When to Use
To select screens to assign switched network ports to VLANs, define new
VLANs, and configure port filtering according to a VLAN list or
untagged frames. Network users can be logically grouped into VLANs
even if they span long physical distances over a vast, intricate physical
network. The VLAN Local Management menu items listed on the 802.1Q
VLAN Configuration Menu allow such VLANs to be configured on a
network at the switched port of the device or SmartSwitch chassis. Also,
some or all of the ports on the switch can be configured as GVRP ports,
which enable frames received with a particular VLAN ID and protocol to
be transmitted on a limited number of ports. This keeps the traffic
associated with a particular VLAN and protocol to be isolated from the
other parts of the network.
Before attempting the VLAN configuration, ensure that the device to be
configured has been set for 802.1Q SWITCHING mode. The mode
selection is a Local Management operation that is accessible through the
General Configuration screen of the device.
!
CAUTION
The device resets when changing operational modes.
