linkup linkdown monitoring impacts the performance

[siddesh.rajappa]

Hi,        I am using net-snmp-5.2.1 in power-pc, To send linkup and linkdown traps, the following configuration has been made in snmpd.conf file.   linkUpDownNotifications yes monitor  -r 5 -e linkUpTrap   "Generate linkUp" ifOperStatus != 2 monitor  -r 5 -e linkDownTrap "Generate linkDown" ifOperStatus == 2        Since this set-up makes frequently so many system calls (i had monitor the snmpd process using strace ) , it affects the devices thruput rate. If i run snmpd, with this configuration thruptput is reduced to very low rate, where as if i run the snmpd by commenting out the monitor line, the device throughput rate is fine (after the initialization no system calls has been made, if no request is send to snmpd).        Is there a way, to send the linkup/linkdown trap, with out configuration monitor line ( with out making lot of system calls frequently) ?    Regards, Kanda
