A misleading load of rubbish about network speed settings.
You set your Network Interface Card speed to match the speed of the switch - agree it with the network administrator and get them to force the switch port too. You may have to delete and rediscover the card to be able to do it, so it's not a trivial task and it is unrelated to this issue in my expectation.
I have had this very problem, and on AIX too. DNS is the most likely issue. If you have multiple DNS servers defined, then you would think that if the first one listed in /etc/resolv.conf does not respond that you will move on to the next. Whilst this is true, the default is to try again a few times and the timeout is a few seconds. By default, this adds up to 75 seconds.
We changed our /etc/environment to add the following two records:-
That brings to timeout down to 4 seconds.
Give that a try and see if it helps. You may also want to check your DNS servers are all responding properly. For each defined server, use a series of nslookups with the DNS server's IP address appended to force it. That may illustrate something else too.
HI All,
Does anyone out there know of any good online tutorials for the basics of routing, gateways, networking with AIX, preferably the more recent versions like 5.2/5.3?

Hi all,
From Googling, I found that the basics used for troubleshooting UNIX/AIX performance issues are commands like vmstat, iostat and sar. I believe these are generic commands regardless of what UNIX flavour is in used, only difference being is the format of the output.

captoinfo
captoinfo(1) General Commands Manual captoinfo(1)NAME
captoinfo - convert a termcap description into a terminfo description
SYNOPSIS
captoinfo [-vn width] [-V] [-1] [-w width] file . . .
DESCRIPTION
captoinfo looks in file for termcap descriptions. For each one found, an equivalent terminfo description is written to standard output.
Termcap tc capabilities are translated directly to terminfo use capabilities.
If no file is given, then the environment variable TERMCAP is used for the filename or entry. If TERMCAP is a full pathname to a file,
only the terminal whose name is specified in the environment variable TERM is extracted from that file. If the environment variable TERM-
CAP is not set, then the file /usr/share/terminfo is read.
-v print out tracing information on standard error as the program runs.
-V print out the version of the program in use on standard error and exit.
-1 cause the fields to print out one to a line. Otherwise, the fields will be printed several to a line to a maximum width of 60 charac-
ters.
-w change the output to width characters.
FILES
/usr/share/terminfo Compiled terminal description database.
TRANSLATIONS FROM NONSTANDARD CAPABILITIES
Some obsolete nonstandard capabilities will automatically be translated into standard (SVr4/XSI Curses) terminfo capabilities by captoinfo.
Whenever one of these automatic translations is done, the program will issue an notification to stderr, inviting the user to check that it
has not mistakenly translated a completely unknown and random capability and/or syntax error.
XENIX termcap also used to have a set of extension capabilities for forms drawing, designed to take advantage of the IBM PC high-half
graphics. They were as follows:
If the single-line capabilities occur in an entry, they will automatically be composed into an acsc string. The double-line capabilities
and GG are discarded with a warning message.
IBM's AIX has a terminfo facility descended from SVr1 terminfo but incompatible with the SVr4 format. The following AIX extensions are
automatically translated:
Additionally, the AIX box1 capability will be automatically translated to an acsc string.
Hewlett-Packard's terminfo library supports two nonstandard terminfo capabilities meml (memory lock) and memu (memory unlock). These will
be discarded with a warning message.
NOTES
This utility is actually a link to tic(1), running in -I mode. You can use other tic options such as -f and -x.
The trace option is not identical to SVr4's. Under SVr4, instead of following the -v with a trace level n, you repeat it n times.
