Configuring user-defined protocols in protocol-based VLANs

You can create user-defined protocol-based VLANs in support of networks with non-standard protocols.

To create a user-defined protocol for a protocol-based VLAN:

1. From the Device Manager menu bar, choose VLAN > VLANs.

The VLAN dialog box opens to the Basic tab.

2. In the VLAN dialog box, click Insert.

The VLAN, Insert Basic dialog box opens.

3. In the Type field, click byProtocolId.
4. To specify the VLAN port membership, click the ellipsis (...) for one of the following fields.
• Port Members
• StaticMembers
• NotAllowedToJoin

The VlanPortMembers dialog box opens.

5. In the VlanPortMembers dialog box, click each port button to achieve the desired membership color.
• Yellow: Potential members--dynamic. Potential members are treated as always members.
• Green: Always members--static
• Red: Never members--not allowed to join
  
  

  Note: In a user-defined protocol-based VLAN on an 8600 module, a potential member becomes an active member when a frame from the specified protocol is received. On an 8100 module, all potential members are active members.

  
  
6. In the Protocolid field, click usrDefined.

The UserDefinedPID field becomes editable.

7. In the UserDefinedPID field, enter the PID for the protocol in the format: 0x (protocol type in hexadecimal).

In the 8600 modules, 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.

In the 8100 modules, 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
8. Do one of the following:
• For 8100 modules, go to Step 9.
• For 8600 modules, in the AgingTime field, specify the timeout period, in seconds, for aging out the dynamic member ports of the VLAN, or use the default of 600 seconds.
9. In the QosLevel field, click a level (0-7).
10. Click Insert.

The VLAN, Insert Basic dialog box closes, and the protocol-based VLAN is added to the Basic tab of the VLAN dialog box.

11. Click Apply > Close.

The non-standard protocol-based VLAN is configured.
