Chapter 11 W310 WLAN Gateway Layer 2 Features
In order to accomplish this, W310 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. 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.
VLAN Binding – The forwarding mechanism of the W310 is based on a 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 learned. This frame
will be flooded as unknown to all ports that are bound to its VLAN. So VLAN binding
should be executed with care, especially on ports connected to workstations or servers.
Figure 11.4 illustrates these binding modes in W310.

Bind to All
• Any VLAN in the range of
1-4094 will be allowed
access through this
port

Multiple VLAN Per-port Binding Modes
Static Binding
• The user manually specifies
the list of VLAN IDs to be
bound to the port, up to 253
VLANs
• Default mode for every port
• Only VLAN 9, and any other
VLANs statically configured
on the portwill be allowed to
access this port
Bind to Configured
• The VLAN table of the port will
support all the Static VLAN
entries and all the ports' VLAN
IDs (PVIDs) present in the
switch
• VLANs 1,3,5,9,10 coming from
the bus will be allowed access
through this port
