Check the Port Statistics
Use the Port Statistics window to display the statistics for data sent from and
received by the switch ports since the switch was last powered on, was restarted,
or since the statistics were last cleared.
The types of port statistics collected and displayed are grouped under these tabs
on the Port Statistics window:
• Overview Tab, page 4-19
• Transmit Detail Tab, page 4-20
• Receive Detail Tab, page 4-21
Speed The operating speed of the port. The speed can be 10, 100, or 1000 Mbps. This is
configured from Configure > Port Settings.
Duplex The duplex state of the port. The duplex mode can be full or half duplex. This is
configured from Configure > Port Settings.
Auto-MDIX The state of the automatic medium-dependent interface crossover (auto-MDIX) feature.
The feature can be enabled or disabled. This is configured from Configure > Port
Settings.
PoE The PoE state of the port:
• Off—A PoE device is not connected to the port.
• Admin Off—The port is set to never provide power to a connected PoE device.
• Error-Disabled—The port is disabled due to a misconfiguration or violation on the
switch.
• On—A PoE device is connected to the port, and this port can provide it with power.
• Power Deny—The power budget is allocated to other ports, and this port cannot
provide power to a connected PoE device.
If the port is supplying power to a device, the state includes the number of watts
that is allocated to the port.
