Just in case someone else has not hit this yet, here's your fair warning.
If you put on a Maintenance Level that includes bos.net.tcp.client
4.3.3.14,
snmp will break and you won't be able to do any sets on anything. This
is most noticeable if you are using MLM. There are later filesets available
but they don't fix the problem. Here's the workaround:
Before you update bos.net.tcp.client to 4.3.3.14, make a copy of the
snmpd binary (/usr/sbin/snmpd). After the update, put this saved copy
back in place.  Any level will do as long as it is less than 4.3.3.14.  If
you
get there without the backup, get one off another sytem.

Cordially,
