Description
This installation guide describes Enterasys Networks’ Vertical Horizon
VH-8TX1UM/VH-8TX1MF Fast Ethernet switch. The switch provides 7
fixed 10Base-T/100Base-TX ports, plus an eighth port which can be
selected between 10/100Base-TX and 100 Base-FX multi-mode or
single-mode fiber. There is also a fixed SNMP-based management card
included in the switch. This management card supports 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 switch can connect up to 8 end-node workstations or servers using
its 10/100Base-TX ports. Moreover, you can use the 100Base-FX fiber
port for connecting to a remote site.
The RMON/SNMP/Web management card 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 management card
also supports Remote Monitoring (RMON) for Statistics, History, Alarm
and Event groups (Groups 1-3, 9).
Network management can be performed in-band using a TCP/IP or Telnet
connection to the switch. This card 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, terminal, or
modem connection.
