Here is a summary and compilation of some good DCF technotes that list some questions and answers regarding ISM (Internet Service Monitoring) Agent environment.
This is part 5 of this blog.
Q) Why my ism rping monitor is failing and returns : "no response received", with CISCO device?
A) The unit of time for CISCO routers is different from RFC2925 and Juniper. The unit of time on CISCO is in millisecond, but in seconds on Juniper and RFC2925.
Setting packettimeout to 500 (seconds) exceeds the allowable range on Juniper based systems. Instead, the range of the Packet Timeout should be between 1 and 60 (seconds).
A customer was experiencing issue with his ISM RPING monitor against some Cisco devices, and he changed in his ISM profile's monitor setting:
packettimeout = 500
packettimeout = 10
and it helped.
so reducing the default value of packettimeout parameter is something to consider, even with Cisco device.
