LBD Configuration

Configuring Global
Settings for LBD
Use the Administration > LBD (Configure Global) page to enable loopback
detection globally, specify the interval at which to transmit control frames, the
interval to wait before releasing an interface from shutdown state, the response to
a detected loopback, and the traps to send.
Parameters
These parameters are displayed:
◆ Global Status – Enables loopback detection globally on the switch.
(Default: Enabled)
◆ Transmit Interval – Specifies the interval at which to transmit loopback
detection control frames. (Range: 1-32767 seconds; Default: 10 seconds)
◆ Recover Time – Specifies the interval to wait before the switch automatically
releases an interface from shutdown state. (Range: 60-1,000,000 seconds;
Default: 60 seconds)
If the recover time is not enabled (checkbox unmarked), all ports placed in
shutdown state can be restored to operation using the Release button. To
restore a specific port, re-enable Admin status on the Configure Interface page.
The recover-time is the maximum time when recovery is triggered after a loop
is detected. The actual interval between recovery and detection will be less
than or equal to the recover-time.
◆ Action – Specifies the protective action the switch takes when a loopback
condition is detected. (Options: None, Shutdown; Default: Shutdown)
■
None - No action is taken.
■
Shutdown – When the response to a detected loopback condition is set to
shut down a port, and a port receives a control frame sent by itself, this
means that the port is in looped state, and the VLAN in the frame payload is
also in looped state. The looped port is therefore shut down.
◆ Trap – Sends a trap when a loopback condition is detected, or when the switch
recovers from a loopback condition. (Options: Both, Detect, None, Recover;
Default: None)
■
Both – Sends an SNMP trap message when a loopback condition is
detected, or when the switch recovers from a loopback condition.
■
Detect – Sends an SNMP trap message when a loopback condition is
detected.
■
None – Does not send an SNMP trap for loopback detection or recovery.
■
Recover – Sends an SNMP trap message when the switch recovers from a
loopback condition.
