- _l_i_n_k_s_t_a_t reports on router link performance and error rates. It also
- reports error rates on the Hub chip Craylink network interface (NI) and
- I/O Interface (II) links.
-
-
- OOOOPPPPTTTTIIIIOOOONNNNSSSS
- ----cccc Report information continuously every five seconds.
-
- ----eeee Only report error rates, not performance information. This option is
- exclusive with ----xxxx.
-
- ----xxxx Only report router ports or hub devices that have non-zero error
- rates. This option is exclusive with ----eeee and only useful when used
- with ----aaaa, ----hhhh or ----rrrr.
-
- ----aaaa Report on all links in the system.
-
- ----hhhh Report only on hub devices.
-
- ----rrrr Report only on router devices.

- To get information about a particular link, you might try something like

- Hub: /hw/module/1/slot/n1/node/hub/mon
- NI: Retries 0 (0/Min), SN errs 0 (0/Min), CB errs 0 (0/Min)
- II: SN errs 0 (0/Min), CB errs 0 (0/Min)
-
- SSSSNNNN eeeerrrrrrrrssss refers to sequence number errors. Some number of these is
- normal. Do not be alarmed by SN error counts. CCCCBBBB eeeerrrrrrrrssss refers to
- checkbit errors. None of these errors are fatal, but high checkbit error
- or retry counts may indicate a problem.

- This example is from a sick system. The checkbit errors on port 5 are
- excessive. All of the other numbers are within spec. Send and receive
- utilizations indicate how much of a port's peak bandwith is being used.
- Bypass indicates what percentage of traffic is able to use the latency-
- reducing bypass feature of the router chip.

- #### lllliiiinnnnkkkkssssttttaaaatttt ----aaaa
-
- This example would display information about all of the links on the
