Table 23-1. Parameters, Keywords, Arguments

 

 

 

 

Name

Definition

 

 

 

 

permit

Forwards the packet without changing its

 

 

priority.

 

 

 

 

use-priority

Assigns the priority that you define in the

 

 

following <priority> parameter to the packet.

 

 

 

 

<priority>

The priority that you want to assign to packets

 

 

that match this ACL. Enter a number between 0

 

 

and 7.

 

 

 

 

use-diffserv

Classifies traffic by the DSCP in the packet.

 

 

 

 

[mask]

Masks the three least significant bits of the

 

 

DSCP.

 

 

If you mask the three least significant bits of the

 

 

DSCP, the switch recognizes the remaining bits

 

 

as the precedence field of the type of service

 

 

(TOS) field and classifies the packets

 

 

accordingly.

 

 

 

 

remark-diffserv

Replaces the DSCP in the packet with the DSCP

 

 

that you enter for the following <dscp>

 

 

parameter.

 

 

The switch uses the DSCP that you enter for the

 

 

<dscp> parameter to classify the packet.

 

 

 

 

<dscp>

The DSCP that you want to replace the DSCP of

 

 

the packet.

 

 

 

 

use-l2

Classifies traffic by the layer 2 priority of the

 

 

packet. If you enter use-l2, the switch ignores

 

 

the ACL rule priority and DiffServ priority.

 

 

 

 

deny

Blocks the packet.

 

 

 

 

fwd1 fwd2 fwd3 fwd4

The priority that you want to set.

 

fwd5 fwd6 fwd7 fwd8

The number following the fwd specifies the

 

 

 

 

priority. The fwdx arguments are 1-based, while

 

 

the queue priorities are 0-based. Consequently,

 

 

the 1-based priorities are converted to 0-based

 

 

priorities by the QoS features. For example, to

 

 

specify a priority of 0, enter fwd1.

 

 

These keywords are retained from earlier

 

 

versions of software for backward compatibility.

 

 

The use-priority<priority> keyword and

 

 

argument serve the same function.
