I recently ran across an issue where the storm-control that was configured on my port-channel interfaces caused the physical interfaces to go into a suspended state. Hardware: 3 stacked 3850 (IOS XE release 3.7.3E) access switches connecting to a Juniper legacy core and a new 6807-XL core
I ended up removing storm-control on both port-channels because I was working in a limited window of time (cutover) and the link lights turned green and started passing traffic. I haven't been able to find much about this regarding why the interfaces went into a suspended state, as this is not the default behavior of storm-control or etherchannel (to my knowledge). Also, interfaces Gi2/1/1 (to 6807) and Gi2/1/2 (to legacy) were not connected because not enough fiber was ran to accommodate this, but it is anticipated to happen in the future. So, I'm not sure if that has something to do with it:

Any insight as to why Gi1/1/1 and Gi1/1/2 were in a suspended state because of storm-control would be appreciated. Thanks in advance. |
