Hardware Component Monitoring
Table 87 lists the individual Brocade FastIron switches and the hardware monitoring features they
support. These features are supported in the Layer 2, base Layer 3, edge Layer 3, and full Layer 3
software images.
NOTE
VCT is not supported on SX-FI48GPP, SX-FI-24GPP, SX-FI-24HF, SX-FI-2XG, and SX-FI-8XG.
The procedures in this chapter describe how to configure the software to monitor hardware
components.
Virtual cable testing
FastIron devices support Virtual Cable Test (VCT) technology. VCT technology enables the diagnosis
of a conductor (wire or cable) by sending a pulsed signal into the conductor, then examining the
reflection of that pulse. This method of cable analysis is referred to as Time Domain Reflectometry
(TDR). By examining the reflection, the Brocade device can detect and report cable statistics such
as local and remote link pair, cable length, and link status.
Virtual cable testing configuration notes
• This feature is supported on copper ports only. It is not supported on fiber ports.
• This feature is not supported on the SX-FI48GPP module running software release 07.2.02 or
later.
• This feature is not supported on SX-FI2XG, SX-FI8XG, SX-FI24HF, SX-FI24GPP, and SX-F!48GPP
modules running software release 07.3.00 or later.
• The port to which the cable is connected must be enabled when you issue the command to
diagnose the cable. If the port is disabled, the command is rejected.
• If the port is operating at 100 Mbps half-duplex, the TDR test on one pair will fail.
• If the remote pair is set to forced 100 Mbps, any change in MDI/MDIX may cause the device to
interpret the Multilevel Threshold-3 (MLT-3) as a reflected pulse, in which case, the device will
report a faulty condition. In this scenario, it is recommended that you run the TDR test a few
times for accurate results.
