Disabling a Short-Lived IP Protocol Filter
Overview If you disable a filter for a short-lived IP protocol, the switch uses either the
fast in band routing engine (FIRE) path or the fast out of band routing
engine (FORE) path to route packets of the protocol. For information about
the FIRE and FORE paths, see “Routing Overview” in Chapter 1,
“Introduction.”.
CLI Command To disable the filter for a short-lived IP protocol, enter Global Configuration
mode and use the following command:
(configure)# no ip short-lived {tcp | udp} <port>
