Configuring QoS on the Switch
Creating or Modifying the Named MAC ACLs
To create or modify a named MAC ACL, perform this task in privileged mode:
Enter the src_mac_spec and dest_mac_spec parameters as a MAC address and a mask. Each parameter
is 12 hexadecimal digits (48 bits), formatted as dash-separated pairs. Use one bits, which need not be
contiguous, where you want the wildcards. Use the any keyword for a MAC address and mask of
0-0-0-0-0-0 ff-ff-ff-ff-ff-ff. Use the host keyword with a MAC address to specify an all-zero mask
(mac_address 0-0-0-0-0-0).
Enter the ethertype parameter as 4 hexadecimal digits (16 bits) prefaced with 0x (for example, 0x0600)
or as a keyword (see the “MAC ACE Layer 2 Classification Criteria” section on page 52-21).
This example shows how to create a MAC ACE:
Console> (enable) set qos acl mac my_MACacl trust-cos aggregate my-agg any any
my_MACacl editbuffer modified. Use ‘commit’ command to apply changes.
Console> (enable)
Note The QoS MAC ACLs that do not include an EtherType parameter match the traffic with any value in the
EtherType field, which allows the MAC-level QoS to be applied to any traffic except IP and IPX.
Task Command
Step 1
Create or modify a named MAC ACL. With a PFC, PFC2, or PFC3:
set qos acl mac acl_name {dscp dscp_value | trust-cos}
[aggregate aggregate_name] src_mac_spec
dest_mac_spec [ethertype] [before editbuffer_index |
modify editbuffer_index]
Step 2
Verify the configuration. show qos acl info {acl_name | all}
editbuffer [editbuffer_index]
