Subject: Re: OT: How to make an IOS feature request
I agree, this feature is needed. Much of our Unix-based access control
is DNS based. It would be an asset to be able to configure Cisco ACLs
with permanent DNS based information.
e.g., permit ip any name *.operations.cisco.com any
I understand that name based access-control is not as secure as packet
header access-control, but the choice should be left up to the Admin.
