Port Statistics In Device Manager, you can view statistics for data that passes through the
switch ports. If you use Parallel Redundancy Protocol (PRP), ports that belong
to a PRP channel configured on a RedBox are marked with an asterisk (*).
For more information about configuring PRP channels, see
page 214 .
From the Monitor menu, choose Port Statistics.
Table 115 - Port Statistics
Tab Description
Overview Displays the number of error packets that is received and sent from the port. This level of detail is not available from the Dashboard graphs.
The number of error packets can mean a duplex mismatch, incompatibilities with the port and its attached device, or faulty cables or attached
devices. Any of these problems can cause slow network performance, data loss, or lack of connectivity.
Transmit Detail Use this tab to troubleshoot unusual changes in network traffic. This tab displays these statistics:
• Unicast, multicast, and broadcast packets that are sent from each port
• Detailed statistics of errors that are sent to each port
If a port is sending an unusually high amount of traffic, such as multicast or broadcast packets, monitor the connected device to see whether
the traffic pattern is normal.
Receive Detail Use this tab to troubleshoot unusual changes in network traffic. This tab displays these statistics:
• Unicast, multicast, and broadcast packets that are received on each port
• Detailed statistics of errors that are received on each port
If a port is receiving an unusually high amount of traffic, such as multicast or broadcast packets, monitor the connected device to see whether
the traffic pattern is normal.
