Cisco Catalyst 9800 How to configure 2 different SSID on the same vlan

[dsiin]

Hello,

We have a Cisco Catalyst 9800-L Wireless Controller in version 17.3.4c

I'm looking for create 2 WLAN (same SSID) for the same VLAN:

- WLAN broadcasted for location A -> VLAN 2
- WLAN no broadcasted for location B -> VLAN 2

When i try to use the same VLAN for another WLAN (SSID or Profile), i've this error:

How can i do this please?

thx

You can fix this using a generic name for the Policy Profile such as "corporatevlan0x" and then associatte the WLAN to the corresponding Policy Profile and map VLAN Id under the Flex Profile. This way you don't need to create single Policy profiles per site, and re-use the geenric one creating only Flex profiles and mappingthe different VLANs, hence reducing the length of the running config:

wireless profile policy LOCAL-CORP1
no central association
no central dhcp
no central switching
vlan corpnetvlan01
no shutdown
!
wireless profile policy LOCAL-CORP2
no central association
no central dhcp
no central switching
vlan corpnetvlan02
no shutdown
!
wireless profile flex SITE1-FLEX
central-webauth
no local-auth ap radius
native-vlan-id 1
vlan-name corporatevlan01
 vlan-id 32
!

wireless profile flex SITE2-FLEX
central-webauth
no local-auth ap radius
native-vlan-id 1
vlan-name corporatevlan02
 vlan-id 32
!

Hello,

Thank you for your reply, but i don't wan't to do Flex Wlan.

The 2 different location are on the LAN, but i need two almost same WLAN on the 2 location: 1 broadcasted and the second not broadcasted.

Exemple:
- Location A, SSID wifipro, mdp xxxx,, Vlan 32 

-  Location B, SSID wifipro, mdp xxxx, Vlan 32

And i don't know how to do that

You need to create a new SSID but with a different Profile Name.  This also means that you will have different WLAN ID's.  That will allow you to have the same SSID: wifipro and have one defined with broadcast enabled and the other profile with broadcast disabled.  So start there...

Exactly as @Scott Fella said - you're confusing re-using the VLAN ID with the WLAN ID.
You already said "create 2 WLAN" and those 2 WLANs must have different (unique) WLAN IDs (and profile names) but they can still use the same SSID and VLAN ID.
