10.4.3.0 or later
queue-limit
Configures static or dynamic shared buffer thresholds.
Syntax
queue-limit {queue-len value | thresh-mode [dynamic threshold-alpha-value |
static threshold-value]}
Parameters
● queue-len value — Enter the guaranteed size for the queue, from 0 to 8911.
○ 45 KB (10G)/111 KB (40G) if the queue is priority flow control enabled
○ 2 KB (10G)/8 KB (40G) if the queue is lossy/link-level flow control
○ If this is a priority flow-control queue, this configuration is invalid
○ Only supported for POLICY-MAP-CLASS-MAP (pmap-c-queue) mode
● thresh-mode — (Optional) Buffer threshold mode.
● dynamic thresh-alpha-value — (Optional) Enter the value indexes to calculate the shared
threshold to the enabled dynamic shared buffer threshold, from 0 to 10. Defaults:
○ 0 = 1/128
○ 1 = 1/64
○ 2 = 1/32
○ 3 = 1/16
○ 4 = 1/8
○ 5 = 1/4
○ 6 = 1/2

Default Not configured
Command Mode POLICY-MAP-CLASS-MAP
Usage
Information
Use the queue-len value parameter to set the minimum guaranteed queue length for a queue. The
no version of this command returns the value to the default.
Example
OS10(config)# policy-map type network-qos nqGlobalpolicy1
OS10(conf-cmap-nqos)# class type network-qos nqclass1
OS10(conf-cmap-nqos-c)# pause buffer-size 45 pause-threshold 30 resume-
threshold 10
OS10(conf-cmap-nqos-c)# queue-limit 150
Example (queue)
OS10(config)# policy-map type queuing pmap1
OS10(config-pmap-queuing)# class cmap1
OS10(config-pmap-c-que)# queue-limit queue-len 100
OS10(config-pmap-c-que)# queue-limit thresh-mode static 50
