Configure the SLPP by Port
Before you begin
-
Enable SLPP globally before you configure it on a port.
About this task
Use SLPP on a port to avoid traffic loops on the port.
Note
To provide protection against broadcast and multicast storms, as a best practice, enable Rate Limiting for broadcast traffic and multicast traffic.
Procedure
- In the navigation pane, expand .
- Select SLPP.
- Select the Ports tab.
- Double-click PktRxThreshold for the desired port to edit the threshold value for packet reception.
- Double-click SlppEnable for the desired port.
- Select true to enable SLPP.
- Select Apply.
Ports Field Descriptions
Use the data in the following table to use the Ports tab.
Name |
Description |
---|---|
IfIndex |
Specifies the interface index number for a port. |
PktRxThreshold |
Specifies the threshold for packet reception. Configure the SLPP packet receive threshold to a value (1- 500) that represents the number of received SLPP-PDUs to shut down the port. This variable is a port-level parameter, therefore if the port is tagged, SLPP-PDUs from the various VLANs increment this single threshold counter. The default is 1. |
SlppEnable |
Activates SLPP on the selected interface. The default is disabled. |
IncomingVlanId |
Shows the VLAN ID of the classified packet on a port disabled by SLPP. |
SrcNodeType |
Specifies the source node type of the received SLPP packet. |
PktRxCount |
Shows the total number of SLPP packets the port received. |
TimeToClrPktRxCount |
Specifies the timer to clear the SLPP receive counter. After you enable SLPP and the port receives SLPP PDUs, the timer starts. After the timer exceeds the configured value, the system resets the count to zero. The default is 21,600 seconds. |
RemainingTimeToClrPktRxCount |
Shows the time remaining before the SLPP receive counter is reset to zero. |
