Default

By default, the recovery timeout period is 60 seconds.

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.

On a port with SLPP Guard enabled, if an SLPP PDU is received, the port is immediately disabled. After the configured timeout value set by this command expires (associated with each port), the port is automatically re-enabled.

Example

The following example configures the recovery timeout period to 600 seconds for port 9:

# configure slpp guard ports 9 recovery-timeout 600
