Configuring System Queue Limit
Note
This feature is available only from Cisco IOS Release 15.0(2)SG1 and later and Cisco IOS Release XE
3.2.1SG.
With the hw-module system max-queue-limit command, the Catalyst 4500 series switch allows you to
change the queue limit for all interfaces globally, instead of applying a policy with queue limit to all the
interfaces.
To set the queue limit globally, perform this task:
Command Purpose
Step 1
Switch# configure terminal
Enters global configuration mode.
Step 2
Switch(config)# hw-module system
max-queue-limit
max-queue-limit
Sets the queue limit for all interfaces globally.
Valid values are from 1024 to 8184. The value must be a multiple of
8.
