Description
This installation guide describes Enterasys’ VH-8G Gigabit Ethernet
switch. This switch provides 8 1000Base-SX ports and includes an
SNMP-based management agent with support for both in-band and out-
of-band access for managing the switch.
The switch employs a high-speed switching fabric. This design allows for
simultaneous transport of multiple packets at low latency on all ports. It
also uses store-and-forward switching to ensure maximum data integrity.
In this mode, the entire packet must be received into a port buffer and
checked for validity before being forwarded. This prevents errors from
being propagated throughout the network. This switch also features full-
duplex capability on all ports, which effectively doubles the bandwidth of
each connection.
The RMON/SNMP/Web management agent provides a broad range of
management options. It includes a standards-compliant Simple Network
Management Protocol (SNMP) agent. The SNMP agent allows network
management station applications to collect and present status and
performance information about the switch, as well as providing the ability
to configure and control functions in the switch. The SNMP agent also
supports Remote Monitoring (RMON) for Statistics, History, Alarm and
Event groups (Groups 1-3, 9).
Network management can be performed in-band using TCP/IP or Telnet
connection to the serial console port on the switch’s rear panel. The
switch also includes a built-in Web agent that provides management
access via common http browsers such as Netscape Navigator and
Microsoft’s Internet Explorer. In addition, the console port allows out-of-
band management using a PC or terminal.
This switch also provides support for a Redundant Power Unit to ensure
continuous operation in the event of a power failure.
The VH-8G switch is desktop or rack-mountable. LEDs on the front panel
provide information about the operating status of the switch. The rear
panel contains the power connector, redundant power connector, and the
serial console port. The side panel includes two fans that maintain
ventilation and cooling for internal switch components.
