set cos port-resource flood-ctrl

Usage

CoS port resources are where actual physical rate limiters are configured. Resources map directly to the number of rate limiters supported by the port type. (Port type 0 supports 100 IRL resources.) Resources exist for each port group and are indexed as group#.port‐type.irl‐index. Port resources are not initially configured as rate limiting.

Inbound rate limiting, or rate policing, simply drops or clips traffic inbound if a configured rate is exceeded. CoS inbound rate limiting allows the user to configure rate limits based on kilobits per second.

The show cos port‐resource command displays the resources available for each port group. By default, no IRL resources are configured. The default Rate Limiting algorithm is drop and cannot be configured otherwise.

Example

This example sets the inbound rate limit resource index number 1 for port group 2.0 to 10000 Kbps or 1 MB:

C3(su)->set cos port-resource irl 2.0 1 unit kbps rate 10000 type drop

set cos port-resource flood-ctrl

Use this command to create a CoS‐based flood control port resource. This resource specifies flood control rate limiters that can be mapped to specific ports.

Syntax

set cos port-resource flood-ctrl group-type-index{unicast multicast broadcast all} rate rate

Parameters

group‐type‐index

Specifies a port group/type index. Valid entries are in the form of

 

group#.port‐type.

 

Valid values for group# can range from 0 to 7. Valid values for port‐type

 

can range from 0 to 1, although only port type 0 is currently supported.

 

For example, port group 3 would be specified as 3.0.

 

 

unicast

Specifies rate limiting will be applied to unknown unicast traffic.

 

 

multicast

Specifies rate limiting will be applied to multicast traffic.

 

 

broadcast

Specifies rate limiting will be applied to broadcast traffic.

 

 

all

Specifies rate limiting will be applied to unknown unicast, multicast,

 

and broadcast traffic.

 

 

rate rate

Specifies a rate limit in packets per second.

 

 

Defaults

None.

Mode

Switch command, read‐write.
