Configuring Forwarding Parameters

The following configurable parameters control the forwarding behavior of
ProCurve routing switches:
Time-To-Live (TTL) threshold
■
■ Forwarding of directed broadcasts
All these parameters are global and thus affect all IP interfaces configured on
the routing switch.
To configure these parameters, use the procedures in the following sections.

Changing the TTL Threshold

The configuration of this parameter is covered in the chapter titled, "Config­
uring IP Addressing" in the Management and Configuration Guide for your
routing switch.

Enabling Forwarding of Directed Broadcasts

A directed broadcast is an IP broadcast to all devices within a single directly-
attached network or subnet. A net-directed broadcast goes to all devices on a
given network. A subnet-directed broadcast goes to all devices within a given
subnet.
