I did a TCPDUMP and found tht the traps do reach the server from the router
...bit of relief !!! :-)))
But the server sends back a icmp request to the router and reports that the
udp port is unreachable ...
Here's the output of TCPDUMP
11:23:36.745041 172.25.63.23.55549 > inatpuxpms01.snmptrap:
C=permitadp Trap(36) E:cisco.1.110 172.25.63.23 linkDown
501199095 .iso.org.dod=[|snmp]
172.25.63.23 --> router
inatpuxpms01 -> server
and then the error in the next line
11:23:36.745049 inatpuxpms01 > 172.25.63.23: icmp: inatpuxpms01 udp port
snmptrap unreachable [tos 0xc0]
Iam sort of confused y this error comes .... When i do the same in other
server ( which receives traps successfully )) the 2nd line is not there..
is tht anything to do with snmpconf ??? shud we change any default options
???
Thanks in advance

Trapsinks are for the agent (snmpd) sending traps. He's talking about
receiving
traps (snmptrapd) from another box...
The first thing I'd check is if snmptrapd is receiving the packets. Run it
iin the foreground with packet dumping on:
snmptrapd -f -Le -d
Then generate the traps and see if the incoming packet is printed. If not,
then
I'm guessing that you have a firewall running which is blocking the
packets.
You need to open up UDP port 162 to receive traps.
