Chapter 42 Configuring PFC QoS

Configuring PFC QoS

PFC QoS Policy Configuration Overview

Note To mark traffic without limiting bandwidth utilization, create a policer that uses the transmit keywords for both conforming and nonconforming traffic.

These commands configure traffic classes and the policies to be applied to those traffic classes and attach the policies to ports:

access-list(Optional for IP traffic. You can filter IP traffic with class-mapcommands.):

PFC QoS supports these ACL types:

Protocol

Numbered ACLs

Extended ACLs

Named ACLs

 

 

 

 

IPv4

Yes:

Yes:

1 to 99

100 to 199

 

 

1300 to 1999

2000 to 2699

 

 

 

 

 

IPv6

Yes (named)

Yes

 

 

 

 

IPX

Yes: 800 to 899

Yes: 900 to 999

Yes

(Supported only with PFC2)

 

 

 

 

 

 

 

MAC Layer

No

ARP

No

Yes

 

 

 

 

The PFC3 supports IPv6 named extended ACLs and named standard ACLs in Release 12.2(18)SXE and later releases.

The PFC3 supports ARP ACLs in Release 12.2(18)SXD and later releases.

Note —The PFC2 applies IP ACLs to ARP traffic.

—The PFC3 does not apply IP ACLs to ARP traffic.

—With a PFC3, you cannot apply microflow policing to ARP traffic.

The PFC3 does not support IPX ACLs. With the PFC3, you can configure MAC ACLs to filter IPX traffic.

With a PFC2, PFC QoS supports IPX ACLs that contain a source-networkparameter and the optional destination-networkand destination-nodeparameters. PFC QoS does not support IPX ACLs that contain other parameters (for example, source-node, protocol, source-socket, destination-socket, or service-type).

With a PFC2 or PFC3, PFC QoS supports time-based Cisco IOS ACLs.

Except for MAC ACLs and ARP ACLs, refer to the Cisco IOS Security Configuration Guide, Release 12.2, “Traffic Filtering and Firewalls,” at this URL:
