Chapter 12 Configuring VLANs
Configuring VMPS
• 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.
• 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.
• VQP does not support extended-range VLANs (VLAN IDs higher than 1006). Extended-range
VLANs cannot be configured by VMPS.
• 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 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 12-19.
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 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
