Summary: Discrepancies in SNMPv1 versus v2 traps sent to traphandler

Initial Comment:
SNMPv1 traps do NOT send the sysUpTime or trap OID to
the traphandle script (see below for output) even
though the uptime/trap OID ARE displayed in the console
output.  Also, with snmptrapd run in foreground,
logging to stderr (or stdout), I see the trap come in,
but the traphandle script's output does not get displayed.

Part 1 - the configs:
# cat snmptrapd.conf
traphandle default /usr/bin/tee -a
/usr/local/jffnms/logs/traps.log
Notes:
tee should send the input from the trap both to stdout
as well as appended (-a) to the logfile.

Part 2 - the daemon:
# snmptrapd -C -c ./snmptrapd.conf -f -Le -n -On
2003-12-23 15:53:11 NET-SNMP version 5.1 Started.
Notes: -C makes sure no other conf is read, -f keeps it
in foreground, -Le replaces -P in version 5.1 to log to
stderr, -n=no DNS, -On = numeric OIDs

Part 3 - generate trap:
snmptrap -v 1 -c public localhost enterprises localhost
3 0 '' ifIndex.1 i 1

Part 4 - check for receipt of trap:
This is what the snmptrapd console shows (notice no
script output):
2003-12-23 15:53:11 NET-SNMP version 5.1 Started.
2003-12-23 15:55:04 127.0.0.1(via 127.0.0.1) TRAP, SNMP
v1, community public
        .1.3.6.1.4.1 Link Up Trap (0) Uptime: 1:0
        .1.3.6.1.2.1.2.2.1.1.1 = INTEGER: 1

Part 5 - view log:
This is what is in the logfile (from tee) - notice no
uptime or trap OID... just the linkup OID:
127.0.0.1
127.0.0.1
.1.3.6.1.2.1.2.2.1.1.1 1

Lastly:
If I generate an SNMPv2c trap via:
snmptrap -v 2c -c public localhost 0
.1.3.6.1.6.3.1.1.5.3 .1.3.6.1.2.1.2.2.1.1.1 i 1

I get the correct entry in the log (still not on
snmptrapd console output)
Notice I get Host, IP, UPTIME, TrapOID, and THEN the
linkdown
127.0.0.1
127.0.0.1
.1.3.6.1.2.1.1.3.0 0:0:00:00.00
.1.3.6.1.6.3.1.1.4.1.0 .1.3.6.1.6.3.1.1.5.3
.1.3.6.1.2.1.2.2.1.1.1 1
