Chapter 13 Configuring VLANs

Configuring VMPS

•IEEE 802.1x ports cannot be configured as dynamic-access ports. If you try to enable IEEE 802.1x on a dynamic-access (VQP) port, an error message appears, and IEEE 802.1x is not enabled. If you try to change an IEEE 802.1x-enabled port to dynamic VLAN assignment, an error message appears, and the VLAN configuration is not changed.

•Trunk ports cannot be dynamic-access ports, but you can enter the switchport access vlan dynamic interface configuration command for a trunk port. In this case, the switch retains the setting and applies it if the port is later configured as an access port.

You must turn off trunking on the port before the dynamic-access setting takes effect.

•Dynamic-access ports cannot be monitor ports.

•Secure ports cannot be dynamic-access ports. You must disable port security on a port before it becomes dynamic.

•Private VLAN ports cannot be dynamic-access ports.

•Dynamic-access ports cannot be members of an EtherChannel group.

•Port channels cannot be configured as dynamic-access ports.

•A dynamic-access port can participate in fallback bridging.

•The VTP management domain of the VMPS client and the VMPS server must be the same.

•The VLAN configured on the VMPS server should not be a voice VLAN.

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:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	vmps server ipaddress primary	Enter the IP address of the switch acting as the primary VMPS server.
Step 3
	vmps server ipaddress	(Optional) Enter the IP address of the switch acting as a secondary VMPS
		server.
		You can enter up to three secondary server addresses.
Step 4
	end	Return to privileged EXEC mode.
Step 5
	show vmps	Verify your entries in the VMPS Domain Server field of the display.
Step 6
	copy running-config startup-config	(Optional) Save your entries in the configuration file.
