User-defined protocols

In addition to the standard protocols, user-defined protocol-based VLANs are supported. For user-defined protocol-based VLANs, the user specifies the Protocol Identifier (PID) for the VLAN. Any frames that match the specified PID in any of the following ways are assigned to that user-defined VLAN:

• The ethertype for Ethernet type 2 frames
• The PID in Ethernet SNAP frames
• The DSAP or SSAP value in Ethernet 802.2 frames

Certain predefined policy-based PIDs are reserved and are not available for user-defined PIDs. For a list of the reserved pre-defined policy-based PIDs, see Networking Concepts for the Passport 8000 Series Switch.
