Hi gurus,
I am using the startup utility to configure LAG on a 5508 to connect to 3560G switch. i have tried to use 7.0, 7.4, 7.5 but I just can't get it up, however I can get it connected using access port. I notice the light on the first port is always off, i can't find an option to configure the STP on the wlc 5508, i tried to follow the documentation but to no avail, I would really appreciate help here. Thanks a lot.
I have the below on the switch :
interface Port-channel32
description LAG port connected to BA-C-WLC03
switchport trunk encapsulation dot1q
switchport trunk native vlan 30
switchport mode trunk
spanning-tree portfast
!
interface GigabitEthernet0/1
switchport trunk encapsulation dot1q
switchport trunk native vlan 30
switchport mode trunk
channel-group 32 mode on
spanning-tree portfast
and the WLC 5508:

Hi,
Disable LAG, and connect to a single trunk switch port, would port 1 go up?
also, you can check the switch port statistics if there are any packets from the WLC port 1.
08-03-2013 10:13 PM
Are you making changes which makes the WLC loose connectivity? Try putting the WLC in a new vlan or a different vlan to test. You already found a bad switchport so I would test on a different switch also.

Your sfp's working fine? I would just connect one port at a time and test... so for example... connect only wlc port 1 to i'm guessing GE0/2 and see if that works. Then disconnect that and only connect wlc port 2 to GE0/3 and so on. Just doesn't seem right unless it something wrong with the switch.
Thanks,
Scott

Okay... as long as you can test everything out on the switch side it would be easier... as I have to assume things are all working. The thing is, you can setup the switch ports all in a etherchannel and connect only one port on the WLC and it should work. Now if you connect two and it fails, then we hav an issue somewhere.
Can you post your show run-config no ap

Hi Scott,
Adminmode is enabled, but the port is still down despite rebooted, actually I have 3 units of 5508 all having port 1 down, and LAG won't formed, i have tried to connect to a 4500 switch as well.

Remove the native vlan and tag the vlan in the WLC.

That's weird because if its all 3 WLC's. your saying if you set the port to an access port the WLC port comes up? Or is the port always down.
Since this seems like a new install, can you factory reset the WLC and then tag the vlan and leave lag as default. Also the service port isn't connected to the network correct. Don't enable HA also when you are in the startup wizard.

Can you also capture your input when your going thought the wizard.

Hi Scott,
Attached is the log after resetting to factory default. I didn't enable HA, the service port is not physically connected.
As with port 1, I found out that the error is from the switch, the interface is lid and fowarding, but doesn't work, it works after i swap the port.
However, the LAG still doesn't work.

Hi Scott,
There is also a very strange behaviour that each time when the WLC is reset to factory default, it will stay connected to the switch for a period of time, after that the connectivity is gone.
I added a static mac to the switch, and I was able to ping for a while so far so good..
I am able to ping from the switch to the WLC, however not from WLC to switch or from the connected notebook to the WLC.
BA-1F-C-CS01#ping 10.200.130.11
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.200.130.11, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/4/9 ms
(Cisco Controller) >ping 10.200.130.1
Send count=3, Receive count=0 from 10.200.130.1
this is an initial setup, so both devices are connected directly, no firewall or anything in between.

Paul

Are you making changes which makes the WLC loose connectivity? Try putting the WLC in a new vlan or a different vlan to test. You already found a bad switchport so I would test on a different switch also.

Hi Scott,
The switch is a second one I used, it is a blank switch to test this out. i change the vlan anyway but no go. i will look for another one to try....
Why it gets connected only when i factory reset it? but only for a while.
append below the only config on the switch:

This is the interface that the wlc connects to correct? Any you only have one port on the WLC connected to that port? You must also have the WLC managment interface set to vlan tag of 0 which is untagged for this to work, correct?

Scott

Hi Scott,
interface gi0/1 is not in use after I detected a problem in it. the management interface has been set to tagged 30 or 0 alternating with the switch, it will only works after a factory reset.
The WLC has 5 physically connected ports ranging from port 1 - 5 connecting with the 3560 switchport ranging gi0/2-6.
