    Hi all,

     

    I have same strange issues in my network from time to time.

    I have an environment with a M3 controller and 240 AP-61, and I have a specific vlan for ap´s. The AOS version is 6.1.3.9

    The problem is that suddenly, I can´t see my ssid and if see the controller, I have all my access points down, except one of them.

    Then I look at the switch where this access point is connected and I can see that the port is showing to me three mac address.

    I only should see the access point mac.

     

    SWITCH#sh mac address-table | include 4/0/47
    100 AP-MAC-ADDR DYNAMIC Gi4/0/47
    100 0218.0a03.9f80 DYNAMIC Gi4/0/47
    100 02b5.a903.9f80 DYNAMIC Gi4/0/47

     

    If I shutdown this port. all access point become up and it begins to work correctly.

     

    Any ideas?

    Thanks

    Is that switch port configured any differently than the other AP ports?

    Hi,

     

    this port has the same configuration than the other ports. In fact, I forgot to mention that this problem has happened with different access points and it happens in a random way.

    In this case, all access points are connected to switch ports in access mode to specific vlan.

     

    Thanks

    When you're not experiencing problems I assume you are only seeing one MAC address per port right?
    Have you traced those MAC addresses to see what the devices are? Are they wired or wireless devices?

    Hi,

     

    It is correct. When it is working without problems, I only see the access point MAC address in the switch.

    As a matter of fact, I´ve not seen these mac address in the switch "mac address table" or in the controller "user-table".

    These mac address are not well known vendor mac addresses and is for that I can´t trace these devices,

    I disable this port, and when I enable the port again, these mac addresses have disappeared and all access point have recovered.

     

    Thanks
