Effect Of Vlans (Series 2500 Only) - HP J4818A Installation And Getting Started Manual

Introducing the HP ProCurve Series 2300 and 2500 Switches
Switch Operation Overview
Network Moves and Changes. When a PC, server, printer, or other
network device is moved in the network, and becomes connected to a different
switch port, the Series 2300 and 2500 switches automatically recognize the
change and update their address table with the new port location of the device.
Communication with the device is automatically maintained, without any
address table manipulation being required by the network administrator.
Effect of VLANs
On the Series 2500 switches, 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 broad-
cast domain, just as if it were a separate 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.
