User Guide for the Avaya P580 and P882 Multiservice Switches, v6.1

Chapter 12

If the forwarding cache contains a high number of short-lived protocol 
entries, you can set the switch to use the slow path to route packets of a 
specific short-lived protocol. By using the slow path to route short-lived 
protocol traffic, you conserve the resources of the forwarding engines, 
which provide the fast in band routing engine (FIRE) and fast out of band 
routing engine (FORE). For information about the slow path and FIRE and 
FORE paths, see “

To configure short-lived protocol filters, your user account must be assigned 
one of the following access types:

■

Read-write

■

Administrator

■

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 
feature is not available in the Web Agent or SNMP. 

This section contains procedures for the following tasks:

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 “

” in 

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: 

(configure)#
