IPv4 Access Control Lists (ACLs)
Editing an Existing ACL
Figure 10-27. Example of Inserting an ACE into an Existing Sequence
Deleting an ACE from an Existing ACL
This action uses ACL sequence numbers to delete ACEs from an ACL.
1. To find the sequence number of the ACE you want to delete, use
show run
or
show access-list < name-str | 1 - 99 | 100-199 >
to view the ACL.
2. Use
ip access-list
to enter the “Named-ACL” (
nacl
) context of the ACE.
This applies regardless of whether the ACE was originally created as a
numbered ACL or a named ACL
.
3. In the “Named-ACL” context, type
no
and enter the sequence number of
the ACE you want to delete.
Syntax: ip access-list < standard | extended > < name-str | 1 - 99 | 100 - 199 >
no < seq-# >
The first command enters the “Named-ACL” context for the
specified ACL. The
no
command deletes the ACE corresponding
to the sequence number entered. (Range: 1 - 2147483647 )
