queues. Use the mls qos srr-queue output queues 8 global configuration command to enable all 8 egress
queues. Once 8 egress queues are enabled, you are able to configure thresholds, buffers, bandwidth share
weights, and bandwidth shape weights for all 8 queues. The 8 egress queue configuration is only supported
on a standalone switch.
The egress queue default settings are suitable for most situations. You should change them only when you
Note
have a thorough understanding of the egress queues and if these settings do not meet your QoS solution.
Beginning in privileged EXEC mode, follow these steps to configure the memory allocation and to drop
thresholds for a queue-set. This procedure is optional.

DETAILED STEPS
Command or Action
Step 1
configure terminal
Example:
Switch# configure terminal
Step 2
mls qos srr-queue output queues 8
Example:
Switch(config)# mls qos
srr-queue output queues 8
Purpose
Enters the global configuration mode.
(Optional) The switch supports 4 egress queues by default, although you can enable
a total of 8 egress queues. Use the optional mls qos srr-queue output queues 8
command to enable the additional 4 egress queues.
Once 8 queue support is enabled, you can then proceed to configure the additional
4 queues. Any existing egress queue configuration commands are then modified
to support the additional queue parameters.
The option to enable 8 queues is only available on a standalone switch.
