Traffic Classes
When entering a match/ignore command in an IPv4
or IPv6 class, type ? to display a list of valid ip-
protocol entries.
• In an IPv4 class, you can enter any of the
following IPv4 protocol match criteria:
ahesp gre icmp* igmp*
ipip-in-ip ipv6-in-ip ospf pim
sctptcp* udp* vrrp
* For IPv4 ICMP, IGMP, TCP, and UDP packets, you
can enter additional match criteria; see:
“Optional ICMP Match Criteria” on page 8-14
“Optional IGMP Match Criteria” on page 8-17
“Optional TCP and UDP Match Criteria” on page
8-18
To specify an IPv4 protocol as match criteria, you
can also enter its protocol number. Valid values are
from 0 to 255.
For example, 8 means Exterior Gateway Protocol;
121 means Simple Message Protocol. For a list of IPv4
protocol numbers and corresponding protocol
names, refer to the IANA “Protocol Number Assign-
ment Services” at www.iana.com.
• In an IPv6 class, you can enter any of the
following IPv6 protocol match criteria:
ahesp icmp* ipv6
sctptcp* udp*
* For IPv6 ICMP, TCP, and UDP packets, you can
enter additional match criteria; see:
“Optional ICMP Match Criteria” on page 8-14
“Optional TCP and UDP Match Criteria” on page
8-18
