• monitor interface
• show cong (from INTERFACE RANGE mode)
• show interfaces port-channel
NOTE: The Dell Networking OS implementation of LAG or Port Channel requires that you congure a LAG on both
switches manually. For information about Dell Networking OS link aggregation control protocol (LACP) for dynamic
LAGs, refer to the Link Aggregation Control Protocol (LACP) chapter. For more information about conguring and using
Port Channels, refer to the Dell PowerEdge M I/O Aggregator Conguration Guide
Time Domain Reectometer (TDR) Commands
TDR is useful for troubleshooting an interface that is not establishing a link; either it is apping or not coming up at all. TDR detects
open or short conditions of copper cables on 100/1000/10G Base-T modules.
• tdr-cable-test
• show tdr
Important Points to Remember
• The interface and port must be enabled (congured—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
trac.
• When testing between two devices, do not run the test on both ends of the cable.
Virtual LAN (VLAN) Commands
The following commands congure and monitor virtual local area networks (VLANs). VLANs are a virtual interface and use many of
the same commands as physical interfaces.
You can congure an IP address only on the default VLAN. FTP, TFTP, ACLs, and SNMP are not supported on a VLAN.
Occasionally, while sending broadcast trac over multiple VLANs, state of a VLAN interface may continually switch between Master
and Backup.
