privacy, but the whole building has a shared high-speed connection to the ISP.
In order to accomplish this, P330 allows you to set multiple VLANs per port. The
three available Port Multi-VLAN binding modes are:
• Bind to All - the port is programmed to support the entire 3K VLANs range.
Traffic from any VLAN is forwarded through a port defined as “Bind to All”.
This is intended mainly for easy backbone link configuration
• Bind to Configured - the port supports all the VLANs configured in the
switch/stack. These may be either Port VLAN IDs (PVID) or VLANs that were
manually added to the switch.
• Statically Bound - the port supports VLANs manually configured on it.
L VLAN Binding — The forwarding mechanism of the P330-ML switches is
based on frame’s VLAN and MAC address. If a frame is destined to a known
MAC address but arrives on a different VLAN than the VLAN on which this
MAC address was learnt, this frame will be flooded as unknown to all ports that
are bound to its VLAN. Hence, VLAN binding should be executed with care,
especially on ports connected to workstations or servers.
Figure 11.3 illustrates these binding modes in P330.
