Configuring Loopback Detection
Parameters
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.
• Action – Sets the response for loopback detection to block user traffic or shut down the
interface. (Default: Block)
• Shutdown Interval – The duration to shut down the interface. (Range: 60-86400 seconds;
Default: 60 seconds)
If an interface is shut down due to a detected loopback, and the release mode is set to “Auto,”
the selected interface will be automatically enabled when the shutdown interval has expired.
If an interface is shut down due to a detected loopback, and the release mode is set to
“Manual,” the interface can be re-enabled using the Release button.
