Configuring the Switch
Command Usage
To configure protocol-based VLANs, follow these steps:
1. First configure VLAN groups for the protocols you want to use (3-170). 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 Configuration page.
3. Then map the protocol for each interface to the appropriate VLAN using the
Protocol VLAN Port Configuration page.
Configuring Protocol VLAN Groups
Use the Protocol VLAN Configuration menu to create or remove protocol groups.
Command Attributes
• Protocol Group ID – Protocol Group ID assigned to the Protocol VLAN Group.
(Range: 1-2147483647)
• Frame Type – Choose either Ethernet, RFC 1042, or LLC Other as the frame type
used by this protocol.
• Protocol Type – Specifies the protocol type to match. The available options are
IP, ARP, RARP, and user-defined (0801-FFFF hexadecimal). If LLC Other is
chosen for the Frame Type, the only available Protocol Type is IPX Raw.
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
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.
Web – Click VLAN, Protocol VLAN, Configuration. Enter a protocol group ID, frame
type and protocol type, then click Apply.
