■
Custom access type that has read-write permission for the routing
feature
You can configure short-lived IP protocol filters only by using the CLI. This

Enabling a Short-Lived IP Protocol Filter
Overview
If you enable a filter for a short-lived IP protocol, the switch uses the slow
path to route packets of the protocol. For information about the slow path,
see “
Routing Overview ” in Chapter 1 , “ Introduction .”
By default a filter is enabled for DNS and NTP packets. To route the
packets of other short-lived protocols by means of the slow path, you must
enable a filter for the protocol.
CLI Command
To enable a filter for a short-lived IP protocol, enter Global Configuration
mode and use the following command:
ip short-lived {tcp | udp} <port>
