I want to replace our 3Com superstack switches with a Cisco 4507. We have a 3COM NBX v3000 VoIP system with the 3Com 3102 business phones. The 3Com was configured to use vlan 1 for data and vlan 250 for phones. In the Cisco switch I used vlan 10 for data and vlan 50 for the phones. I setup DHCP for the phones on the cisco swtich, configured option 184 per the 3Com admin guide, enabled the dhcp service. When I plug the phones in the sit at the "Wait for NCP" status message.
I've implemented the Cisco switch for our data and have all the phones and the NBX plugged into 1 of the 3COM switches so the phones will still work.
Any help would be greatly appreciated!
Attached is the config of my Cisco 4507.
