About user-defined protocol-based VLANs
You can create user-defined protocol-based VLANs in support of networks with non-standard protocols. For user-defined protocol-based VLANs, you can specify the Protocol Identifier (PID) for the VLAN. Frames that match the specified PID for the following 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 table lists reserved, predefined policy-based PIDs which cannot be used as user-defined PIDs.
