140 Edge Switch 2/24 Service Manual

— Discarded frames.

■ Error statistics—The Performance View displays the following error

statistics for the port:

— Link failures—Link failures are recorded in response to an NOS,

protocol time-out, or port failure. At the Hardware View, a yellow

triangle appears to indicate a link incident, or a blinking red and yellow

diamond displays to indicate a port failure.

— Sync losses—Synchronization losses are detected because an attached

device was reset or disconnected from the port. At the Hardware View, a

yellow triangle displays to indicate a link incident.

— Signal losses—Signal losses are detected because an attached device was

reset or disconnected from the port. At the Hardware View, a yellow

triangle displays to indicate a link incident.

— Primitive sequence errors—Incorrect primitive sequences are received

from an attached device, indicating Fibre Channel link-level protocol

violations. At the Hardware View, a yellow triangle displays to indicate

a link incident.

— Discarded frames—Received frames could not be routed and were

discarded because the frame timed out (insufficient buffer-to-buffer

credit) or the destination device was not logged into the switch.

— Invalid transmission words—Several transmission words were received

with encoding errors, indicating an attached device is not operating in

conformance with the Fibre Channel specification.

— CRC errors—Received frames failed CRC validation, indicating the

frames arrived at the switch 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.

— Delimiter errors—Received frames had frame delimiter errors,

indicating the frame arrived at the switch 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.

— Address ID errors—Received frames had unavailable or invalid Fibre

Channel destination addresses, or invalid Fibre Channel source addresses.

This typically indicates the destination device is unavailable.
