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
copy running-config startup-config (Optional) Save your entries in the configuration file.
