WIFI does not work after connecting POE switch

  • 1.  WIFI does not work after connecting POE switch

    Posted Jan 15, 2014 05:28 AM

    This is the situation:

     - I have 3 Aruba instant AP's, all connected to an POE switch (which is manageble for VLAN's)

    - From the POE switch I have a cable (port 10) to my firewall (port 14)

    - On my firewall on port 14 I have configured 3 VLAN's. Each VLAN created is for another SSID that I set up in my aruba, so

        - SSID: Teachers (VLAN: 90), IP's: 10.0.90.x

                       Students (VLAN: 100, IP's: 10.0.100.x

                          .....

     

    When connecting to an WIFI (teachers of students), I do not get an IP from my DHCP-server.

    When I connect an AP without the POE switch on my firewall, everything goes fine. The problem is the POE switch.What do I have tot configure in my POE switch, so everythig will work?

     

    thx

    A few questions

     

    - Did you create those VLANs on the switch?

    - Is the link from the firewall to the switch a routed port or switchport?

         - If it is a routed port, did you add subinterfaces for each VLAN?

         - If it is a switch port, is it configured as a dot1q trunk will all VLANs tagged?

    - Are the links to the IAPs configured as trunks?

    - Does the switch support GVRP?

    Are you using the same VLAN/Segment when you connect the IAPs to the switch as when you connect the IAPs to the firewall ?

     

    On your switch do you have ip helper address configured ?

    I dit not made the VLAN's in the switch. Now I dit (I think), but it is still not working. (Without the switch, it works fine, but as soon I connect the AP's to the switch, it doesn't work. So it had to be witch the settings of the POE-switch) . I'm kind a noob in the POE-switch settings...

    Problem solved. I changed everything from untagged to tagged (except the default VLAN) and it works...
