My initial test for this used the same software levels as yourself. I
manage a network of around 100 segments, 37 routers and ~ 800 SNMP
managed nodes. My test was to pull the connection between my NetView
system and the first router. From memory, it took around 25 minutes
before I ended up with just 4 entries in TEC - 3 isolated segments and
the root-cause event saying my router was down. This was with an
average 10 minute netmon poll.
If you watch TEC, you see events coming in and then being correlated out
again so you get a quick feel for where the problem might be before (for
me) it came down to the single root cause.
