I have be onsite today assisting with the network configuration of a new 3300.
I have configured the switches with two Vlans:
Vlan 1 (default) data network
Vlan 2 VIOP Network
All the ports are in both Vlans, untagged in Vlan 1 and tagged in vlan 2
The data network is on IP range 10.0.0.x and the phone system is on 10.0.1.x, both on class c subnet 255.255.255.0
We are running two DHCP servers, one in vlan1 serving data and the 3300 which is serving vlan 2.
The phone engineer fired up the 3300 and a few handsets and they worked as expected, picked up IP address from 3300 in the 10.0.1.x range. We then plugged a laptop into the phone and these picked up an IP from VLan 1 on the 10.0.0.x range, as expected.
We have supplied a server and this is set on the same IP range as the 3300:
the 3300 is IP 10.0.1.2
the server is IP 10.0.1.1
The problems we have the server does not communicate with the 3300.
We don't receive a ping response and we can't get into the management screen, but if we change the port the 3300 is plugged into to untagged in vlan 2 (this process removes it from vlan1), we can ping and access it from the server, however then the phones stop working, I believe this is down to the fact the phones will only respond to tagged packets?
One other point to mention is the port the server is plugged into is untagged on vlan2 and not in vlan1. When I changed it to tagged on vlan 2 it didn’t work.
The reason I changed it to untagged on vlan 2 is it would not see the gateway which is on 10.0.1.254,
this port it also untagged on vlan 2 only.
There are two ports on the front of the 3300, if we plug a laptop directly into this we can access the 3300, if we then put that same laptop into the HP switch with a manual IP on VLan2, no response.
We need the phone system to be able to serve the phones on vlan 2 and also be able to access the system on the server is vlan 2.
Is there something simple that we are missing here?
Any help would be greatly appreciated.
