Hi,

I've labbed up your config and It doesn't work. The reason is probably
that the output of 'show ip sla stat 1' shows a timout for the Latest
operation return code.

I've changed the react from connection-loss to timeout.
After changing that I've forced a timeout by shutting down an interface
making the destination unreachable:

Apr 24 20:36:15.543: SNMP: V2 Trap, reqid 7, errstat 0, erridx 0
 sysUpTime.0 = 167920
 snmpTrapOID.0 = rttMonTimeoutNotification
 rttMonCtrlAdminTag.1 =
 rttMonHistoryCollectionAddress.1 = 0A 00 00 01
 rttMonCtrlOperTimeoutOccurred.1 = 1
Apr 24 20:36:15.639: SNMP: Queuing packet to 2.2.2.2

 rttMonCtrlAdminTag.1 =

 rttMonCtrl.19.1.5.1 = 0
 rttMonCtrl.19.1.6.1 = 0
 rttMonEchoAdminEntry.33.1 = 00 00 00 00
Apr 24 20:36:15.795: SNMP: Packet sent via UDP to 2.2.2.2

R1#sh ip sla stat 1

Round Trip Time (RTT) for Index 1
        Latest RTT: NoConnection/Busy/Timeout
Latest operation start time: 20:51:30.587 UTC Tue Apr 24 2007
Latest operation return code: Timeout
Number of successes: 153
Number of failures: 158
Operation time to live: Forever

I'm still looking for a the sla statistics to display connectionloss as
the latest operation return code.

Henk

Hi Group,

I wonder if you could help me.

I am trying to achieve followings

R1 ------ R2 ----------- R3 -- PC(10.0.0.1)

R1 will ping PC(10.0.0.1) using ip sla for reachability if ping fails
then
R1 will send SNMP trap.

R1 ping PC(10.0.0.1) every 5 seconds which is working. But when it can
not
ping, not generating any SNMP trap or log

IS this at all possible. Followings are my config on R1 ( but not
working)
--------------
ip sla monitor responder
ip sla monitor logging traps
ip sla monitor 1
 type echo protocol ipIcmpEcho 10.0.0.1 source-ipaddr 60.0.0.1
 owner admin
 frequency 5
ip sla monitor reaction-configuration 1 connection-loss-enable
threshold-falling 5000 action-type trapAndTrigger
ip sla monitor reaction-trigger 1 3
ip sla monitor schedule 1 life forever start-time now

!
snmp-server enable traps rtr
snmp-server enable traps syslog
snmp-server host 1.1.1.1 cisco rtr
_____________--

I have done "debug Snmp packets" but can not see any match.

Your help will be highly appreciated.

Thanks
