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.

This command shows SLPP Guard status about selected ports (ports option) or shows all ports that have been disabled by SLPP Guard (disabled-ports option).

Example

The following example shows SLPP guard status for ports 15, 16, 31, 61, and 62

# show slpp guard ports 15 16 31 61 62
