Solved: From 8.0 code it is mandatory

chandogetrude · ‎06-10-2017

We have implemented a scenario in which WLC management Interface is in vlan 1 subnet but when we tag management Interface with vlan 1 we cannot reach the WLC management IP. The WLC is connected to 4506-e VSS chasis trunk ports.

When we untag the management interface i.e VLAN ID=0 we can reach the WLC but cannot configure SSO redundancy getting Error “please configure redundancy management vlan before enabling redundancy”

Please advise can we achieve the SSO setup in the said scenario

The firmware version in two WLC is 8.2.141.0

Prateek Saxena · ‎06-12-2017

From 8.0 code it is mandatory to tag the management vlan. From the output you have provided you have management untagged:

management LAG untagged 10.149.80.250 Static Yes No

you need to provide a vlan id there. If you have vlan 1 as native vlan on the switch trunk link, make any other vlan as native and tag the management vlan with id 1 using the command "config interface vlan management 1"

Post the output to the following commands:

WLC: sh sysinfo;
WLC: sh lag summary; and
WLC: sh interface summary
Switch: sh interface <TRUNK>; and
Switch: sh etherchannel summary

Note: While this entire setup is still in shambles, please have a good think about using VLAN 1.

Bootloader Version............................... 1.0.1

Kindly read Prateek's response (above).

And please upgrade the bootloader to 1.9.0 (recommended).

Scott Fella · ‎06-10-2017

Like Leo mentioned you should look at using another vlan. However, if you really need to tag vlan 1, then you need to issues this command on the switch:

vlan dot1q tag native

This will tag vlan 1 or any of your native vlans you defined on the switch. Make sure you don't break any uplinks when doing this.

From 8.0 code it is mandatory to tag the management vlan. From the output you have provided you have management untagged:

management LAG untagged 10.149.80.250 Static Yes No

you need to provide a vlan id there. If you have vlan 1 as native vlan on the switch trunk link, make any other vlan as native and tag the management vlan with id 1 using the command "config interface vlan management 1"

manvik · ‎12-16-2021

Thanks, we too had same scenario with VLAN 1, for the SW int gave some other VLAN as native and added VLAN 1 in trunk list.

Note, when you enable SSO in WLC, your WLAN interfaces would get changed to management. You'll have to change it to SSID interface, else you might not get connected.
