Hi all,
     Here is snapshot of my snmpd.conf :

______________________________________________________________
createUser -e 0x8000000001020304 traptest SHA mypassword AES

rouser traptest noauth
agentSecName traptest
iquerySecName traptest

defaultMonitors yes
linkUpDownNotifications yes
________________________________________________________________


I dont get any notification about link up / down from client. I use to check
it by executing command :

#snmptrapd -m all -Le -f -d

The above command shows me notifications when client's snmpd is started /
stopped

I then tried command :

#snmpd -m all -Le -f -d

It showed me some output when my clients  link goes up / down. The snapshot
of output is as follows :

Received 1 bytes from callback: 1 on fd 3
0000: 00                                                    .

              The question is I just want IP address of the client who is
sending this notification. How can i get it? Have I configured my snmp
manager right to receive snmpv3 notifications?
How can I see the Link up/down notification by using command snmptrapd ??
