Forwarding
Rules These rules determine the set of ports on the switch through which
members of the VLAN can be reached. This is called binding a port
to a VLAN. A port may be bound to a VLAN using the following four
methods:
■
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).
■
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 CLI.
Egress Rules For a given port/VLAN combination, these rules determine whether
frames transmitted from the port on the VLAN are tagged or
untagged. This is accomplished by setting the Trunk Mode attribute
in the Switch Port Configuration Web page. For example, choosing
the IEEE 802.1Q Trunk Mode causes all frames transmitted out of
the port to be tagged using the IEEE 802.1Q tag header format.
Individual port/VLAN combinations may be changed to cause
frames transmitted from the port to be untagged for particular
VLANs.
