No, it does no such thing. Nagios has no idea what your links are unless
you tell it. There's a check_ping command that takes two arguments for
its Warning and Critical thresholds. Adjust as needed. To keep things
simple, I'd check everything on that side of the link with a custom
"check_ping_oxford" that sets those variables for you - if you find
they're too low, you'll only have to change them once.

Use the check_interval and retry_interval to adjust upwards until your
false-positives go away.
