Understanding VMPS
This is an example of output for the show vmps privileged EXEC command, used to verify the VMPS
server IP address.

VQP Client Status:
--------------------
VMPS VQP Version: 1
Reconfirm Interval: 60 min
Server Retry Count: 3
VMPS domain server: 172.20.128.86 (primary, current)

VMPS Action: No Dynamic Port
Note The switch port that is connected to the VMPS server cannot be a dynamic access port. It can be
either a static access port or a trunk port. See the “Configuring an Ethernet Interface as a Trunk Port”
section on page 9-25.
Configuring Dynamic Access Ports on VMPS Clients
Caution Dynamic port VLAN membership is for end stations or hubs connected to end stations. Connecting
dynamic access ports to other switches can cause a loss of connectivity.
Beginning in privileged EXEC mode, follow these steps to configure a dynamic access port on a VMPS
client switch:
To return an interface to its default configuration, use the default interface interface-id interface
configuration command. To return an interface to its default switchport mode (dynamic desirable), use
the no switchport mode interface configuration command. To reset the access mode to the default
VLAN for the switch, use the no switchport access interface configuration command.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Enter interface configuration mode and the switch port that is
connected to the end station.
Step 3
switchport mode access Set the port to access mode.
Step 4
switchport access vlan dynamic Configure the port as eligible for dynamic VLAN membership.
The dynamic access port must be connected to an end station.
Step 5
end Return to privileged EXEC mode.
Step 6
show interfaces interface-id switchport Verify your entries in the Operational Mode field of the display.
Step 7
copy running-config startup-config (Optional) Save your entries in the configuration file.
