I presume you're thinking here of the 3800/4500 series from Acme, not the 2600.

In which case, on a session agent max-burst-rate and max-sustain-rate
will both limit the sessions and deny any session over the limits but
will not demote the host into the untrusted queue. You can also
configure the wndows using burst-rate-window and sustain-rate-window.
Note that you have to have constraints enabled on the session-agent
for these values to take effect. Note that if the traffic triggers the
realm DoS settings, it will demote the host whereas the SA settings
won't. If you want to force the demotion, you can use an ACL to do so
(e.g. maximum-signal-threshold in session-router access-control).

Was that what you were looking for?

Thanks,
Aled.
