In 4402 we have two port, I am using port -1 for management 172.16.124.10 [ vlan 1], do I use the same port -1 for VLAN 101 also for IPT Voice network [ 172.16.125.10] as trunk configured in switch or do I use only port-2 for other vlan configuration.
Port -1 is reseverd for management alone or do we can use port -1 for management + other vlan configuration.
Following the below doc for VLANs on Wireless LAN Controllers Configuration:
"0" assumes untagged and as such your switch will need to be native for that vlan. Any other number used will be tagged and as such a trunk needs to be appllied to the switch .q.
Why? That is a great question and one i have had as well. I have asked many Cisco engineers and the anwser i got was,"its recommend pratice. BUT you can tag the traffic".
Personally, I have deployments set up each way and I havent had any issues.
I hope that helps a little ...
If memory serves me correct, default VLAN for the WLC is "0" which is VLAN 1 on a switch. Can you turn Management interface to VLAN "0" on the WLC?
