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.
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: 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.
