Configuring SLPP Guard

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

SLPP Guard is disabled by default.

Procedure

  1. Enter GigabitEthernet Interface Configuration mode:

    enable

    configure terminal

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

    Note

    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.

  2. Enable SLPP Guard on the port:

    slpp-guard enable

  3. Optional: Configure the timeout value on the port:

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

Example

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

Variable definitions

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.
