ETECTION

Use the Spanning Tree > Loopback Detection page to configure loopback 

detection on an interface. When loopback detection is enabled and a port 

or trunk receives it’s own BPDU, the detection agent drops the loopback 

BPDU, sends an SNMP trap, and places the interface in discarding mode. 

This loopback state can be released manually or automatically. If the 

interface is configured for automatic loopback release, then the port will 

only be returned to the forwarding state if one of the following conditions is 

satisfied:

◆

The interface receives any other BPDU except for it’s own, or;

◆

The interfaces’s link status changes to link down and then link up again, 

or;

◆

The interface ceases to receive it’s own BPDUs in a forward delay 

interval.

N

OTE

:

 If loopback detection is not enabled and an interface receives it's 

own BPDU, then the interface will drop the loopback BPDU according to 

IEEE Standard 802.1w-2001 9.3.4 (Note 1).

N

OTE

:

 Loopback detection will not be active if Spanning Tree is disabled on 

the switch.

N

OTE

:

 When configured for manual release mode, then a link down/up 

event will not release the port from the discarding state.

ARAMETERS

These parameters are displayed:

◆

Interface

 – Displays a list of ports or trunks.

◆

Status

 – Enables loopback detection on this interface. 

(Default: Enabled)

◆

Trap

 – Enables SNMP trap notification for loopback events on this 

interface. (Default: Disabled)

◆

Release Mode

 – Configures the interface for automatic or manual 

loopback release. (Default: Auto)

◆

Release

 – Allows an interface to be manually released from discard 

mode. This is only available if the interface is configured for manual 

release mode.
