Operating notes

  • The receiver-action option can be configured on a per-port basis and can only be enabled after loop protection has been enabled on the port. All other configuration options (disable-timer, trap loop-detected, and transmit interval) are global.

  • The trap option refers to an SNMP trap.

  • Regardless of how the receiver-action and trap options are configured, all detected loops will be logged in the switch's event log.

  • The no loop-protect port command will not remove a receive-action configuration line from the running configuration unless this option is set to receive-action send-disable.

  • If loop-protect is enabled in port mode, it cannot also be enabled in VLAN mode, and vice-versa.
