Ethernet Configuration
• 10-Base-T / Half Duplex—Ethernet network connector for 10-Mbps transmission speed over
twisted-pair wire and operating in half-duplex mode.
• 10-Base-T / Full Duplex—Ethernet network connector for 10-Mbps transmission speed over
twisted-pair wire and operating in full-duplex mode.
• 100-Base-T / Half Duplex—Ethernet network connector for 100-Mbps transmission speed over
twisted-pair wire and operating in half-duplex mode.
• 100-Base-T / Full Duplex—Ethernet network connector for 100-Mbps transmission speed over
twisted-pair wire and operating in full-duplex mode.
Loss of Backbone Connectivity # of Secs (1-10000)
This setting specifies the amount of time the access point has before it takes action when it detects a loss
of backbone connectivity (such as a loss of Ethernet link and no active trunks available on its radio). The
action the access point takes is specified in the Loss of Backbone Connectivity Action setting, described
in the next section.
Loss of Backbone Connectivity Action
This setting determines the action the access point takes when a loss of backbone connectivity occurs
after the time specified in the previous setting. The following actions can be taken:
• No action—nothing is done.
• Switch to repeater mode—the access point disassociates all its current clients and becomes a
repeater while its backbone connectivity is lost. The access point attempts to communicate with
another root access point using the infrastructure SSID. If it establishes a connection, clients can
associate with the root access point through this repeater to maintain connectivity to the backbone
LAN. If an appropriate root access point is not found, no clients can associate to this access point.
• Shut the radio off—the access point effectively removes itself from the infrastructure by
disassociating its current clients and not allowing further associations until backbone connectivity
is restored.
• Restrict to SSID—the access point disassociates all its current clients and switches to use the SSID
configured in the Loss of Backbone Connectivity: SSID setting. After this action is taken, only a
client using the specified SSID can associate with the access point, allowing an administrator to
perform failure recovery or diagnostic procedures.
Loss of Backbone Connectivity SSID
This setting specifies the SSID used by the access point if the Loss of Backbone Connectivity Action
setting is set as Restrict to SSID and backbone connectivity is lost for longer than the time specified in
the Loss of Backbone Connectivity: Number of Seconds setting.
The setting also defines an administrator-only SSID an administrator uses to communicate with the
access point for diagnostic and failure-recovery purposes.
If VLANs are active on the access point, the SSID names are displayed in the Loss of Backbone
Connectivity SSID field.
Note When backbone connectivity is restored, the access point restores itself to the settings established during
normal operation.
