Configuring Ports
Switch Port Features
The Avaya P580 and P882 Multiservice switches support up to 1000
VLANs and also support multiple forwarding databases. This means that
each VLAN is associated with its own Address Forwarding Table (AFT).
Therefore, identical MAC addresses can simultaneously exist on multiple
VLANs. The Avaya Multiservice switches provide parameters for
configuring VLAN/port associations.
This section provides the following:

Relationship Between Different Switch Port Parameters
■
Assigning VLANs to a Port and Associated Issues
■
Setting the Port VLAN attribute in the Switch Port Configuration
Web page. This identifies the VLAN to which all untagged frames
received on the port are classified. Note that a port has exactly one
Port VLAN. Changing this to a new VLAN removes the port from
the old VLAN.
■
Setting the VLAN Binding attribute in the Switch Port
Configuration Web page to Bind to All. This causes the port to be
bound to all VLANs known to the switch (now and in the future).
This is not recommended when the switches on both ends of the link
function as a router. This setting should be used on links that
connect two Layer 2 switches.
■
Setting the VLAN Binding attribute in the Switch Port
Configuration Web page to Bind to Received. This causes the port
to be bound to all VLANs identified by the VLAN tag in IEEE
802.1Q and Multi-Layer tagged frames received on this port.
Consequently, ports are bound to those VLANs that actually have
members that are reachable through the port.
■ Manually creating a VLAN Switch Port via the Web Agent or CLI.
Relationship Between Different Switch Port Parameters
Table 8-2 shows the relationship between Port VLAN / Trunk Mode /
VLAN Binding parameters when using the VLAN Operational Rules.
