c. (Optional) Match ICMP traffic:
(global) access-list acc-list {permit | deny} icmp source-ip source-mask
destination-ip destination-mask [icmp-type [icmp-code] | icmp-message]
[precedence precedence] [dscp dscp] [tos tos]
OR

(access-list) {permit | deny} icmp source-ip source-mask destination-ip
destination-mask [icmp-type [icmp-code] | icmp-message] [precedence
precedence] [dscp dscp] [tos tos]
The access list is referenced by its name acl-name (text string) or by its number
acc-list-number (100 to 199 or 2000 to 2699).
One or more of icmp-type, icmp-type icmp-code, or icmp-message can be

message field is a text string name, chosen from the following: administratively-
prohibited, alternate-address, conversion-error, dod-host-prohibited, dod-net-
prohibited, echo, echo-reply, general-parameter-problem, host-isolated, host-
precedence-unreachable, host-redirect, host-tos-redirect, host-tos-unreachable,
host-unknown, host-unreachable, information-reply, information-request,
mask-reply, mask-request, mobile-redirect, net-redirect, net-tos-redirect, net-
tos-unreachable, net-unreachable, network-unknown, no-room-for-option,
option-missing, packet-too-big, parameter-problem, port-unreachable,
precedence-unreachable, protocol-unreachable, reassembly-timeout, redirect,
router-advertisement, router-solicitation, source-quench, source-route-failed,
time-exceeded, timestamp-reply, timestamp-request, traceroute, ttl-exceeded,
and unreachable.
d. (Optional) Match IGMP traffic:
