Configure SLPP packet-rx on a Port
Enable SLPP by port to detect a loop and automatically stop it.
Important
To provide protection against broadcast and multicast storms, as a best practice, enable Rate Limiting for broadcast traffic and multicast traffic.
Procedure
Example
Switch(config-if)#slpp port 1/1 packet-rx-threshold 5
Variable Definitions
Use the data in the following table to use the slpp port command.
Variable |
Value |
---|---|
<1-500> |
Specifies the SLPP reception threshold on the ports, expressed as an integer. The packet reception threshold specifies how many SLPP packets the port receives before it is administratively disabled. To set this option to the default value, use the default operator with the command. The default value is 1. Note:
As a best practice, configure the rx-threshold above 50 slpp packets only on lightly loaded switches. If you configure the rx-threshold to a value greater than 50 on a heavily loaded switch and a loop occurs, the system can experience high CPU utilization. |
