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 4-224).
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).
protocol-vlan protocol-group (Configuring Groups)
This command creates a protocol group, or adds specific protocols to a group. Use
the no form to remove a protocol group.

• group-id - Group identifier of this protocol group. (Range: 1-2147483647)
• protocol-type - Protocol type. (Options: apple_talk, ip, ipx,
user-defined (0-ffff).
• frame-type - Frame type used by this protocol. (Options: ethernet, llc-other,
rfc-1042, snap_8021h). The frame-type can only be specified if the user
