4000 Router Series ACL and QoS Command Reference

acl [ ipv6 ] acl-number: Performs GTS for packets matching an ACL specified by its number. The value

range for the acl-number argument depends on the device model. If ipv6 is not specified, this option

specifies an IPv4 ACL. If ipv6 is specified, this option specifies an IPv6 ACL.

cir committed-information-rate: Specifies the CIR in kbps. The value range for this argument depends on

the device model.

cbs committed-burst-size: Specifies the CBS in bytes. The default CBS is the amount of traffic transmitted

at the rate of CIR in 500 milliseconds. If the calculated default CBS is smaller than 1000, the value 1000

applies.

ebs excess-burst-size: Specifies the EBS in bytes, which specifies the traffic exceeding CBS when two

token buckets are used. The default EBS is 0 (one token bucket is used).

queue-length queue-length: Specifies the maximum queue length in the buffer, in the range of 1 to 1024

and defaulting to 50.

Examples

# Shape the packets matching ACL 2001 on Ethernet 1/1. The GTS parameters are as follows: CIR is

200 kbps, CBS is 50000 bytes, EBS is 0, and the maximum buffer queue length is 100.

Parameters

interface-type interface-number: Specifies an interface by its type and number. If no interface is specified,

this command displays the rate limit configuration and statistics on all the interfaces.
