C.13.1.3 Manager Gets Deregistered
The Manager keeps getting de-registered from RtmProxy after a while
Step 1 Verify that the Keep Alive script is running. The manager will automatically get de-registered if no snmp
is done on any of the tables in RtmProxy. To keep the manager registered with RtmProxy, run the keep
alive script in the background, as follows:
#!/bin/sh
Usage="$0 <Agent Ip Address> <Manager IP address>"
if [ $# -lt 2 ]
then
echo "Usage :$Usage"
exit 1
fi
managerRowStatus=.1.3.6.1.4.1.351.120.1.1.1.3
managerPortNumber=.1.3.6.1.4.1.351.120.1.1.1.2
lastseq=.1.3.6.1.4.1.351.120.1.3.0
while true
do
sleep 60
CMD="/opt/OV/bin/snmpget -cpublic -p8161 -t3000 -r0 $1 $managerRowStatus.$2 $lastseq"
echo $CMD
$CMD
done
exit 0
Step 2 Verify that ip reachablity is not lost of the Cisco MGM station from the station where the manager is
running.
