Remove ACL

[giacomo12]

Hi,

I'm involved in a Packet Tracer exercise.

I have to remove an extended ACL 110 from a router (R1):

I type: R1#(config) no access-list 110

Now the network devices warks as I want, but the output of "R1#show running-config" still show me  the extended ACL 110. Why?

Thanks

since it is an extended acl the commando should be "no ip access-list extended 110"

[giacomo12]

Thanks, but I'm having the same result. In the running configuration the extended ACL is still there

[marc.groenen]

Can you post the output of the show running command for that ACL ?

[giacomo12]

The ACL 101 has been configured on interface S0/0/0:

R1#show running-config

I dont see the ACL in the configuration.

Only under int S0/0/0 you are using access-list 101 do you want to remove this ?

Then you can type 

conf t

int s0/0/0

no ip access-group 101 out

end

So in fact the ACL is gone ( or removed from the configuration) but the commands referring to the ACL (ie. ip access-group under interface or ACL under SNMP community or ACL under VTY) will still be intact. You have to remove these manually.
