urgent-- could cisco uc320 work with dumb switch ? how to configure

[apple0007]

could cisco uc320 work with dumb poe switch, with its voice vlan alway in 100, I can't change it, and my phone can not find the pbx through the switch, if it can, how can I configure it.

Hi Rex,

If the switch is unmanaged the 802.1q (tagged) ethernet frames typically pass right through the switch as if the phone was directly connected to the UC320W.  In this case both voice VLAN works and data VLAN. I would guess that if a switch has PoE that it is a managed switch though.  If it is a managed switch you will need to configure ports, vlans, and possibly CDP passthrough.
