Chapter 3: Switch Management
You can change these settings, if desired, after you log on. This management method
is often preferred because you can remain connected and monitor the system during
system reboots. Also, certain error messages are sent to the serial port, regardless of
the interface through which the associated action was initiated. A Macintosh or PC
attachment can use any terminal-emulation program for connecting to the terminal
serial port. A workstation attachment under UNIX can use an emulator such as TIP.

Protocols

The Managed Switch supports the following protocols:
• Virtual terminal protocols, such as Telnet
• Simple Network Management Protocol (SNMP)
Virtual Terminal Protocols (Telnet)
A virtual terminal protocol is a software program, such as Telnet, that allows you to
establish a management session from a Macintosh, a PC, or a UNIX workstation.
Because Telnet runs over TCP/IP, you must have at least one IP address configured
on the Managed Switch before you can establish access to it with a virtual terminal
protocol.
Terminal emulation differs from a virtual terminal protocol in that you must connect a
terminal directly to the console (serial) port.
NOTE: See the Installation Sheet that came with this product for a Telnet step-by-
step procedure using Hyper Terminal.
To access the Managed Switch through a Telnet session:
1. Be Sure of the Managed Switch is configured with an IP address and the Managed
Switch is reachable from a PC.
2. Start the Telnet program on a PC and connect to the Managed Switch.
The management interface is exactly the same with RS-232 console management.
SNMP Protocol
Simple Network Management Protocol (SNMP) is the standard management protocol
for multi-vendor IP networks. SNMP supports transaction-based queries that allow
the protocol to format messages and to transmit information between reporting
