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.
To configure protocol-based VLANs, follow these steps:
1.
First configure VLAN groups for the protocols you want to use (page 4-221).
Although not mandatory, we suggest configuring a separate VLAN for each
major protocol running on your network. Do not add port members at this time.
2.
Create a protocol group for each of the protocols you want to assign to a VLAN
using the
protocol-vlan protocol-group
command (General Configuration
mode).
3.
Then map the protocol for each interface to the appropriate VLAN using the
protocol-vlan protocol-group
command (Interface Configuration mode).
Note:
Traffic which matches IP Protocol Ethernet Frames is mapped to the VLAN
(VLAN 1) that has been configured with the switch’s administrative IP. IP Protocol
