Storm Control - config options / risk

r1127hyduk

To all,

We have seen an interesting anomaly over the past three months where Storm Control triggers a shutdown of an interface as configured.  The Storm Control configuration looks like the following;

storm-control broadcast level pps 2k 300

storm-control multicast level pps 4k 3k

storm-control action shutdown

 

Our interfaces constantly run around 2.82k and to 2.85k pps

Issue - we encounter 7 or 8 pairs of switches executing the shutdown command out of 18 pairs of switches on the same subnet.

 

Possible Resolution?

What parameters have others used for storm-control and what are the risks to increasing pps to 5k and 4k?

storm-control broadcast level pps 2k 300

storm-control multicast level pps 5k 4k

storm-control action shutdown

Thoughts and comments requested.  The team is reviewing applications and other aspects that could trigger these events.  Any comments or suggestions are welcome

Hi,

You can set it as a percentage of the interface bandwidth. Test and monitor again.

example:

storm-control broadcast include multicast
storm-control broadcast level 1.00

To verify config, use

show storm
