IPv6 ACL-based rate limiting
2
Syntax: show policy-map [map-name]
The map-name variable limits the display of policy map configuration information to the map
specified. If this variable is not used, configuration information will be displayed for all policy maps
configured on the device.
Output such as the following will display.
This display shows the following information.
IPv6 ACL-based rate limiting
Rate-limiting is supported for both inbound and outbound traffic on an interface. Rate-limiting IPv6
traffic on an interface is performed by classifying traffic using an IPv6 access-list.
IPv6 ACL based rate-limiting configuration considerations
• IPv6 ACL based rate-limiting can be configured only on a physical interface.
• IPv6 ACL based rate-limiting can be configured separately for inbound and outbound traffic on
an interface.
TABLE 11 Rate limit policy map parameters
This field... Displays...
policy-map The name of the policy map whose configuration is being displayed
cir The value of the Committed Information Rate (CIR) configured for this policy map.
Possible values are: 1 - 10000000000 bps.
cbs The value of the Committed Burst Size (CBS) configured for this policy map.
Possible values are: 1250 - 1250000000 bytes.
eir The value of the Excess Information Rate (EIR) configured for this policy map.
Possible values are: 1 - 10000000000 bps.
ebs The value of the Excess Burst Size (EBS) configured for this policy map. Possible
values are: 1250 - 1250000000 bytes.
excess-priority The priority queue that traffic whose bandwidth requirements exceeds what is
available in the CIR bucket and is sent to the EIR bucket is set to. Possible values
are 0-3.
excess-dscp The priority queue that traffic whose bandwidth requirements exceeds what is
available in the CIR bucket and is sent to the EIR bucket is set to. Possible values
are 0-63.
