Port Utilization and Health
Port utilization measures the amount of traffic passing into a port over a period of time. For example, if
an initiator is transmitting data to a target, the initiator port displays a port utilization value (%) while the
target port does not. If the same initiator is receiving data from the target, the target port displays a port
utilization value (%) while the initiator port displays does not.
This part of the web page displays each port number, the port’s current health status, and a vertical bar
indicating the port utilization.
A port number is displayed in one of three colors depending on the port’s current health:
Port utilization is measured by a vertical bar that moves upwards as utilization increases. The vertical
bar has the three distinct levels of utilization:
Tip: Rolling the mouse cursor over the port number displays the current port state.
Port Color Indication
Green An SFP is inserted into the port and a device is connected to the SFP.
Yellow Bypassed – The port is bypassed . An SFP may be inserted in the port but there
may not be a device connected to the SFP.
Loopback – There is no device connected to the port. The transmit and receiver
are connected together on the SFP transceiver.
LIPF8Present – If the switch is receiving an F8 Failure notification, the port is
bypassed to allow remaining devices to proceed with initialization.
Redundant – The port is a failover link in a casc ade and is not currently active.
Red TxFault – Detects an SFP transmitter fault.
DiagTx – Detects Ordered Sets being transmitted, so traffic cannot be passed
through the port.
DataTimeout – Detects a data timeout fault.
RxLoss – Detects a loss of received signal amplitude from the device.
SyncLoss – Detects a loss of word synchronization for a specified time, which may
be caused by poor signal strength, intermittent li ne conditions, etc.
Gray Unknown – The port status cannot be determined.
NoSFP – There is no SFP connector inserted in the port.
Bar Color Indication
Green The port is operating at optimal utilization.
Yellow The port is experienci ng periods of heavy traffic.
Red The port has too much traffic on it and is not operating at desired levels. Some
devices should be transferred to other ports to improve port utilization.
