Field descriptions
list measurements clan ethernet
Use list measurements clan ethernet to list a 24-hour history of packet-level
statistics. Use the history to review LAN performance characteristics. For
example:
■
High collision counts could indicate high traffic on the LAN segment
(congestion on the bus).
■
High Cyclic Redundancy Check (CRC—detects and corrects errors on
every frame) errors could show
— the LAN connection may be “noisy”
— a wire connection is loose
— a wire is frayed or broken.
The 24-hour history gives the ability to look back at these measures if the trouble
cleared.
The data is collected at 15-minute intervals over 24 hours for the Cyclic
Redundancy Check (CRC) and collisions for ethernet connections. If the data
cannot be retrieved for the 15-minute interval,
N/A
displays in the field. The delta
(the change from the last inquiry) and the total are provided for each error count.
After the occurrence of “N/A” (not available), the delta equals the total.
The primary use of this command is to quickly and unambiguously determine if
the fault lies within the Avaya-provided equipment or if the fault is with the LAN or
LAN administration to which the Avaya equipment is connected.
Port
The port address (cabinet-carrier-slot-circuit) of the marked port.
Board-Type
The type of circuit pack containing the marked port. If this circuit pack
information is no longer available because the circuit pack was removed
after the port was marked, the
Board-Type
field is blank.
