OPTIONS
       Options (flags) that can be passed anywhere in the command chain.

       -h, --help
              Show help about last valid command. For example tipc link --help
              will show link help and tipc --help will show general help. The
              position of the option in the string is irrelevant.

DESCRIPTION
   Link statistics
       ACTIVE link state
              An ACTIVE link is serving traffic. Two links to the same node
              can become ACTIVE if they have the same link priority.  If there
              is more than two links with the same priority the additional
              links will be put in STANDBY state.

       STANDBY link state
              A STANDBY link has lower link priority than an ACTIVE link. A
              STANDBY link has control traffic flowing and is ready to take
              over should the ACTIVE link(s) go down.

       MTU
              The Maximum Transmission Unit. The two endpoints advertise their
              default or configured MTU at initial link setup and will agree
              to use the lower of the two values should they differ.

       Packets
              The total amount of transmitted or received TIPC packets on a
              link. Including fragmented and bundled packets.

       Fragments
              Represented in the form fragments/fragmented.  Where fragmented
              is the amount of data messages which have been broken into frag-
              ments.  Subsequently the fragments are the total amount of pack-
              ets that the fragmented messages has been broken into.

       Bundles
              Represented in the form bundles/bundled.  If a link becomes con-
              gested the link will attempt to bundle data from small bundled
              packets into bundles of full MTU size packets before they are
              transmitted.

       Profile
              Shows the average packet size in octets/bytes for a sample of
              packets. It also shows the packet size distribution of the sam-
              states - Number of link state messages

              probes - Link state messages with probe flag set. Typically sent
              when a link is idle

              nacks - Number of negative acknowledgement (NACK) packets sent
              and received by the link

              defs - Number of packets received out of order

              dups - Number of duplicate packets received

       Congestion link
              The number of times an application has tried to send data when
              the TIPC link was congested

       Send queue
              Max is the maximum amount of messages that has resided in the
              out queue during the statistics collection period of a link.

              Avg is the average outqueue size during the lifetime of a link.

   Link properties
       priority
              The priority between logical TIPC links to a particular node.
              Link priority can range from 0 (lowest) to 31 (highest).

       tolerance
              Link tolerance specifies the maximum time in milliseconds that
              TIPC will allow a communication problem to exist before taking
              the link down. The default value is 1500 milliseconds.

       window
              The link window controls how many unacknowledged messages a link
              endpoint can have in its transmit queue before TIPC's congestion
              control mechanism is activated.

EXIT STATUS
       Exit status is 0 if command was successful or a positive integer upon
       failure.
