match fr-de
You must use the ip keyword to match DSCP values for IPv4 packets. The router supports only
DSCP matching of IPv4 packets.
You must use the ip keyword to match precedence values for IPv4 packets. The router supports only
precedence matching of IPv4 packets.
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.
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.
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.
