User-Defined Protocol Identifier Description
In addition to the standard predefined protocols, user-defined protocol-based
VLANs are supported. For user-defined protocol-based VLANs, you specify 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
The following PIDs ( Table 25 ) are reserved and are not available for user-defined
PIDs.
