Administrator Guide

Important Points to Remember
● The interface and port must be enabled (configured—see the interface command) before running TDR. An error
message is generated if you have not enabled the interface.
● The interface on the far-end device must be shut down before running TDR.
● Because TDR is an intrusive test on an interface that is not establishing a link, do not run TDR on an interface that is passing
traffic.
● When testing between two devices, do not run the test on both ends of the cable.
Virtual LAN (VLAN) Commands
The following commands configure and monitor virtual local area networks (VLANs). VLANs are a virtual interface and use many
of the same commands as physical interfaces.
You can configure an IP address only on the default VLAN. FTP, TFTP, ACLs, and SNMP are not supported on a VLAN.
Occasionally, while sending broadcast traffic over multiple VLANs, state of a VLAN interface may continually switch between
Master and Backup.
