description of the rule.
DSCP
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):
G350-001(super)# ip capture-list 520
G350-001(super-Capture 520)# ip-rule 20
G350-001(super-Capture 520/ip rule 20)# composite-operation capture
Done!
G350-001(super-Capture 520/ip rule 20)# dscp 46
Done!
G350-001(super-Capture 520/ip rule 20)#
IP protocol
Use the ip-protocol command, followed by the name of an IP protocol, to apply the rule to
all packets with the specified IP protocol. If you want the rule to apply to all protocols, use any
after the command (ip-protocol any).
For example, the following rule is defined to capture all TCP packets:
G350-001(super)# ip capture-list 520
G350-001(super-Capture 520)# ip-rule 20
G350-001(super-Capture 520/ip rule 20)# composite-operation capture
Done!
G350-001(super-Capture 520/ip rule 20)# ip-protocol tcp
Done!
G350-001(super-Capture 520/ip rule 20)#
To apply the rule to all protocols except the specified protocol, use the not form of this
command. For example:
G350-001(super-Capture 520/ip rule 20)# not ip-protocol tcp
Done!
G350-001(super-Capture 520/ip rule 20)#
Source or destination IP address
Use the source-ip command to apply the rule to packets from the specified IP address or
range of addresses. Use the destination-ip command to apply the rule to packets going to
the specified IP address or range of addresses.
