Configuring SLPP
Enable the Simple Loop Prevention Protocol (SLPP) globally and for a VLAN to detect a loop and automatically stop it. The VLAN configuration controls the boundary of SLPP-PDU transmission.
Procedure
Example
Enable SLPP:
Switch(config)# slpp enable
Configure the transmission interval to 5000 milliseconds:
Switch(config)# slpp tx-interval 5000
Add a VLAN, with the VLAN ID 2, to the transmission list:
Switch(config)# slpp vid 1
Variable Definitions
Use the data in the following table to use the slpp command.
Variable |
Value |
---|---|
enable |
Enables 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. |
