IP Access Control Lists (ACL), Prefix Lists, and Route-maps | 143Figure 8-6. Command Example: show ip accounting access-listTo 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. Then use the no seq sequence-number command in the IP ACCESSLIST mode.Configure an extended IP ACLExtended IP ACLs filter on source and destination IP addresses, IP host addresses, TCP addresses, TCPhost addresses, UDP addresses, and UDP host addresses.Since traffic passes through the filter in the order of the filter’s sequence, you can configure the extendedIP ACL by first entering the IP ACCESS LIST mode and then assigning a sequence number to the filter.Configure filters with sequence numberTo create a filter for packets with a specified sequence number, use these commands in the followingsequence, starting in the CONFIGURATION mode:Note: On E-Series ExaScale systems, TCP ACL flags are not supported in standard or extended ACLswith IPv6 microcode. An error message is shown if IPv6 microcode is configured and an ACL is enteredwith a TCP filter included.FTOS(conf-ipv6-acl)#seq 8 permit tcp any any urgMay 5 08:32:34: %E90MJ:0 %ACL_AGENT-2-ACL_AGENT_ENTRY_ERROR: Unable to write seq 8 oflist test as individual TCP flags are not supported on linecard 0Step Command Syntax Command Mode Purpose1 ip access-list extendedaccess-list-nameCONFIGURATION Enter the IP ACCESS LIST mode by creatingan extended IP ACL.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 1813
