Description of Hardware
For communications between different VLANs, this switch uses IP routing. For
communications within the same VLAN, the switch uses store-and-forward
switching to ensure maximum data integrity. With store-and-forward switching,
the entire packet must be received into a buffer and checked for validity before
being forwarded. This prevents errors from being propagated throughout the
network.

ETWORK
ANAGEMENT
This switch contains a comprehensive array of LEDs for "at-a-glance" monitoring
of network and port status. It also includes a management agent that allows you
to configure or monitor the switch using its embedded management software, or
via SNMP applications. To manage the switch, you can make a direct connection
to the console port (out-of-band), or you can manage it through a network
connection (in-band) using Telnet, the on-board web agent, or SNMP-based
network management software.
The Managementt port (RJ-45) provides a dedicated management channel that
operates outside of the data transport network. This makes it possible to re-
configure or troubleshoot the switch over either a local or remote connection to
the Management port when access through the data channel is not possible or
deemed insecure.
For a detailed description of the switch's software features, refer to the
Management Guide.
