www.dell.com | support.dell.com To configure a filter for an extended IP ACL without a specified sequence number, use any or all of the following commands in IP ACCESS LIST mode: Command Syntax {deny | permit} {source mask | any | host ip-address} [count [byte]] [order] [fragments] {deny | permit} tcp {source mask] | any | host ip-address}} [count [byte]] [order] [fragments] {deny | permit} udp {source mask | any | host ip-address}} [count [byte]] [order] [fragments] Command Mode CONFIG-EXT-NACL CONFIG-EXT-NACL CONFIG-EXT-NACL Purpose Configure a deny or permit filter to examine IP packets. Configure a deny or permit filter to examine TCP packets. Configure a deny or permit filter to examine UDP packets. Figure 5-11 shows 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 IP ACCESS LIST mode displays the two filters with the sequence numbers 5 and 10. Figure 5-11. Extended IP ACL FTOS(conf-ext-nacl)#deny tcp host 123.55.34.0 any FTOS(conf-ext-nacl)#permit udp 154.44.123.34 0.0.255.255 host 34.6.0.0 FTOS(conf-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(conf-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 EXEC Privilege mode (Figure 5-6). Established Flag To obtain the functionality of est, use the following ACLs: • permit tcp any any rst • permit tcp any any ack 80 | Access Control Lists (ACLs)
