Hi Friend,

When configuring the traffic storm control level, note the following:

•You can configure traffic storm control on an EtherChannel (a port channel interface).

•Do not configure traffic storm control on ports that are members of an EtherChannel. Configuring traffic storm control on ports that are configured as members of an EtherChannel puts the ports into a suspended state.

So you need not confiure on interfaces which are part of port channel and just need to configure on int port channel which you have already done.

Have a look at this link

HTH, if yes please rate the post.

Interfaces that are in the same channel group must be indentical in every way, configuration, speed/duplex, etc.

Dear ALL,

I had checked the config, i didnt put the storm control on each gi interface, only the port channel got the storm-control. In addition, all gi ports configuration are the same on both switches and trunks.

Hi Sam,

Yes only the port channel interface will have that config and if you try to put it on physical interface level you will get the physical interface in suspended mode.
