I am planning to deploy an access-list 3 permit statement to all the network devices I have in CiscoWorks which includes a large number of switches and routers. Would it be easier to deploy to all devices at one time or break it down to go to device groups instead? This is my first time using this feature so any suggestions would be very helpful.
If it's the first time you've used Netconfig, I recommend a small test set first to make sure it works as you expect. After that, you can deploy to the rest of your devices. As with any ACL manipulation, be very careful you don't lock yourself out of the current device, or on subsequent devices in your job. This means be absolutely sure what protocols will be used to deploy the changes (e.g. TFTP, telnet, SSH ,etc.) as well as which protocols will be used to re-fetch the changed config.
