Configure SLPP Guard

Configure SLPP Guard on MLT and LAG ports to provide additional network loop protection.

SLPP Guard is disabled by default.

Procedure

Enter GigabitEthernet Interface Configuration mode:

enable

configure terminal

interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]}

Note

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

slpp-guard enable
Optional: Configure the timeout value on the port:

slpp-guard timeout {<10-65535> | 0}

Switch:1(config-if)#slpp-guard enable
Switch:1(config-if)#slpp-guard timeout 120

Use the data in the following table to use the slpp-guard command.


Variable	Value
timeout `<0 \| 10–65535>`	Specifies the time period, in seconds, for which SLPP Guard disables the port. After the timeout period expires, the switch reenables the port. The timeout value can be 0 or a value ranging from 10 to 65535. With a value of 0, the port remains disabled until it is manually re-enabled. The default timeout value is 60 seconds.
