Chapter 15 Configuring VLANs

Configuring VMPS

• 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:

Note You must have IP connectivity to the VMPS for dynamic-access ports to work. You can test for IP

connectivity by pinging the IP address of the VMPS and verifying that you get a response.

Configuring Dynamic-Access Ports on VMPS Clients

If you are configuring a port on a cluster member switch as a dynamic-access port, first use the

rcommand privileged EXEC command to log in to the cluster member switch.

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
