Configure filters without sequence number If you are creating an extended ACL with only one or two filters, you can let FTOS assign a sequence number based on the order in which the filters are configured. FTOS assigns filters in multiples of 5. To configure a filter for an extended IP ACL without a specified sequence number, use any or all of the following commands in the IP ACCESS LIST mode: Command Syntax {deny | permit} {source mask | any | host ip-address} [count [byte] | log ] [order] [monitor] [fragments] {deny | permit} tcp {source mask] | any | host ip-address}} [count [byte] | log ] [order] [monitor] [fragments] {deny | permit} udp {source mask | any | host ip-address}} [count [byte] | log ] [order] [monitor] [fragments] Command Mode CONFIG-EXT-NACL CONFIG-EXT-NACL CONFIG-EXT-NACL Purpose Configure a deny or permit filter to examine IP packets. • log and monitor options are supported on E-Series only. Configure a deny or permit filter to examine TCP packets. • log and monitor options are supported on E-Series only. Configure a deny or permit filter to examine UDP packets. • log and monitor options are supported on E-Series only. When you use the log keyword, CP processor logs details about the packets that match. Depending on how many packets match the log entry and at what rate, the CP may become busy as it has to log these packets' details. The following example illustrates an extended IP ACL in which the sequence numbers were assigned by the software. The filters were assigned sequence numbers based on the order in which they were configured (for example, the first filter was given the lowest sequence number). The show config command in the IP ACCESS LIST mode displays the two filters with the sequence numbers 5 and 10. FTOS(config-ext-nacl)#deny tcp host 123.55.34.0 any FTOS(config-ext-nacl)#permit udp 154.44.123.34 0.0.255.255 host 34.6.0.0 FTOS(config-ext-nacl)#show config ! ip access-list extended nimule seq 5 deny tcp host 123.55.34.0 any seq 10 permit udp 154.44.0.0 0.0.255.255 host 34.6.0.0 FTOS(config-ext-nacl)# To view all configured IP ACLs and the number of packets processed through the ACL, use the show ip accounting access-list command in the EXEC Privilege mode.
