112 | Access Control Lists (ACLs)w w w . d e l l . c o m | s u p p o r t . d e l l . c o m To configure a filter without a specified sequence number, use these commands in the following sequence,starting in the CONFIGURATION mode:When you use the log keyword, CP processor logs details about the packets that match. Depending on howmany packets match the log entry and at what rate, the CP may become busy as it has to log these packets’details.The example below illustrates a standard IP ACL in which the sequence numbers were assigned by theFTOS. The filters were assigned sequence numbers based on the order in which they were configured (forexample, the first filter was given the lowest sequence number). The show config command in the IPACCESS LIST mode displays the two filters with the sequence numbers 5 and 10.FTOS(config-route-map)#ip access standard kigaliFTOS(config-std-nacl)#permit 10.1.0.0/16FTOS(config-std-nacl)#show config!ip access-list standard kigaliseq 5 permit 10.1.0.0/16FTOS(config-std-nacl)#To view all configured IP ACLs, use the show ip accounting access-list command in the EXEC Privilegemode as shown in the example below.FTOS#show ip accounting access example interface gig 4/12Extended IP access list exampleseq 10 deny tcp any any eq 111seq 15 deny udp any any eq 111seq 20 deny udp any any eq 2049seq 25 deny udp any any eq 31337seq 30 deny tcp any any range 12345 12346seq 35 permit udp host 10.21.126.225 10.4.5.0 /28seq 40 permit udp host 10.21.126.226 10.4.5.0 /28seq 45 permit udp 10.8.0.0 /16 10.50.188.118 /31 range 1812 1813seq 50 permit tcp 10.8.0.0 /16 10.50.188.118 /31 eq 49seq 55 permit udp 10.15.1.0 /24 10.50.188.118 /31 range 1812 1813To delete a filter, enter the show config command in the IP ACCESS LIST mode and locate the sequencenumber of the filter you want to delete.
