    This could be due to the way SmartLink is designed. SmartLink will only kick in if ALL uplinks connected to a downstream switch port fail will the Nic be marked as down. So for example if you are using mapped VLANs and have connections up from either a single chassis or multiple chassis and have multiple uplinks, Say Port 1 going to SUS with VLAN 1,2 Port 2 going to SUS with VLAN 21,22. You have a server profile with VLANs 1,2,21,22 going to a blade. If the uplink from port 1 fails but the uplinks from port 2 are still working, VLANs 1,2 will stop working but not fail over as SmartLink won’t shut down the blade port as it still sees live connections from VLANs 21,22.
    No way round it othger than to have only single uplinks going to a blade.

      Indeed this is by design and I don’t have a document that says it is by design sadly :/. I figured it out when doing the high availability tests at the customer site, but now we know because I blogged about it :-P.

      Thank you for sharing your thoughts and knowledge.
