3. Configuration Overview
3.1. Port Configuration Overview
In the main office, ports 3:1 to 3:4 on the Extreme Networks Aspen are used to connect to the
Avaya S8500 Media Server and the Avaya G650 Media Gateway (IPSI, C-LAN and MEDPRO).
It is recommended to configure the Avaya S8500 Media Server and the Avaya G650 Media
Gateway IPSI on one VLAN and the Avaya G650 Media Gateway C-LAN and MEDPRO on
another VLAN. In each of the offices, a set of ports is used to connect end-user devices. For
example, the ports used for end-user devices may connect to a computer, an IP telephone, or an
IP telephone with an attached computer. This is accomplished by configuring two VLANs on the
end-user ports. The tagged VLAN is used for IP telephones, and the untagged VLAN is for
computers, whether standalone, or attached to an IP telephone.
