasks and commands necessary to access the command line interface
and to configure and maintain your devices, refer to CLI Usage chapter in the 7450 ESS OS Basic
System Configuration Guide.
Network Queue Parent Scheduler
Network queues support port scheduler parent priority-level associations. Using a port scheduler
policy definition and mapping network queues to a port parent priority level, HQoS functionality
is supported providing eight levels of strict priority and weights within the same priority. A
network queue's bandwidth is allocated using the "within-cir" and "above-cir" scheme normal for
port schedulers.
Queue CIR and PIR percentages when port-based schedulers are in effect will be based on frame-
offered-load calculations.
A network queue with a port parent association exists on a port without a scheduler policy defined
will be considered to be orphaned.
