Assigning an Access List to a Port
To validate a frame that is attempting to exit through an NML port, the port
consults an access list. If the CUGID on the frame matches a CUGID on the list,
the port takes the action you have specified: forwarding the frame and discarding
the CUGID, forwarding the frame and retaining the CUGID, or dropping the
frame.
You create an inclusive list or an exclusive list for each NML port that supports
the closed user group. When the port finds a match on an inclusive list, it forwards
the frame. When the NML port finds a match on an exclusive list, it drops the
frame.
To assign an access list to a port so that you can specify a start and end range of
CUGIDs for the circuit on which the port is located:
1. Select Protocols > NML > Interfaces from the Configuration Manager
window (r
efer to Figure 5-3).
The NML Interfaces window appears (refer to Figure
5-4).
2. Click on Security List.
The NML Filters window appears (Figure
5-5).
