Advanced Traffic Management Guide K/KA/KB.15.15

Example 96 Loop protection enabled in preference to STP
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 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.
If loop-protect is enabled in port mode, it cannot also be enabled in VLAN mode, and
vice-versa.
