Not able to access controller using management interface

[wajahatkhan]

Dear All,

I configure IP address on the management interface port 1 of 5508 controller when i connect it direct to my laptop i can't ping or access controller from my laptop even i connect through layer 2 switch still i can't not.

IP Address of management interface : 10.21.0.50

Laptop IP Address : 10.21.0,51

You need to make sure that the manager interface is untagged. The vlan should be set to zero (0). Then you will be able to ping and access the WLC.

Thank for your reply...

Management interface is untagged and i can access using serive port but not through management interface

[Scott Fella]

Now best practice is to not connect you laptop to the WLC. You know that though... So eventually you will connect it to a switch and them you will want to actually tag the vlan. So if the WLC managing is on vlan 50 let's say, you will change the manager interface vlan to 50. Hope this helps:)

i tried this as well i connect my WLC to the through switch and i tag WLC interface to vlan 10 and also configured my switch interface which is connected to wlc to configured as vlan 10 and also my laptop in vlan 10 still not working

The port the WLC connects to should be a trunk port not an access port.

Please post the switchport configuration the WLC is connected to and the one your laptop is connected to. Don't forget the show interface summary from the WLC.

If your WLC is connected to a switch, you must make sure it's a gigabit switch. The WLC is only gigabit not 10/100/1000.

If you connect it to a switch, make sure it's a dot1q trunk port. Now connect your port on an access port assigned to that same vlan as the WLC manager interface is on.

Change your switch config to this

interface GigabitEthernet1/0/24
description *** connected to WLC ***
switchport mode trunk

Basically this is what you need to issue

config t
interface GigabitEthernet1/24
no switchport trunk native vlan 10

When you define the native vlan 10, you essentially are not tagging the vlan 10. So if you keep the native vlan 10 command, you need to change the manager interface vlan on the WLC to zero (0).
