Disabling a Short-Lived IP Protocol Filter

Overview
Part No. 610-0229-091
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,"
of the Avaya P550R, P580, P880, and P882 Multiservice Switch User
Guide, Version 5.3.1.
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.
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>
Table 1. Keywords, Arguments, and Options
Keyword, Argument,
or Option
{tcp | udp}
<port>
To send all SNMP packets to supervisor module for slow path
routing, enter the following command:
ip short-lived udp 161
To send all BOOTP and DHCP packets to the supervisor for slow path
routing, enter the following command:
ip short-lived udp 67
ip short-lived udp 68
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.
