Configuring forwarding parameters

The following configurable parameters control the forwarding behavior of HP routing switches:

  • Time-To-Live (TTL) threshold

    For more information, see the Management and Configuration Guide for your switch.

  • Forwarding of directed broadcasts

These parameters are global and thus affect all IP interfaces configured on the 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.


[NOTE: ]

NOTE: A less common type, the all-subnets broadcast, goes to all directly-attached subnets. Forwarding for this broadcast type also is supported, but most networks use IP multicasting instead of all-subnet broadcasting.


Forwarding for all types of IP directed broadcasts is disabled by default. You can enable forwarding for all types if needed. You cannot enable forwarding for specific broadcast types.
