Methods of Managing the Switch 1000
You can manage the Switch in four ways:
■
Using the VT100 interface by connecting a VT100
terminal (or workstation with terminal emulation
software) to the Switch console port.
■
Using the VT100 interface over a TCP/IP network
using a workstation running VT100 terminal
emulation and Telnet.
■
Using the VT100 interface by connecting a work-
station running SLIP to the Switch console port.
■
Using an SNMP Network Manager over a net-
work running either the IP or IPX protocol. Each
Network Manager provides its own user inter-
face to the management facilities.
Using the VT100 Management Interface
The menu-driven user interface built into the
Switch is known as the
VT100 or Local Manage-
ment interface. The VT100 management interface
provides a forms-based structure with pre-defined
security levels, enabling access to be restricted to
particular users. The Switch can support up to four
management user sessions concurrently (for example
one console port and three Telnet connections).
You can establish VT100 management communica-
tion with the Switch through two different inter-
faces:
■
Via the Console Port — You can access the
local management interface using a VT100 termi-
nal, or PC using suitable terminal emulation soft-
ware. The terminal can be connected directly to
the Switch, or through a modem. You can also
connect a management workstation running SLIP
to the console port, which allows you to use
out-of-band Telnet. The workstation can be con-
nected directly or remotely, through a modem.
This method provides a way of managing the
Switch in situations where the LAN is not provid-
ing a reliable service, where the Network Man-
ager does not have direct LAN connectivity, or
when a Network Manager does not support
SNMP.
■
Via a Network Connection — The local man-
agement facility is also accessible via Telnet over a
network running the TCP/IP protocol. The man-
agement available through Telnet is exactly the
same as that of a locally connected terminal. The
Telnet application requires a VT100 terminal, or
PC using suitable terminal emulation software.
