3SETTING UP FOR MANAGEMENT

Methods of Managing the Switch 3000 TX

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 managemen t facilities.

Using the VT100 Management Interface

The menu-driven user interface built into the

Switch is known as the VT100 or local ma nage-

ment interface. The VT100 management interface

gives a forms-based structure with pre-defined secu-

rity levels, enabling access to be restricted to partic-

ular users.

The Switch can support up to four management

user sessions concurrently (for example, one con-

sole 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 via a modem. You can also con-

nect 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, via a modem. This

method provides a way of managing the Switch

in situations where the LAN is not providing a

reliable service, or where the Network Manager

does not have direct LAN connectivity or when a

Network Manager does not support SNMP.

■Via a Network Connect ion — 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 with VT100 emulation software.
