Protocol Filters Menu
This menu is accessed from the Filters and Port Security menu.
To filter data based on protocol, you can define protocol classes and then assign
filtering attributes to these classes on a per port basis. The classes in protocol
filtering are based on destination service access point (DSAP) information. In
protocol filtering, each incoming frame is assigned to one of the protocol classes
based on the DSAP or Ethertype of the frame. If the DSAP is 0xAA (which
indicates the Subnetwork Access Protocol [SNAP]), the assignment is based on the
Ethertype of the SNAP header. The mapping from DSAP or Ethertype to protocol
class is common for all switch ports in a stack.
The Protocol Filters menu provides access to the Protocol Class Assignment
screen and the Port Filtering Attributes screen:
Protocol Class Assignment...
Selecting this item will open the Protocol Class Assignment screen.

Selecting this item will open the Port Filtering Attributes screen.
