4404 interface issues

Unanswered Question
Jul 18th, 2007

I am experiencing a strange issue.

My management interface is up and working fine. If I then add an interface for another vlan, whenever I am hard connected to that vlan i cannot hit my management ip from that vlan it is not reachable.

I can still reach management from any other vlan. If i go to the ip of the interface i added in the vlan, then I can reach and ping the management interface ip again for a little while.

any ideas would be appriciated. I have not seen this at any of my other locations. I didnt install the LAN at this site though, just the controllers.

Delete and readd the VLAN and make sure DHCP server is configured right.

Is your Service port IP address overlapping with any of your other IP's?

Hi.

Maybe i have the same problem!

WLC4402-25, FW:4.0.

My management interface ist up (untagged)(192.168.1.x). My PC is on VLAN2(192.168.2.x).

If i add an interface (Name:VLAN2, VLANID:2, 192.168.2.x) then i can?t reach the controller any more. No SSH,no HTTP, no telnet. If i delete the interface named VLAN2 the everything works fine! I have no idea what the problem is. Maybe its a network problem?

Edit: Ther are no IP conflicts in the network.

Edit2: I connected to the above mentioned VLAN2 with my laptop, got an ip adress out of VLAN2(192.168.2.x) and i can conntect to the WLC with putty and ssh. But on my PC which is also in VLAN2 i cant connect?????

If I read you correctly, you are on wired VLan2 and you are trying to configure a wireless vlan2 on your controller at the same time. I don't think you can't do it - will obviously not. When you configure vlan2 on your WLC it's for the wireless clients not the wired clients. I have never tried to configure a wireless vlan the same as a wired vlan.

Hi have the same comportement, and i found one issue, not a very good issue, but an issue .....

When your PC is in VLAN2, you try to connect in ssh or https to the controler with the WLC IP oin vlan2 (192.168.2.x) and ... it's not work-> ok, immedialtly after you try to connect to the WLC with the IP in 192.168.1 and now it's working.

Have you restricted allowed VLans on the switch's trunk directly connected to your WLC? Is the WLC connected to a trunk port on the switch?
