    Are you pinging from the second subnet?
    Is it a wired or wireless client?

    hi,

    it's a wire client.

    all IAPs and the virtual controller are in the same subnet.

    Can you share a show tech so we better know IP addressing gateway scheme used. Also provide IP of the wired client.

  • 6.  RE: can't ping IAP

    Posted Apr 14, 2017 03:58 PM

    1. Show tech from master IAP would be best attached as its huge. i think you got the show summary. show tech would have given more details e.g. software version, or any funny logs.

     

    2. From the shared information:

    VC IP Address :10.225.61.253

    VC VLAN :0
    VC Mask :0.0.0.0
    VC Gateway :0.0.0.0
    VC DNS :0.0.0.0

    Master IP Address *:10.225.61.101
    IP Address :10.225.61.101
    Netmask :255.255.255.0
    Gateway :10.225.61.254
    NameServer :8.8.8.8

     

    So you are able to ping 10.225.61.253 but not 10.225.61.101, from a PC in another subnet.

     

    Assuming this is the native / untagged VLAN (share VLAN number) on the ports leading to IAPs. Can you:

     

    a) make sure mask & gateway info is consistent on all devices.

    b) ping from gateway 10.225.61.254 to 10.225.62.101

    c) does SSH work to .253 and .101, from the network?
