Chapter 12 Configuring Dynamic VLAN Membership with VMPS Troubleshooting VMPS and Dynamic Port VLAN Membership Console> (enable) set port membership 3/1 static Port 3/1 vlan assignment set to static. Spantree port fast start option set to default for ports 3/1. Console> (enable) Troubleshooting VMPS and Dynamic Port VLAN Membership The next two sections describe how to troubleshoot VMPS and dynamic port VLAN membership. Troubleshooting VMPS Table 12-2 shows the VMPS error messages that you might see when you enter the set vmps state enable or the download vmps command. Table 12-2 VMPS Error Messages VMPS Error Message Recommended Action TFTP server IP address is not configured. Specify the TFTP server address using the set vmps tftpserver ip_addr [filename] command. Unable to contact the TFTP server 172.16.254.222. Enter a static route (using the set ip route command) to the TFTP server. File "vmps_configuration.db" not found on the TFTP Check the filename of the VMPS database configuration file on server 172.16.254.222. the TFTP server. Verify that the permissions are set correctly. Failed to download VMPS configuration file. Out of The VMPS database file might have more than 256 different memory. VLANs specified. Reduce the number of VLANs that are used in the file. Download aborted. File size larger that download The VMPS database file is longer than 21051 lines. If possible, buffer shorten the file. After VMPS successfully downloads the VMPS database configuration file, it parses the existing file on the VMPS server and builds a database. When the parsing is complete, VMPS displays statistics about the total number of lines parsed and the number of parsing errors. To obtain more information on VMPS parsing errors, set the syslog level for VMPS to 3 using the set logging level vmps command. Troubleshooting Dynamic Ports A dynamic port might shut down under these circumstances: • VMPS is in secure mode, and it is illegal for the host to connect to the port. The port shuts down to prevent the host from connecting to the network. • More than 50 active hosts reside on a dynamic port. To reenable a dynamic port that has been shut down, enter the set port enable command. 78-15486-01 Catalyst 4500 Series, Catalyst 2948G, Catalyst 2980G Switches Software Configuration Guide-Release 8.1 12-11
