Configuring SLPP packet-tx on a VLAN

Enable SLPP by VLAN to detect a loop and automatically stop it. This configuration controls the boundary of SLPP-PDU transmission.

Important

Important

To provide protection against broadcast and multicast storms, as a best practice, enable Rate Limiting for broadcast traffic and multicast traffic.

Procedure

  1. Enter Interface Configuration mode:

    enable

    configure terminal

    interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]} or interface vlan <1–4059>

    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:

    slpp enable

  3. Configure the transmission interval:

    slpp tx-interval <500–5000>

  4. Add a VLAN to the transmission list:

    slpp vid <1-4059>

Example

Log on to the VLAN Interface Configuration mode:

Switch(config)# interface vlan 2

Enable SLPP:

Switch(config-if)# slpp enable

Configure the transmission interval to 500 milliseconds:

Switch(config-if)# slpp tx-interval 500

Add a VLAN, with the VLAN ID of 2, to the transmission list:

Switch(config-if)# slpp vid 2

Variable Definitions

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

Variable

Value

enable

Activates or disables the SLPP operation.

You must enable the SLPP operation to enable the SLPP packet transmit and receive process.

If you disable the SLPP operation, the system sends no SLPP packets and discards received SLPP packets.

To set this option to the default value, use the default operator with the command. The default is disabled.

500–5000

Configures the SLPP packet transmit interval, expressed in milliseconds in a range from 500–5000. The default value is 500. To set this option to the default value, use the default operator with the command.

<1-4059>

Adds a VLAN, by VLAN ID, to a SLPP transmission list. Use the no operator to remove this configuration.
