LINKCONTROL Command
NS 3000/iX LAPBMUX Link Statistics
field can be set to a value of 8 or 128, meaning that frames are
numbered from either 0 through 7, or 0 through 127.
Buffer Size — The Buffer Size field displays the current buffer size.
This value will be equal to the buffer size configured in the NMMGR
Link screen plus 4 bytes of overhead that is added by the level 3
protocol.
STATISTICS Parameter Fields
The STATISTICS parameter for LAPBMUX links displays many fields
in addition to the
LINKSTATE parameter fields. The CONFIGURATION
parameter fields are not displayed when this parameter is used. For an
example of the data that is displayed when you issue the LINKCONTROL
linkname ;STATUS=STATISTICS command:
Transmit bytes 11543567876 Receive bytes 32948732576
TransmitS 13166130 ReceiveS 18338778
Transmits ctrl bytes 0 Receive ctrl bytes 0
Transmit ctrl 0 Receive ctrl 0
Transmit overruns 0 Receive overruns 0
Tx deferred: iova 0 Recv deferred: iova 0
Tx deferred: buffer 0 Recv dropped: buffer 0
Level-2 connects 1 Recv dropped: addr 0
Level-2 disconnects 0 Recv dropped: other 0
Connect timeouts 0 Secs since clear 173980
This command displays statistics about data transmitted and received
across the link. Many field values are summations. Over time, the
values in these fields reach their maximum possible value. When this
occurs, these fields can only be reset manually.
Transmit bytes — Total number of bytes successfully transmitted
onto the medium. This includes normal data bytes as well as control
data bytes. The maximum printable value of this 64-bit field is 17
digits, or about 99 million Gbytes. In the previous example, 10.1 million
bytes were transmitted, or about 9.7 Mbytes.
Transmits — Total number of frames successfully transmitted onto
the medium at normal priority. Normal data as well as the control data
frames. The byte count given by Transmit bytes is distributed over this
number of frames. The maximum printable value of this 64-bit field is
17 digits, or about 99 million billion frames. In the previous example
above, 127700 frames were transmitted at normal priority.
Transmit ctrl bytes — Total number of control bytes successfully
transmitted onto the medium. The maximum printable value of this
64-bit field is 17 digits, or about 99 million Gbytes. In the previous
example, 0 control data bytes were transmitted.
Transmit ctrl — Total number of control frames successfully
transmitted onto the medium at normal priority. The byte count given
