Simultaneous Network Communications; Effect Of Vlans - HP ProCurve 1600M Installation Manual

Introducing the HP ProCurve Switch 1600M and 2424M
Switch Operation Overview

Simultaneous Network Communications

As part of the traffic isolation benefits provided by the Switch 1600M and
2424M address table operation, the switches enhance network performance
because they can conduct multiple, simultaneous network connections.
Instead of sharing the network bandwidth, as in connections to a hub, each
connection has its own 10 Mbps, 100 Mbps, or 1000 Mbps bandwidth to use.

Effect of VLANs

If you configure multiple virtual LANs (VLANs) on the switch, each VLAN
behaves as a "logical switch" containing the switch ports that you assign to it.
Each logical switch behaves as an isolated broadcast domain, just as if it were
an isolated physical switch. The forward, filter, and flood behavior described
for the physical switch above, operates the same for each of the logical
switches defined by the VLANs: packets are forwarded or flooded only to the
ports that are within a given VLAN. Just as for separate isolated physical
switches, there is no communication between ports that are in separate VLANs
unless the VLANs are connected by an external router.
For more information on configuring VLANs and their behavior, see the
Management and Configuration Guide that came with your switch.
