Hi Hoan,
If you want to remove a single statement, you can do it like this:
ASA1# show run access-list
access-list MY_ACL extended permit ip any host 192.168.1.1
access-list MY_ACL extended permit ip any host 192.168.1.2
access-list MY_ACL extended permit ip any host 192.168.1.3
Let’s remove the middle statement:
ASA1(config)# no access-list MY_ACL extended permit ip any host 192.168.1.2
And verify our work:
ASA1# show run access-list
access-list MY_ACL extended permit ip any host 192.168.1.1
access-list MY_ACL extended permit ip any host 192.168.1.3
That’s it.
Rene
