Campus Access Point with two ethernet cables going to different switches on separate IDFs

    Hello Airheads friends.

    Has anyone installed a Campus Access Point with two ethernet cables on different switches on separate IDFs? My goal is to have a fully redundant environment.
    I believe if this environment works the AP will be powered by a single port and in case of switch #1 failure, the AP will restart and go up through the second port. Am I correct? Do you see any contraindications in this scenario?

    Thanks,

    Hi Guarana,

    I have never do it, but I believe you have to keep in mind the following points:

    1. Both switches have to behave as a single switch, because the AP will use both ports as a link aggregation. If they are on separate IDFs and a physical stack is not an option, you can use a virtual stack, such as VSF or alike.

    2. About the power it depends on the AP model you choose, For example, the AP-510 series datasheet says: "The AP supports direct DC power and Power over Ethernet (PoE; on port E0)". In this scenario, if the switch which is connected to the AP's E0 fails, the AP will go down though the other switch is still up and running.

    Maybe someone with practical experience on this can shed some more light on this.

    I honestly think per port it is cheaper to provide overlapping AP RF  coverage.

    Thank you Cjoseph and FJulianom

    I will run two cables to the same IDF and connect them to different members on the same switch stack.

    That sounds good. Configure the two ports on the stack as a link aggregation, the AP will configure its ports automatically.
