Command History
Usage Guidelines The match command is used to specify which fields in the incoming packets are examined to classify
the packets. Only the IP access group or the MAC access group matching to the Ether Type/Len are
supported.
To define packet classification on a physical-port basis, only one match command per class map is
supported. In this situation, the match-all and match-any keywords are equivalent.
access-group
acl-index-or-name
Number or name of an IP standard or extended access control list (ACL) or
MAC ACL. For an IP standard ACL, the ACL index range is 1 to 99 and 1300
to 1999. For an IP extended ACL, the ACL index range is 100 to 199 and
2000 to 2699.
class-map
class-map-name
Name of predefined class map for classification that is performed on a
per-port per-VLAN basis.
ip dscp dscp-list List of up to eight IP Differentiated Services Code Point (DSCP) values to
match against incoming packets. Separate each value with a space. The range
is 0 to 63. You also can enter a mnemonic name for a commonly used value.
ip precedence
ip-precedence-list
List of up to eight IP-precedence values to match against incoming packets.
Separate each value with a space. The range is 0 to 7. You also can enter a
mnemonic name for a commonly used value
vlan vlan-list List of VLANs to match against incoming packets. You can enter up to 30
VLAN IDs. Use a hyphen for a range of VLANs. A VLAN range is counted
as two VLAN IDs. Use a space to separate individual VLANs. The range is
1 to 4094.
