x440-48p-10G flashing ports

[dj_mcadams]

Have a stack of six x440-48p-10G with one x440-48p-10G trunked off of it. All ports on the stack (except switch 1 and 2) are flashing rapidly as if there is a loop, however I cant see any loops through the log or ELRP and network wise everything is working normally (although slow routing between vlans).

Hey Paul, not sure when this started, a show port sharing does not show anything and we are not using lacp. The trunk ports are flashing on both sides as well. Thanks

Hey DJ

When did this start? When you do a show port sharing does it show up? are you using LACP? what is happening to the ports on the switch that is trunked off the stack?

Thanks
