used to prevent their occurrence, and if that failed, limit
their scope. However, with the advent of VLANs,
switches are now able to limit broadcast domains
better and cheaper than routers. The VH-2402-L3
switch has broadcast sensors and filters built into each
port to control broadcast storms.
IP Routing
IP is responsible for getting packets to the destination
specified in the destination address. The task of
determining how to get a packet from the source to the
destination is referred to as routing.
The VH-2402-L3 allows the creation of IP subnets and
can perform IP routing between them. Each IP subnet
corresponds to an IEEE 802.1Q VLAN, previously
defined on the switch.
