Configuring VMPS
Configuring the VMPS Client
You configure dynamic VLANs by using the VMPS (server). The switch can be a VMPS client; it cannot
be a VMPS server.

Entering the IP Address of the VMPS

You must first enter the IP address of the server to configure the switch as a client.
Note If the VMPS is being defined for a cluster of switches, enter the address on the command switch.
Beginning in privileged EXEC mode, follow these steps to enter the IP address of the VMPS:
Note The switch port that is connected to the VMPS server cannot be a dynamic a cce ss po rt. It ca n b e eit her
a static access port or a trunk port. See the Configuring an Ethernet Interface as a Trunk Port section
on page 17-17.

Configuring Dynamic Access Ports on VMPS Clients

If you are configuring a port on a cluster member switch as a dynamic port, first use the rcommand
privileged EXEC command to log into the member switch.
Caution Dynamic port VLAN membership is for end stations or h ubs co nnec ted to en d sta tio ns. Co nne ctin g
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:
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 vmps server ipaddress primary Enter the IP address of the switch acting as the primary VMPS server.
Step3 vmps server ipaddress Enter the IP address of the switch acting as a secondary V MP S s erver.
You can enter up to three secondary server addresses.
Step4 end Return to privileged EXEC mode.
Step5 show vmps Verify your entries in the VMPS Domain Server field of the display.
Step6 copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 interface interface-id Enter interface configuration mode and the switch port that is
connected to the end station.
Step3 switchport mode access Set the port to access mode.
