HI, Thanks Mike for notifying this part. But i have a more generic question now on the logic of updating the MIB entries (such as IF-MIB, IP-MIB etc) to NMS:
There are 2 triggers for updates done to the NMS: 1) Whenever a new network configuration is done, will there be a trigger to update the Container table entries of ifTable and IPAddressTable? 2) Also if there has been no updates for sometime, then a cache-Timer will expire and then trigeers automatic updates? Do both these cases exists, or only the 2nd case of cache_timer only exists for NMS to get updated IF & IP MIB contents? Kindly let me know, so that i can try to handle the timer delays here to overcome this cpu usage issue. Thanks.
