Designated Bridge Selection | Intermec 6710 guide

SECTION 4 " Configuration

Designated Bridge Selection

If the current designated bridge goes offline, the remaining candidates negotiate to determine which one becomes the new designated bridge.

Summary

In summary, the designated bridge:

"Physically connects to a secondary Ethernet LAN.

"Is within the radio coverage area of an access point on the distribution LAN.

"Has the highest nonzero bridge priority. If it has the same bridge priority as another access point, then it has the highest Ethernet address (unless the access point with the highest priority is out of radio range).

Status

The Status option determines if the access point can function as a designated bridge. Settings are:

	Enabled
	Disabled

Setting	Description

Enabled (default) This access point may function as the
	designated bridge for the secondary
	Ethernet LAN.
Disabled	This access point cannot be the designated
	bridge for the secondary Ethernet LAN.

The Disabled setting has the same effect as setting Bridge Priority to 0. The Disabled setting is valuable for debug.
