IP SLA is the first thing to come to mind for identifying the trouble point(s) in the LAN space when experiencing sluggish response browsing an external website. I assume a basic "http get" is ok for simulating the web browsing, but what is the best option with IP SLA for identifying where the trouble spot is within the LAN space? Would that be the ICMP Path Echo Operation? If I use a third-party tool that measures web site response, would it be possible to kick off ICMP Path Echo Operation on-demand only when there's an identified slow response by that other tool? Is issuing snmpset to the IP SLA router(s) the only means of doing that?
Is CiscoWorks IPM a frontend performing the same steps in the background as outlined in these examples? Is it performing these configs on the routers only with snmpsets? Is it possible to trigger another IP SLA operation upon the "http get" operation hitting a certain response, via IPM or on the router directly, without the benefit of facilities such as EEM?
