CME with Linksys switch, will VOICE and DATA vlan still work?

[rammany19]

hello,

please i have a cisco CME router in a campus network and my config below:

Building A---------Cisco router (CME) with 3560 Switch

Building B----------Linksys Switch management

Building C---------Linksys Switch management

The buildings are connected to each other with a NanoStattion 5 AP

please how do i integrate everything to work? will i create the vlan on the linksys switch both voice and data?

You could make it work, but it may not be easy.  I don't know if the Linksys switches will pass CDP or not along.  They will not create CDP, but they might forward it.  You will need to have the Linksys switches having the same voice and data vlans on all of the ports.

If CDP is passed by the switches, then the phones will discover their VLAN and work fine.  If CDP is not passed, you will have to set the voice vlan on all of the phones manually.

Thanks, what of the trunking?

Nanostation is plugged to port fa0/8 , so i should configure trunking on the linksys?

what if the switch dont have a trunk encapsulation capability? how do VOICE and DATA tranverse the link?

Thanks

To get this to work the way I am describing, trunking will need to be on the ports.  If it doesn't work, then you could have problems with voice quality.  But, if trunking doesn't work, and CDP is passed to the phones, the phones won't register.  In that case, you would need to disable CDP on your cisco switch.  At that point, it would be voice and data on the same vlan.
