Example
The following example shows how to display information for VLAN 1.
Configuring Protocol-based VLANs
The network devices required to support multiple protocols cannot be
easily grouped into a common VLAN. This may require non-standard
devices to pass traffic between different VLANs in order to encompass all
the devices participating in a specific protocol. This kind of configuration
deprives users of the basic benefits of VLANs, including security and easy
accessibility.
To avoid these problems, you can configure this switch with
protocol-based VLANs that divide the physical network into logical
VLAN groups for each required protocol. When a frame is received at a
port, its VLAN membership can then be determined based on the
protocol type in use by the inbound packets.
