Configuring VMPS
Troubleshooting Dynamic-Access Port VLAN Membership
The VMPS shuts down a dynamic-access port under these conditions:
The VMPS is in secure mode, and it does not allow the host to connect to the port. The VMPS shuts
down the port to prevent the host from connecting to the network.
More than 20 active hosts reside on a dynamic-access port.
To re-enable a disabled dynamic-access port, enter the shutdown interface configuration command
followed by the no shutdown interface configuration command.
VMPS Configuration Example
Figure 12-4 shows a network with a VMPS server switch and VMPS client switches with
dynamic-access ports. In this example, these assumptions apply:
The VMPS server and the VMPS client are separate switches.
The Catalyst 6500 series Switch A is the primary VMPS server.
The Catalyst 6500 series Switch C and Switch J are secondary VMPS servers.
End stations are connected to the clients, Switch B and Switch I.
The database configuration file is stored on the TFTP server with the IP address 172.20.22.7.
