Bridging

Viewing Bridge	You can view bridge network status from the Monitor > Networks >

	incorporate the word “port” in the name) and shows you their states.
Viewing Bridge	The Bridge Forwarding Table is displayed in the Monitor > Routes and
Forwarding Table	Services > Bridge Forwarding screen. In addition to listing the MAC
	addresses, it provides counters for traffic passing through the bridge to
	and from the addresses.
Viewing Bridge	General bridge transmit and receive counters are located in the
Counters	Monitor > Networks > Bridge screen.

Testing Bridging	To test bridging:
	■ Attempt to communicate with the remote location using any bridged
	protocol. For example, if IP is bridged, try to PING across the WAN
	connection.
	■ If IPX is bridged, try to reach a remote server.
	■ If NetBEUI is bridged, open the Windows 95 or 98 Network
	Neighborhood to see remote Windows 95, 98, and NT machines.
