slpp (for a port)

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

Syntax

Command Parameters

{slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]}

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)

If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.

packet-rx
Enables or disables SLPP packet reception on the port. The default is disabled.
packet-rx-threshold <1-500>
Specifies the SLPP reception threshold on the ports, expressed as an integer. The packet reception threshold specifies the number of SLPP packets the port receives before it is administratively disabled.
Caution

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.
