Field Description
Information about the HDLC configuration.
• Policing bucket—Configured state of the receiving policer.
• Shaping bucket—Configured state of the transmitting shaper.
• Giant threshold—Giant threshold programmed into the hardware.
• Runt threshold—Runt threshold programmed into the hardware.
• Timeslots—Time slots configured on the interface.
• Buildout—(T1 only) Buildout setting: 0-132, 133-265, 266-398, 399-531, or
532-655 feet.
• Timeslots—Configured time slots for the interface.
• Byte encoding—(T1 only) Byte encoding used: Nx64K or Nx56K.
• Line encoding—Line encoding used. For T1, the value can be B8ZS or AMI. For
E1, the value is HDB3.
• Data inversion—HDLC data inversion setting: Enabled or Disabled.
• Idle cycle flag—Idle cycle flags.
• Start end flag—Start and end flag.
BERT (bit error rate test) checks the quality of the line. This output appears
only when a BERT is run on the interface.
• BERT time period—Configured total time period that the BERT is to run.
• Elapsed—Actual time elapsed since the start of the BERT (in seconds).
• Induced error rate—Configured rate at which the bit errors are induced in the
BERT pattern.
• Algorithm—Type of algorithm selected for the BERT.
Information about the configuration of the Packet Forwarding Engine:
• Destination slot—FPC slot number.
• PLP byte—Packet Level Protocol byte.
Information about the CoS queue for the physical interface.
• CoS transmit queue—Queue number and its associated user-configured
forwarding class name.
• Bandwidth %—Percentage of bandwidth allocated to the queue.
• Bandwidth bps—Bandwidth allocated to the queue (in bps).
• Buffer %—Percentage of buffer space allocated to the queue.
• Buffer usec—Amount of buffer space allocated to the queue, in microseconds.
This value is nonzero only if the buffer size is configured in terms of time.
• Priority—Queue priority: low or high.
• Limit—Displayed if rate limiting is configured for the queue. Possible values
are none and exact. If exact is configured, the queue transmits only up to the
configured bandwidth, even if excess bandwidth is available. If none is
configured, the queue transmits beyond the configured bandwidth if
bandwidth is available.
