I have configured an SLA Monitor on several of my Cisco routers to determine if a particular circuit or route is available. What is the purpose of the Threshold in the configuration? How low or high should this be set. Along with this, what is the Frequency and how low or high should this be set? I've tried researching this elsewhere but have been unable to find any answers.

IP SLA can be configured to react on certain
conditions. To measure these conditions so IP SLA can react on them it would need to use threasholds. Values you choose for the
threasholds are really dependant on your
particular requirements in your network or
scenario you put together so I can't tell
you exacltly "how low or high high".
Frequency is how often monitor operation
will be executed. Values here are dependant
really on how responsive you want to be if
there is a failure/condition change against
resources available on your router. If CPU &
Memory resources is not an issue you can
decrease the value.

Understood. What I am doing is sending a ping from a remote location back to my data center to make certain the path is up and that the circuit is not down. If the ping fails, the route is to switch to a second data circuit, then switch back once the original comes back on-line. So, based upon what you said, the frequency is how often the pings are sent - I would want this relatively low. In this case, what would the Threshold represent and would it be low or high?

Now if you mean threshold under (config-sla-monitor-echo) then this one used only to
calculate statistics for IP SLA not really to
trigger any action or generate traps. If you
want traps you would have to use reaction-configuration.
