To configure protocol-based VLANs, follow these steps:
1. First configure VLAN groups for the protocols you want to use (page 4-242).
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 add command.
3. Then map the protocol group to the appropriate VLAN using the protocol-vlan
protocol-group vlan command.
Note:
Traffic which matches IP Protocol Ethernet Frames is mapped to the VLAN (VLAN 1 by
default) that has been configured with the switch’s administrative IP. IP Protocol
Ethernet traffic must not be mapped to another VLAN or you will lose administrative
network connectivity to the switch. If lost in this manner, network access can be
regained by removing the offending Protocol VLAN rule via the console. Alternately, the
switch can be power-cycled, however all unsaved configuration changes will be lost.
protocol-vlan protocol-group (Configuring Groups)
This command creates a protocol group, or adds specific protocols to a group. Only one
frame type and protocol type can be added to a protocol group. Use the no form to
remove a protocol group.
Syntax
protocol-vlan protocol-group group-id [{add | remove} frame-type frame
protocol-type protocol]
no protocol-vlan protocol-group group-id
• group-id - Group identifier of this protocol group. (Range: 1-2147483647)
• frame
28
- Frame type used by this protocol. (Options: ethernet, rfc_1042,
llc_other)
• protocol - Protocol type. The only option for the llc_other frame type is ipx_raw.
The options for all other frames types include: ip, arp, and rarp.
Default Setting
No protocol groups are configured.
Command Mode
Global Configuration
Example
The following creates protocol group 2, and specifies Ethernet frames transmitting ARP
protocol type traffic:
28. SNAP frame types are not supported by this switch due to hardware limitations.
Console(config)#protocol-vlan protocol-group 2 add frame-type ethernet
protocol-type arp
Console(config)#
