Mitel 3300 MXe III L2 Switch Port Problems

[rhenarie]

Ok,

I have a 3300 MXe III in which I am unable to communicate with from my "data" network (default VLAN 1 phone system on different subnet on VLAN 2).  The system is working fine with the exception of being able to administer from a different sub-net.  Here is the config of the switchport my 3300 is connected to:

interface GigabitEthernet1/0/45
switchport access vlan 2
switchport mode access
switchport voice vlan 2
priority-queue out
mls qos trust dscp
spanning-tree portfast
spanning-tree bpduguard enable

I am able to connect a laptop to the second port on the 3300 and administer it, but not from across VLANs.

What am I missing here?

A layer 3 device that routes between them

Or a default gateway on the MXe

untag the port on the switch.

I do have a Router in the mix. 

Looking into the tagging of the port aspect now. 
As for this, yes, if we untag the port, then yes, we are able to get to it in that manner, but we lose connectivity to the phones and phones do not obtain DHCP info.

The odd thing is, from vlan1, I am able to ping all the phones on which get their DHCP address from the 3300 on vlan2 and the "pass-through/switch port" on the phones allow data so the routing seems fine.

I just cannot ping nor reach the 3300 from the data vlan.

Set a route in the router for letting the two vlans communicate (possible there may be a facility in this already ).

We usually just set a switch port untagged for programming the 3300 and made it that purpose only or IIRC it can be set as a trunk port on the port between the switch and the router (it then uses the router to route as above). Different switches/routers call it different things just to confuse matters....

On your controller, what is the "Gateway IP Address"? (System IP Properties form).
 
Which device has this IP address configured on your network?
