The filter is a default filter for running NSNA (Nortel Secure Network Access). This allows our SNAS (Secure Network Access Switch) to be able to control the ports on the switch. We do this for visualization of switches in a large deployment. The ACT is an Access Control Template, that defines within the frame what information that I will gather to use with ACL/ACE's (Access Control Lists/Access Control Entry's). Instead of grabbing all of the information in a frame, it is more efficient to just grab the stuff that the ACE's will be using. Line #2 is for IP (0800) traffic, and line #3 is for non-IP traffic.
Since these are not configured you are not implementing NSNA. You don't need to delete these as there is no ACL/ACE using them, thus it is not active.
