Cisco Virtual Wireless Controller cannot see access points
I just upgrade from ESX 4.5 to 6.7 and the controller can not longer see the access points. There have been some changes in ESX for the interfaces, but for some reason it is not working. (I can see one new difference is that the switch and the port can be configured for Promiscuous mode, I tried both but neither work)
Virtual Switch:
1. Allow promiscuous mode Yes
2. Allow forged transmits Yes
3. Allow MAC changes Yes
Data Port:
1. VLAN ID: 4095
2. Allow promiscuous mode Yes
3. Allow forged transmits Yes
4. Allow MAC changes Yes
Service Port
1. VLAN ID: 0
2. Allow promiscuous mode No
3. Allow forged transmits No
4. Allow MAC changes No
Switch Config:
interface GigabitEthernet0/1
description trunked port
switchport trunk native vlan 30
switchport trunk allowed vlan 21,30,31,40,41
switchport mode trunk
spanning-tree bpdufilter enable
ip dhcp snooping trust

Can you see the WLC's GUI/CLI? If not, can you post the output from:
show interface summary
...at the WLC CLI?
Which VLAN is the WLC management on?
Which VLAN are the APs on?

1. Yes, it was upgraded directly from 4.5 to 6.7.0 Update 3 (Build 15160138) using the HP custom image for a Gen 9
2. All VLAN settings were done according to Cisco Deployment guide: https://www.cisco.com/c/en/us/td/docs/wireless/technology/mesh/8-2/b_Virtual_Wireless_LAN_Controller_Deployment_Guide_8-2.html
3. The VLANs were also set this way on the older ESX system (I have around 10 of these in use on older version of ESX with no issues)
4. The data port VLAN is set to 4095 because it is a trunked port on the Cisco device.
5. The Service Port is set to no VLAN or 0 Per Cisco documentation
6. It still reports the image of the system as "ESX/ESXi 4.x virtual machine"
7. The Access Points are in VLAN 31, they receive IP addresses via DHCP and can ping the controller.
8. The controller can ping the access points as well.
9. The only port specific configuration for this scenario is having the native VLAN 30 assigned to the port for communications to the Service Port that is set to VLAN 0
10. There are no connectivity problems to the CLI or GUI

4095 is a special VLAN, which effectively means that the virtual machine will receive ALL traffic, and the VM will need to untag/tag the traffic on it's internal nic, e.g. Guest VLAN Tagging.
Does this happen in the VM?

ASKER CERTIFIED SOLUTION

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
You shouldn't have to upgrade the code on the APs for the WLC to see them. That's the job of the WLC. When an AP joins a WLC with a different software version, the AP will download the correct version from the WLC.
Are you sure it was 4.5 ? Maybe this is a typo ?
A few comments do you need to use promiscuous mode and VLAN 4095, and VLAN 0 ?
What is the data port virtual machine portgroup and what VLAN should it use ?
same with Service port ?
You have VLAN 21,30,31,409,41 coming into the switch ?
