Hello. Last Friday, for some reason, two IP Phone 7945's stopped forwarding VLAN IP's to PC's connected to it. Here's what we got: We have a Cisco 3750 with ports set up for VLAN 7 for IP Phones and VLAN 25 for Windows PC's. There are two IP Phones connected to this switch, each IP Phone has a PC daisy changed through it. For some reason, last Friday morning, the PC's lost connectivity, while the phones were working normally (can send/receive calls). I connected the PC's straight to two separate ports on the switch. That made the PC's work again! I connected my laptop to the phone, and I couldn't get an IP address from their either.
What could be wrong with thw switch? As far as I know, no one made any configuration change on the switch.
