StormControl on Trunk interface?

[SIMMN]

Hey, All

I am facing some come-and-go broadcast storm on my network. Here is the story: I got report from end-users, who connect back to main office through ISP MPLS fibre network, saying they had some server disconnection and were experiencing slow Internet. However I did not really found anything on switches. I called ISP and they told me there was broadcast storm captured on their edge switch. But I did not capture anything even I configured stormcontrol on all the access ports.

The interface on my switch connecting to ISP is configured as a trunk interface for carry multple VLANs to remote office. So my question is should I enable stormcontrol on Trunk interface?

Put it on the physical interfaces first.

you can choke of exessive broadcasts there.

If yo storm-control the trunks, you won't get much to tell you root cause

I have the stormcontrol enabled on pretty much every access port. But there are several HP switches connected to Trunk port, which I am not sure how to monitor for broadcast storm. This is why I am wonder if I should enable stormcontrol on trunk port.
