Chapter 5: Configuring the Spanning Tree

Table 42. Spanning Tree Parameter Descriptions (Continued)

Parameter	Explanation
Rightmost LED	Choosing Spanning Tree Root Indicator causes
Behavior	the LED to blink if the access point is configured
	as the root and remain on if an error is detected.
Enable Ethernet	Determines how frames from end devices are
Bridging	moved between the wired and wireless networks.
	For more details, see “About Ethernet Bridging/
	Data Link Tunneling” on page 134.
	Check this check box if you want frames to be
	forwarded directly to the Ethernet network. Allied
	Telesyn recommends that you enable this
	parameter on all access points.
	Clear this check box if you meet the selection
	criteria listed in “About Ethernet Bridging/Data
	Link Tunneling” on page 134 and you want to use
	data link tunneling.

		Note
		If you enable this parameter on the root or
		designated bridge, but you disable it on all
		other access points on the same IP subnet,
		then Ethernet bridging is disabled on the IP
		subnet. This means that data link tunneling
		is enabled on the IP subnet.
Secondary LAN	Determines when this access point can become
Bridge Priority	the designated bridge in a secondary LAN. The
	access point that meets all the other
	requirements and has the highest secondary LAN
	bridge priority becomes the designated bridge.
	The secondary LAN bridge priority can be a value
	from 0 to 7. If you set this value to 0, the access
	point can never become the designated bridge.
	For help deciding if this access point should
	become the designated bridge, see the selection
	criteria listed in “About Secondary LANs and
	Designated Bridges” on page 132.
