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
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.
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.
