Usage Guidelines for match Commands
match ip dscp
• You must use the ip keyword to match DSCP values for IPv4 packets. The router supports only
DSCP matching of IPv4 packets.
match ip precedence
• You must use the ip keyword to match precedence values for IPv4 packets. The router supports only
precedence matching of IPv4 packets.
match ip rtp
• Use this command to match IP RTP packets destined to all even-numbered user datagram port (UDP)
port numbers in the range you specify.
• Matching on the RTP port range is particularly effective for applications that use RTP, such as voice
or video.
match mpls-experimental-topmost
• Use this command to include matching on the EXP bit value on the topmost label entry of the packet.
• You can enter this command on input and output interfaces.
• This command matches only on MPLS packets.
match not
• Use this command to specify a QoS policy value that is not used as a match criterion. When you use
the match not command, all other values of that QoS policy become successful match criteria.
For example, if you enter the match not qos-group 4 command in class-map configuration mode,
the specified class accepts all QoS group values except 4 as successful match criteria.
