OS 6900-X20 connectivity with WLAN Controller 4450

[yasirsattar06]

Dear All,

I need your help on subject matter as i am new on Alcatel Data.

I have a 6900 Switch and 4450 Controller. I have to connect these two through Fiber (SFP-GIG-SX Transceivers). As per my knowledge, Alcatel switches run STP 1x1 by default and 4450 Controller does not have 1x1.
How these two will be connected?

I have configured 4 Vlans on 6900 with IP Interfaces.
ip interface "voice" address 192.168.10.254/24 vlan 10
ip interface "data" address 192.168.20.254/24 vlan 20
ip interface "wireless" address 192.168.30.254/24 vlan 30
ip interface "mgmt" address 192.168.40.254/24 vlan 40 (Management VLAN)

mgmt vlan is configured on all Edge Switches. Connectivity between End Clients is fine.
Access Points are connected to the Edge Switches and configured in Vlan 30.

How OS6900 and WLC 4450 will be configured for communication.

Kind Regards,
Yasir

Did you have 4 parallel connections (one per vlan)? than you can activate at switch pvst+ compatiblity and also at controller. This is also a good choice if you have only one connection.
Other way is to create a linkagg (LACP) at both sites and tag all the vlans.

Dear Silvio,

Currently i am planning to connect with single uplink. But i have option to connect with 2 uplinks for Redundancy purpose.

Kind Regards,
