Chapter 16 Configuring VLANs, VTP, and VMPS
VLAN Membership Policy Server
A maximum of 50 hosts are supported on a given port at any given time. Once this maximum is exceeded,
the port is shut down, irrespective of the operating mode of the VMPS server.
Note The VMPS shuts down a dynamic port if more than 50 hosts are active on that port.
Default VMPS Client Configuration
Table 16-4 shows the default VMPS and dynamic port configuration on client switches.
Configuring a Switch as a VMPS Client
This section contains the following topics:
• Configuring the IP Address of the VMPS Server, page 16-24
• Configuring Dynamic Access Ports on a VMPS Client, page 16-25
• Reconfirming VLAN Memberships, page 16-26

of the switch acting as the VMPS.
To define the primary and secondary VMPS on a Catalyst 4500 series switch, perform this task:
This example shows how to define the primary and secondary VMPS devices:
Switch# configure terminal
