This window is available for Catalyst 2900 XL, 2950, 3500 XL, and 3550 switches. It appears when you choose VLAN > VMPS on the menu bar. You can also click here to launch it. Use it to:
The settings that you make in this window are propagated to all the members of the cluster.
Fields in the VMPS Info tab have these meanings:
Field | Description |
VLAN Query Protocol Version | The VQP client sends only VQP version 1 requests to the VMPS for VLAN assignment. This field is read-only. |
Current VMPS | The address of the VMPS server currently responding to VQP client requests. If no secondary servers are configured, the current VMPS server address and the primary VMPS server address are the same. By default, no primary or secondary servers are configured. If the current server is not the primary server, the switch tries to contact the primary server every 5 minutes. If contact is reestablished, the primary server becomes the current server again. This field is read-only. |
Primary VMPS | The address of the primary VMPS server that responds to VQP client requests. By default, no primary servers are configured. This field is read-only. |
Number of Retries | Number of times a client repeats requests if the VMPS does not respond. The default number of retries is 3, but you can change it. (See Setting VMPS Client Parameter.) |
Reconfirmation Interval | Queries are periodically sent to reconfirm VLAN membership
of addresses already learned on the port. By default, these messages are
sent every 60 minutes, but you can change the interval. (See Setting
VMPS Client Parameters.) These status messages are valid: - reconfirm in progress - reconfirm completed successfully - reconfirm failed because no VMPS responded - no VMPS configured - no dynamic port configured - no hosts on dynamic port - no reconfirmation has been done |
By default, the client queries the VMPS every 60 minutes to reconfirm all VLAN assignments. You can change the reconfirmation interval or reconfirm the assignments on demand.
To reconfirm dynamic VLAN membership, click Refresh in the Reconfirmation Membership section.
Before configuring the switch (VMPS client) for dynamic VLAN membership, you must first set up the VMPS server. For information on setting up and troubleshooting the server, see the Catalyst 5000 Series Software Configuration Guide or the appropriate documentation.
To configure the client for dynamic VLAN membership:
To remove a server from the list of designated VMPS servers:
Note: If you delete all servers when dynamic-access ports are present, the switch cannot forward packets from new sources on these ports because it cannot query the VMPS.
