User-defined protocols in a protocol-based VLAN

You can create a protocol-based VLAN with a user-defined protocol for integration into existing networks where nonstandard protocols are used.

In the UserDefinedPId text box, enter the PID of the protocol in the format 0x (protocol type in decimal value).

• For a Passport 8600 switch and Passport 1000 Series switch, 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.
• For a Passport 8100 switch, the 16-bit PID assigned to a protocol-based VLAN specifies only an Ethertype for Ethernet 2 frame encapsulation.

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 802.1Q to identify tagged frames
• PID0x9000: used by the diagnostic loopback frames
• PID0x8808: used by 802.3x pause frames
• PID0x4242: overlaps with the BPDU DSAP/SSAP
