Loop Protection
N o t e s
■
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 a 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.
