Frame Relay Statistics

Physical Interface
Transmit
The percentage of line capacity currently used for transmitting.

Receive
The percentage of line capacity currently used for receiving.

Ave. frames/s
The average per-second rate of transmitted and received frames on this line.

Frames/s
The current per-second rate of transmitted and received frames on this line.

Ave. bytes/s
The average per-second rate of transmitted and received bytes on this line.

Bytes/s
The current per-second rate of transmitted and received bytes on this line.

Clock timeout
The number of times the adapter firmware is unable to detect a clock signal. This increments only when external clocking is configured.

Overrun
The number of erroneously long frames received. These are frames that are too large for the adapter to buffer. This can be caused by any of the following:

External clocking is configured and the device providing the clock is not working.
Internal clocking is configured and the adapter is not working properly.
The cable or line is defective.
The DataFire Electrical Interface is not configured correctly.

CRC
The number of frames received with cyclic redundancy check (CRC) errors. This indicates problems with the line itself or with the Clocking or Electrical Interface configuration.

Bit error
The number of frames received with bit errors.

Over flow
The number of received frames that exceeded the configured maximum frame size.

Abort
The number of abort frames received.

Frame Relay
Invalid frames received
The number of invalid frames received on this line. An invalid frame is one that does not conform to frame relay specifications.

Too short
The number of frames received that were under five bytes. This indicates either that the peer is sending short frames or that frames are being truncated in transit.

Too long
The number of frames received that were longer than the configured maximum. This indicates that the peer is sending long frames.

Invalid DLCI
The number of frames received with DLCIs outside the valid range. (16 to 991). If you receive these consistently, see your network service provider.

Unknown DLCI
The number of frames received with DLCIs that do not appear in the adapter configuration. If you receive these consistently, see your network service provider to ensure that you are using the correct DLCIs.

FECN
The number of forward explicit congestion notification (FECN) messages received. Use this statistic as an indication of network congestion.

BECN
The number of backward explicit congestion notification (BECN) messages received on this line. Use this statistic as an indication of network congestion.

Status message
The number of LMI status messages transmitted and received. Typically, the adapter receives status messages from the network switch. It will transmit them only if it is configured to perform the LMI switch function.

Status enquiry
The number of LMI status enquiry transmitted and received. Typically, the adapter transmits status inquiry messages. The adapter will receive them only if it is configured to perform the LMI switch function.

Update status
The number of update (full) status messages transmitted and received. Typically, the adapter receives Update status message. The adapter transmits them only if it is configured to perform the LMI switch function.

LMI Errors
The number of LMI protocol errors on this line.

Sync 2000/570 Cards Only
Line Speed
Is the actual data rate of the line in bits-per-second.

Line Status
Is one of the following conditions: Active, pending, or inactive.

Configured Baud Rate
Is the baud rate for the line in bits-per-second.

Max Frame Size
Is the maximum frame size used on this line.

Line Options
Is the line encoding scheme used on this line, either NRZ or NRZ1.

Duplex
Is either full- or half-duplex.

Cable Type
Is the cable type used to connected the adapter to the CSU/DSU.

Active Signals
Are the signals asserted, such as DTR, DSR, etc.

Permanent Virtual Circuit
Normal frames
The number of frames transmitted on this virtual circuit within the CIR.

Excess frames
The number of frames transmitted on this virtual circuit in excess of the CIR.

Hold frames
The number of frames on this virtual circuit that had to be buffered before transmission to avoid exceeding the CIR.

Dropped frames
The number of transmit frames on this virtual circuit that had to be dropped to avoid exceeding the CIR.

Unknown protocol
The number of frames received carrying network-layer protocols that the adapter did not recognize or was not configured for.

Unknown frame
The number of frames received on this virtual circuit that the adapter could not identify.

Lost frame
The number of received frames that the adapter had to discard because fragments were lost in transit.

Unknown origination code
The number of frames received with an invalid Organization Unique Identifier (OUI).
