Procedure
Use the dscp command, followed by a DSCP value (from 0 to 63) to apply the rule to
all packets with the specified DSCP value.
For example, the following rule is defined to capture all VoIP Bearer packets (DSCP =
46):
Gxxx-001(super)# ip capture-list 520
Gxxx-001(super-Capture 520)# ip-rule 20
Gxxx-001(super-Capture 520/ip rule 20)# composite-operation capture
Done!
Gxxx-001(super-Capture 520/ip rule 20)# dscp 46
Done!
Gxxx-001(super-Capture 520/ip rule 20)#
