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.

Tip: Rolling the mouse cursor over the port number displays the current port state.

A port number is displayed in one of three colors depending on the port’s current health:

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 cascade 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 line conditions, etc.

 

 

Gray

Unknown – The port status cannot be determined.

 

NoSFP – There is no SFP connector inserted in the port.

 

 

Port utilization is measured by a vertical bar that moves upwards as utilization increases. The vertical bar has the three distinct levels of utilization:

Bar Color

Indication

 

 

Green

The port is operating at optimal utilization.

 

 

Yellow

The port is experiencing 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.
