hw-module system max-queue-limit
hw-module system max-queue-limit
To enable a user to change the queue limit for all interfaces globally use the hw-module system
max-queue-limit command. To cancel the global setting, use the no form of the command.
hw-module system max-queue-limit max-queue-limit
no hw-module system max-queue-limit max-queue-limit
Syntax Description
Defaults Not enabled by default
Command Modes Global configuration mode
Command History
Usage Guidelines This command allows you to change the queue limit for all interfaces globally rather than apply a policy
with a queue limit to all the interfcaes.
This is a global configuration command. It can be overriden by the per port, per class, queue-limit
command.
For a standalone supervisor engine, you must reboot the engine after applying this command. For a
redundant supervisor engine, you must enter the redundancy reload shelf command to enforce a reboot
on both the supervisor engines.
Examples This example shows how to set the queue limit globally to 1024:
Switch> enable
Switch# configure terminal
Switch(config)# hw-module system max-queue-limit 1024
Need to reboot to take effect max queue limit
Switch(config)# exit
Switch# reload (for standalone supervisors)
Switch# redundancy reload shelf (for reduandancy supervisors in SSO mode)
or
Switch# redundancy force-switchover (followed by another redundancy force-switchover, for
reduandancy supervisors in RPR mode
max-queue-limit Specifies the queue limit for all interfaces. Valid values are from
1024 to 8184. This parameter must be a multiple of 8.
Release Modification
15.0(2)SG1, and
3.2.1SG
Support for this command was introduced on the Catalyst 4500 series switch.
