User-defined protocols in protocol-based VLANs

You can create protocol-based VLANs with a user-defined protocol for integration into existing networks where nonstandard protocols are used. When you select the usrDefined button, the VLAN, Insert Basic dialog box appears.

In the UserDefinedPID field, enter the PID of the protocol in the format: 0x (protocol type in hexadecimal value). The 16-bit PID assigned to a protocol-based VLAN specifies either an Ethertype, a DSAP/SSAP, or a SNAP PID, depending on whether the frame encapsulation is Ethernet 2, 802.2, or LLC-SNAP, respectively.

Refer to the section on user-defined protocols in Networking Concepts for the Accelar 1000 Series Switch Release 2.0 for more information about this topic and to see the actual values and how they are assigned.

The following PIDs are not valid:

• PID0x0000 through 0x05dc: overlap with the 802.3 frame length.
• PIDs of predefined protocols (for example, IP, IPX, AppleTalk).
• PID 0x8100: reserved by IEEE 802.1Q to identify tagged frames.
• PID0x9000: used by the diagnostic loopback frames.
• PID0x8808: used by IEEE 802.3x pause frames.
• PID0x4242: overlaps with the BPDU DSAP/SSAP.
