The following example shows how the seq command orders the filters according to the sequence
number assigned. In the example, filter 25 was configured before filter 15, but the show config
command displays the filters in the correct order.
Dell(conf-std-nacl)#seq 25 deny ip host 10.5.0.0 any
Dell(conf-std-nacl)#seq 15 permit tcp 10.3.0.0 /16 any
Dell(conf-std-nacl)#show config
!
ip access-list standard dilling
seq 15 permit tcp 10.3.0.0/16 any
Dell(conf-std-nacl)#
To delete a filter, use the no seq sequence-number command in IP ACCESS LIST mode.
Configuring a Standard IP ACL Filter
If you are creating a standard ACL with only one or two filters, you can let the system ssign a sequence
number based on the order in which the filters are configured. The software assigns filters in multiples of
five.
1. Configure a standard IP ACL and assign it a unique name.
CONFIGURATION mode
ip access-list standard access-list-name
2. Configure a drop or forward IP ACL filter.
CONFIG-STD-NACL mode
{deny | permit} {source [mask] | any | host ip-address} [count [byte]]
[order] [fragments]
The following example shows a standard IP ACL in which the system assigns the sequence numbers. 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.
