Nortel Networks Optivity Switch Manager for LAN Switch Networks Release 1.0.0.0

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 module 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 module, the 16-bit PID assigned to a protocol-based VLAN only specifies 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
