enable slpp guard

enable slpp guard ports [port_list | all]


Enables the Simple Loop Protection Protocol (SLPP) Guard feature.

Syntax Description

slpp Specifies enabling SLPP.
guard Specifies disabling a port as soon as an SLPP PDU is received.
ports Specifies selecting ports on which to enable SLPP guard.
port_list Selects which ports to enable SLPP guard on.
all Specifies enabling SLPP guard on all ports.


By default, SLPP Guard is disabled on all ports.

Usage Guidelines

SLPP is an application that detects loops in a Split Multi-link Trunking (SMLT) network. SLPP Guard is a complementary feature that helps prevent loops in networks by administratively disabling an edge port if a switch receives an SLPP PDU from an SMLT network.


The following example enables SLPP Guard on port 5:

# enable slpp guard ports 5
