Offline sequences Tx, Address ID errors

Page 110 highlights

Monitoring and Managing the Director ■ Address ID errors-A received frame had an unavailable or invalid Fibre Channel destination address, or an invalid Fibre Channel source address. This typically indicates the destination device is unavailable. ■ Frames too short-A received frame exceeded the Fibre Channel frame maximum size or was less than the Fibre Channel minimum size, indicating the frame arrived at the director's port corrupted. Frame corruption may be caused by device disconnection, an optical transceiver failure at the device, a bad fiber optic cable, or a poor cable connection. Operational Statistics The following describes the Operational Statistics that display for a selected port ■ Offline sequences Rx-The number of offline sequence that the port has received. ■ Offline sequences Tx-The number of offline sequence that the port has transmitted. ■ Link resets-The number of link reset protocol frames received/transmitted by this port from/to the attached device. The director transmits a link reset to initiate the link reset protocol or recover from a link timeout. This occurs normally to establish BB_Credit or on any port in order to recover lost BB_Credit. The director receives a link reset from an attached device if the device wishes to initiate the link reset or recover from a link timeout. Traffic Statistics with Receive and Transmit Values This section describes the types of Traffic Statistics that display for a selected port: ■ Link utilization %-There are separate values for transmit (Tx) and receive link utilization (Rx). The larger of these two values displays on the bar graph. The current link utilization for the port is expressed as a percentage. Each port can transmit or receive data at 100 Megabytes (MB) per second. This statistic shows the percentage of the maximum link utilization currently being used. Link utilization is calculated over one-second intervals. The maximum link utilization is 100%. ■ Frames Rx-The number of frames that the port has received. ■ Frames Tx-The number of frames that the port has transmitted. ■ Four byte words Rx-The number of words that the port has received. ■ Four byte words Tx-The number of words that the port has transmitted. 110 Director Product Manager User Guide

Monitoring and Managing the Director

Director Product Manager User Guide
Address ID errors—
A received frame had an unavailable or invalid Fibre
Channel destination address, or an invalid Fibre Channel source address. This
typically indicates the destination device is unavailable.
Frames too short—
A received frame exceeded the Fibre Channel frame
maximum size or was less than the Fibre Channel minimum size, indicating
the frame arrived at the director’s port corrupted. Frame corruption may be
caused by device disconnection, an optical transceiver failure at the device, a
bad fiber optic cable, or a poor cable connection.
Operational Statistics
The following describes the Operational Statistics that display for a selected port
Offline sequences Rx
—The number of offline sequence that the port has
received.
Offline sequences Tx
—The number of offline sequence that the port has
transmitted.
Link resets
—The number of link reset protocol frames received/transmitted
by this port from/to the attached device. The director transmits a link reset to
initiate the link reset protocol or recover from a link timeout. This occurs
normally to establish BB_Credit or on any port in order to recover lost
BB_Credit. The director receives a link reset from an attached device if the
device wishes to initiate the link reset or recover from a link timeout.
Traffic Statistics with Receive and Transmit Values
This section describes the types of Traffic Statistics that display for a selected
port:
Link utilization %
—There are separate values for transmit (Tx) and receive
link utilization (Rx). The larger of these two values displays on the bar graph.
The current link utilization for the port is expressed as a percentage. Each port
can transmit or receive data at 100 Megabytes (MB) per second. This statistic
shows the percentage of the maximum link utilization currently being used.
Link utilization is calculated over one-second intervals. The maximum link
utilization is 100%.
Frames Rx—
The number of frames that the port has received.
Frames Tx—
The number of frames that the port has transmitted.
Four byte words Rx—
The number of words that the port has received.
Four byte words Tx—
The number of words that the port has transmitted.
