AVAYA G450 Connections
- Thread starter wpetilli
- Start date
LAN ports connect to the LAN, WAN ports to the WAN 
Normally only one LAN port connects to your switching environment.
Depending on what your requirements are the ports are programmed on the G450 to fulfill a specific function, pretty muach as you would program a cisco router or similar for example.
If you want to use the G450 as a router you can hook the WAN link up to an ethernet WAN connection like a L2 fiber connection, or to a secondary router.
So, All pretty much depending on how the device is programmed.
Could you be more specific on your setup?

my environment is this g450 is a remote site system that is slaved/lsp off a hub site. we have an mpls router that connects to our core cisco switch. In that case I would assume all that is required is the Ethernet LAN ports be connected to our core cisco switch and wouldn't have a need for the WAN ports on the GW. I believe the BP may have connected the WAN port and I think it's wrong.

Well again, the way it is set up depends on design specifications,There are several ways to set up a network, and diffrent may not mean wrong.Your BP may have set up the WAN port as a routed port into a diffrent (virtual) LAN.
You need to know the design before you can conclude right or wrong
1: Ask your BP how they designed your network, a good BP has drawings on record of your network.
2: If you don't have access to the design, read them from the device.
Documentation can be found here:
You will see that the command structure is similar to Cisco's
So you need to match up the settings on both ends.
If the link is set up for trunk, it needs to be configured with trunk settings.
If it is setup as access-port you need to set it up with the correct settings on the Cisco switchport.
BE Carefull! changing something on the G450 end easily breaks the link to the media gateway, just saying that from experience.
Make sure you backup, and document all the settings before something is changed on the G450, but that should be best-practice anyway.
What also usually helps me is; set up a monitoring port on the cisco switch, and see what traffic passes a port using wireshark.
If no real traffic passes the port, it may just be plugged in incorrectly.

the GW came right up and registered to the hub site and about 4 hours later it then went offline. The bp thought it was a spanning tree issue since the gw had power and the link lights were lit and the network switch saw up/up, but with no data coming from the GW (no MAC even). The GW was not pingable as well. turning off spanning tree didn't work and now they deem this a faulty GW as it keeps rebooting, even with the mm pulled out.
