Configures the recovery timeout period for the Simple Loop Protection Protocol (SLPP) Guard feature.
| slpp | Specifies configuring SLPP. |
| guard | Specifies disabling a port as soon as an SLPP PDU is received. |
| ports | Specifies ports on which to configure the recovery timeout period. |
| port_list | Selects which ports to configure the recovery timeout period for (list separated by a comma or -). |
| all | Specifies configuring all ports with the designated recovery timeout period. |
| recovery-timeout | Specifies configuring the timeout period after which ports are re-enabled. |
| seconds | Designates the recovery timeout period in seconds after which the ports are re-enabled. Range is 10–65,535. Default is 60 seconds. |
| none |
By default, the recovery timeout period is 60 seconds.
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.
The following example configures the recovery timeout period to 600 seconds for port 9:
# configure slpp guard ports 9 recovery-timeout 600
