Direct Connections - Avaya 8800 Planning And Engineering, Network Design

• Port P3 must be a member of a routable VLAN but cannot be a member of the same VLAN as
Ports P1 and P2. VLAN tagging is not preserved on P3 ingress and egress packets.
For indirect user connections, you must disable routing on port P2. This allows the bridging of traffic
other than IP and routing of IP traffic outside of port number 2. In the latter case, port 1 has routing
enabled and allows routing of IP traffic to port 3. By disabling IP routing on port P2, no IP traffic
flows to this port.

Direct connections

To directly connect to the Avaya Ethernet Routing Switch 8800/8600, a user must create two
protocol-based VLANs on the port: one for PPPoE traffic and one for IP traffic (see the following
figure). When configured in this way:
• Port P1 is an access port.
Port P1 must belong to both the IP protocol-based VLAN and the PPPoE protocol-based
VLAN.
• Port P2 provides a connection to the ISP network.
P2 is configured for tagging to support PPPoE traffic to the ISP for multiple users. P2 ingress
and egress packets are tagged (the packet type is PPPoE).
• Port P3 provides a connection to the Content Delivery Network.
