Do I have to deploy a active-gateway setup on a VSX pair in order to ping/access the individual pair members?

    Hope someone can help, I'm sure there is a quick fix for my road block.

    I'm setting up multi-chassis lag connections to a series of downstream 6300m switches from my new VSX pair

    I'm not using my vsx pair as a routing switch, I just want to provide layer 2 trunk access as I have a separate upstream routing core switch

    Do I have to incorporate vlan active-gateway in order to provide Layer 2 access to the downstream devices on the multi-chassis lags?

    I currently cannot ping my downstream switches that are on lags.  I noticed too that I can not ping the secondary 8360 switch from one side of my ISL link to the other side from the primary 8360 switch.  I currently only have the primary connected to the rest of the core network via a single access port while setting up and testing. The VSX ISL connection is functioning properly however.

    Lacp says the two multi-chassis lags that I've currently connected are up and forwarding.

    I'm just wondering what I'm missing in the configs. Here are the attached running configs from the Primary 8360 and one of the 6300 units:

    If anybody has any suggestions it would be appreciated.

    Hi, 

    Update your 6300M Uplink configuration as below by allowing VLAN1

    interface lag 5

        no shutdown

        description Trunk VSX LAG

        no routing

        vlan trunk native 1

        vlan trunk allowed 1, 25,100,131,187,204-205,3216,3224,3253

        lacp mode active

    or

    interface lag 5

        no shutdown

        description Trunk VSX LAG

        no routing

        vlan trunk native 1

        vlan trunk allowed all

        lacp mode active

    Thanks NHN

    Even after running the show vlan command and not seeing the native vlan on my lags I was still stumped until you posted your reply. I would have been here for days before catching that.

    Thanks alot
