Protocol Filter Settings
Protocol Type Sets the protocol type (Ethenet, DSAP, or SNAP), and hexidecimal value associated with the specific protocol you want to filter from receiving ports.
Protocol Rate Limiting Enables or disables rate limiting for the protocol filter. If rate limiting is disabled on the switch, it is disabled for all address and protocol filters, even if rate limiting for the individual filter is enabled.  If rate limiting is enabled on the switch, it is enabled for a specific filter only if rate limiting is also enabled for the filter.
Allow the Protocol on Ports The ports on which you want frames to be received or forwarded, based on the specified protocol.  (The frames are filtered from those ports not shown.) Enter None if you want the frames filtered from all ports. Enter all if you want the frames allowed on all ports. You can list the ports individually by separating each with a comma (for example, 0,1,2,3,4,5) or you can enter a range of ports by separating the first and last port numbers in the range with a hyphen (for example, 0-5). You can also combine a list of individual entries with a range of entries (for example, 0-4,6,7). Spaces are not permitted between port numbers and the comma or hyphen.
