Configuring Your Device

Setting	Description

Segment	For switching hubs, the segment that the port is on.

Last Source Address	The address of the last device that sent packets through this
	port.
Security Violation	States whether there is a security violation or no violation.

	Bridge Enable/Disable
	Select the Bridge Enable/Disable button to enable or disable the internal bridge
	between the 10 Mbps and 100 Mbps segments in the hub.

N o t e	It is recommended that this setting remain enabled for optimum connectivity.
	You may want to disable the bridge:
	■ To connect the segments via and external switch
	■ To simplify the network for troubleshooting.
	Backup Links
	Backup Links
	A backup link (hubs only) configures two ports on one hub to create a
	redundant connection to another device. This provides a connection with
	fault-tolerant capability for highly reliable networking. One port is designated
	the primary port; the second port is the backup port. The backup port becomes
	active only if the primary port becomes inoperative. Any of the network ports
	(twisted-pair, ThinLAN, or AUI/Xcvr) can be used as the primary port or
	backup port.

Port 2 is assigned as a backup port to Port 1, which connects to a device with MAC address 0060b0- 897b00.
