Chapter 2 Cisco IOS Commands for the Catalyst 4500 Series Switches
vmps server
vmps server
To configure the primary VLAN Membership Policy Server (VMPS) and up to three secondary servers,
use the vmps server command. To remove a VMPS server, use the no form of this command.
vmps server ipaddress [primary]
no vmps server ipaddress
Syntax Description
Defaults No primary or secondary VMPS servers are defined.
Command Modes Global configuration mode
Command History
Usage Guidelines The first server that you entered is automatically selected as the primary server whether or not primary
is entered. You can override the first server address by using primary in a subsequent command.
If a member switch in a cluster configuration does not have an IP address, the cluster does not use the
VMPS server that is configured for that member switch. Instead, the cluster uses the VMPS server on
the command switch, and the command switch proxies the VMPS requests. The VMPS server treats the
cluster as a single switch and uses the IP address of the command switch to respond to requests.
When using the no form without specifying the ipaddress, all configured servers are deleted. If you
delete all servers when dynamic-access ports are present, the switch cannot forward the packets from the
new sources on these ports because it cannot query the VMPS.
You can verify your setting by entering the show vmps command and examining information in the
VMPS Domain Server row.
Examples This example shows how to configure the server with IP address 191.10.49.20 as the primary VMPS
server. The servers with IP addresses 191.10.49.21 and 191.10.49.22 are configured as secondary
servers:
Switch(config)# vmps server 191.10.49.20 primary
Switch(config)# vmps server 191.10.49.21
Switch(config)# vmps server 191.10.49.22
Switch(config)#
ipaddress IP address or host name of the primary or secondary VMPS servers. If you specify
a hostname, the Domain Name System (DNS) server must be configured.
primary (Optional) Determines whether primary or secondary VMPS servers are being
configured.
Release Modification
12.1(4)EA1 Support for this command was introduced on the Catalyst 4500 series switch.
