  • 1.  Can not connect to master controller

    Posted Jun 18, 2013 08:53 AM

    My Customer changed out there network switches last night.  You can ping all IAP's but 1.  Can not reach the VC, or connect to any of the IAP's via browser.

     

    Clients are connecting and working.

     

    Any thoughts?

    How are the IAP getting their IP addresses ? DHCP or Static ?

    You should probably make sure that there's no ip conflict with any other device if you are not excluding those static IPs

    Is the switch serving as the DHCP server ?

    The IAP 105's are on a Native management VLan and passing DHCP to a DHCP server per VLAN.

    Have you checked the arp tables on the switch(es) that the IAPs are connceted to? That would be a good way to see if the arp entries are present and in the right VLAN.

    We removed the 170.x.x.38 from the network.  Once we did that the AP's held an election and the VC came back online.
