numbered ACL's

Unanswered Question
Sep 5th, 2007

I have been working with named (I believe they are called "extended acls"??) for the past few years - I just began working on a router that is using numbered acls - I thought numbered acls did not offer the flexibility to edit them line by liine, I seem to remember having to remove the acl and reapply it? Is this true or is my memory faulty?

2801 router / IOS 12.4

I have this problem too.

Dan :

Numbered ACLs can be edited just like named ACLs .

here is an example from a 2801 router.

D-R2801-13A(config)#ip access-list extended 100


Ext Access List configuration commands:

<1-2147483647> Sequence Number

default Set a command to its defaults

deny Specify packets to reject

dynamic Specify a DYNAMIC list of PERMITs or DENYs

evaluate Evaluate an access list

exit Exit from access-list configuration mode

no Negate a command or set its defaults

permit Specify packets to forward

remark Access list entry comment

Thanks, in the past were there limitations with numbered acls? why would someone use one or the other or simply preference?

Hi Dan,

Yes formerly numbered ACL couldn't be edited, but in the recent codes, you can edit a numbered ACL the same as named ACL, using this or that is simply preference like you've said.
