Well, not exactly.

Last I remember, it was changed in 12.2(33)SXH - when the PFC hits
exception on TCAM, it’ll switch “exception” packets (packets to
destination that’s outside of known TCAM programmed entries) with
a mls hardware-limiter set to 10kpps.

In other words - you’re safe, the box won’t melt, but the situation
will require fixing & reload.
