The filter match list ip-prefix-list, ipv6-prefix-list, protocol-list, and port-list define a list of IP prefixes, IP protocols, and TCP-UDP ports that can be used as match criteria for line card IP and IPv6 filters. Additionally, ip-prefix-list, ipv6-prefix-list, and port-list can also be used in CPM filters.
A match list simplifies the filter policy configuration with multiple prefixes, protocols, or ports that can be matched in a single filter entry instead of creating an entry for each.
The same match list can be used in one or many filter policies. A change in match list content is automatically propagated across all policies that use that list.
