Enable Simple Loop Prevention Protocol (SLPP) by port to detect a loop and automatically stop it.

Identifies the slot and port in one of the following formats:
a single slot and port (slot/port)
a range of slots and ports (slot/port-slot/port)
a series of slots and ports (slot/port,slot/port,slot/port)
all ports on the same slot (slot/all)
all ports on the switch (all)
Caution
Configure the rx-threshold above 50 ms only on lightly loaded switches. If you configure the rx-threshold to a value greater than 50 ms on a heavily loaded switch and a loop occurs, the system can experience high CPU utilization. The default is 1.
None
