Another example is to print all objects exported by switch.
@smallexample
snmpwalk -c public -v 2c wrs -m all \

@c ==========================================================================
@node show-pstats
@section show-pstats
To visualize all port statistics in a single window, this package
includes the simple tool @t{userspace/snmpd/show-pstats}. It is
a Tk script, so you need to install @t{tk8.5} or any other version.
The script receives one or more host names (or IP addresses) on the command
line. They must refer to a switch (or switches) or the program fails like this:
@smallexample
laptopo% ./show-pstats morgana
Error in snmpwalk for host morgana
No log handling enabled - using stderr logging
.1.3.6.1.4.1.96.100.2.1.: Unknown Object Identifier (Sub-id not found: enterprises -> )
@end smallexample
If everything goes well, you'll get a window like the following one:
@center @image{show-pstats, 10cm,, show-pstats}
Command @t{snmptable} can also be used to get simillar results:
@smallexample
snmptable -Cw 80 -c public -v 2c 192.168.1.10 -m all \
-M $WRS_OUTPUT_DIR/build/buildroot-2016.02/output/build/netsnmp-5.7.3/mibs/\
:userspace/snmpd/ WR-SWITCH-MIB::wrsPstatsHCTable
@end smallexample
Output is in text form and looks like:
@smallexample
SNMP table: WR-SWITCH-MIB::wrsPstatsHCTable
wrsPstatsHCPortName wrsPstatsHCTXUnderrun wrsPstatsHCRXOverrun

Unfortunately output due to the number of counters is very wide. Number of
characters per line can be limited by switch @t{Cw}, in example was set to 80.

@appendix Bugs and Troubleshooting
Even if the package is already released and used in production,
some details can be
suboptimal, while some procedures may be tricky and need more explanation.
We are collecting all those issues in the @i{wiki} page of the
project, to avoid frequent updates to this manual to just collect
those details. So please visit
@url{www.ohwr.org/projects/wr-switch-sw/wiki/Bugs} and
@url{www.ohwr.org/projects/wr-switch-sw/wiki/Troubleshooting}
if you have any problem with this package, but feel free to reach us
on the mailing list if you don't find help there.
