User-Defined Protocol Identifier (PID) 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 (see
Table 3-15
) are reserved and are not available for
user-defined PIDs:
