Configuring Queue Limits

Configuring Queue Limits
You can configure the queue limit on both ingress and egress queues. The device drops any packets that
exceed the queue limit. You use the system-defined queue classes for the type of module to which you want
to apply the policy map. See

Configuring Queuing and Scheduling on M-Series I/O Modules
Purpose
Enters global configuration mode.
Configures the policy map of type queuing, and
then enters policy-map mode for the policy-map
name that you specify. Policy-map names can
contain alphabetic, hyphen, or underscore
characters, are case sensitive, and can be up to
40 characters.
Configures the class map of type queuing, and
then enters policy-map class queuing mode.
You must select one of the system-defined
priority queues.
Assigns a queue limit based on the queue size
or percentage of the buffer memory used by the
queue. The device will drop packets that exceed
the specified threshold. You can configure the
threshold by the number of packets, number of
bytes, or the duration of time at the underlying
interface minimum guaranteed link rate. The
default threshold is in packets. The size is from
1 to 83886080. The duration is from 1 to
83886080. The percentage range is from 1 to
100.
Exits class-map queue mode and enters
policy-map queue mode.
Exits policy-map queue mode and enters global
configuration mode.
Displays information about all configured
policy maps or a selected policy map of type
queuing.
Saves the running configuration to the startup
configuration.
