Chapter 42 Configuring PFC QoS

Configuring PFC QoS

To disable VLAN-based QoS filtering in MAC ACLs, perform this task:

Command

Purpose

 

 

Router(config)# no mac packet-classify use vlan

Disables VLAN-based QoS filtering in MAC ACLs.

 

 

Configuring MAC ACLs

You can configure named ACLs that filter IPX, DECnet, AppleTalk, VINES, or XNS traffic based on MAC addresses (IPX filtering with a MAC ACL is supported only with a PFC3).

In Release 12.2(17b)SXA and later releases in PFC3BXL or PFC3B mode, you can configure MAC ACLs that do VLAN-based filtering or CoS-based filtering or both.

In Release 12.2(18)SXD and later releases, you can globally enable or disable VLAN-based QoS filtering in MAC ACLs (disabled by default).

To configure a MAC ACL, perform this task:

 

Command

Purpose

Step 1

 

 

Router(config)# mac access-list extended

Configures a MAC ACL.

 

list_name

 

 

Router(config)# no mac access-list extended

Deletes a MAC ACL.

 

list_name

 

Step 2

 

 

Router(config-ext-macl)# {permit deny}

Configures an access control entry (ACE) in a MAC ACL.

 

{src_mac_mask any} {dest_mac_mask any}

 

 

[{protocol_keyword {ethertype_number

 

 

ethertype_mask}} [vlan vlan_ID] [cos cos_value]]

 

 

Router(config-ext-macl)# no {permit deny}

Deletes an ACE from a MAC ACL.

 

{src_mac_mask any} {dest_mac_mask any}

 

 

[{protocol_keyword {ethertype_number

 

 

ethertype_mask}} [vlan vlan_ID] [cos cos_value]]

 

 

 

 

When configuring an entry in a MAC-Layer ACL, note the following information:

•The PFC3 supports the ipx-arpaand ipx-non-arpakeywords.

•The PFC2 does not support the ipx-arpaand ipx-non-arpakeywords.

•The vlan and cos keywords are supported in PFC3BXL or PFC3B mode with Release 12.2(17b)SXA and later releases.

•The vlan and cos keywords are not supported in MAC ACLs used for VACL filtering.

•With Release 12.2(18)SXD and later releases, the vlan keyword for VLAN-based QoS filtering in MAC ACLs can be globally enabled or disabled and is disabled by default.

•You can enter MAC addresses as three 4-byte values in dotted hexadecimal format. For example, 0030.9629.9f84.

•You can enter MAC address masks as three 4-byte values in dotted hexadecimal format. Use 1 bits as wildcards. For example, to match an address exactly, use 0000.0000.0000 (can be entered as 0.0.0).

•You can enter an EtherType and an EtherType mask as hexadecimal values.

•Entries without a protocol parameter match any protocol.
