Configuring Filters Without a Sequence Number

If you are creating an extended ACL with only one or two filters, you can let the system assign a sequence number based on the order in which the filters are configured. The system assigns filters in multiples of five.

To configure a filter for an extended IP ACL without a specified sequence number, use any or all of the following commands:
  • Configure a deny or permit filter to examine IP packets. CONFIG-EXT-NACL mode {deny | permit} { source mask | any | host ip-address} [count [byte]] [order] [fragments]
  • Configure a deny or permit filter to examine TCP packets. CONFIG-EXT-NACL mode {deny | permit} tcp { source mask] | any | host ip-address}} [count [byte]] [order] [fragments]
  • Configure a deny or permit filter to examine UDP packets. CONFIG-EXT-NACL mode {deny | permit} udp { source mask | any | host ip-address}} [count [byte]] [order] [fragments]

The following example 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.

Example of Viewing Filter Sequence for a Specified Extended ACL 

Dell(config-ext-nacl)#deny tcp host 123.55.34.0 any
                                 Dell(config-ext-nacl)#permit udp 154.44.123.34 0.0.255.255 host 34.6.0.0
                                 Dell(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
                                 Dell(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 EXEC Privilege mode, as shown in the first example in Configuring a Standard IP ACL Filter .
