We have a Nortel 8310 that serves as our ethernet router. To this will be two catalyst 2900xls amoung other nortel switches.
We have voip phones, and computers attached to the phones internal switch. That duo is connected to a single port.
Thus we need vlans to sort the traffic.
The computers are set as vlan 5 for this building.
The phones are set as vlan 10 for this building.
Vlan 5 network 172.24.1.0/24
Vlan 10 network 172.24.4.0/24
The management vlan for all switches is 6.
Vlan 6 network 172.20.3.0/24
I have set up multivlan ports, 5 and 10 on all ports except:
fa 0/1 which will be a local troubleshooting port. It has vlan 6 only.
fa 0/24 which will be connected to the routing switch. It will have all 3 vlans.
The routing switch has all traffic coming from the 2900xl switch as default vlan of 5. So if a computer is plugged into the switch anywhere, it will be on the correct vlan. The phones are set to use vlan 10 on the phones themselves.
This is tested and working properly.
The issue comes into communicating with the management IP.
These are the commands issued:
int vlan 6
ip address 172.20.3.12 255.255.255.0
I know the issue is that the routing switch has an ip of 172.24.1.1/24 on the vlan 5, and all non tagged traffic counts as vlan 5, so when we try to connect to the 172.20.3.x network through that port, it doesn't work, as it is not on the 24.1.x network.
How can we resolve this to have the management ip forward its vlan tag as 6?
