attachment under UNIX can use an emulator such as TIP.
3.2 Web Management
The switch provides a browser interface that lets you configure and manage the switch
remotely. After you set up your IP address for the switch, you can access the switch’s Web
interface applications directly in your Web browser by entering the IP address of the switch.
You can then use your Web browser to list and manage switch configuration parameters
from one central location, just as if you were directly connected to the switch’s console
port.
Web Management requires either Microsoft Internet Explorer 4.01 or later or Netscape
Navigator 4.03 or later.
3.3 SNMP-Based Network Management
You can use an external SNMP-based application to configure and manage the switch.
This management method requires the SNMP agent on the switch and the SNMP Network
Management Station to use the same community string. This management method, in fact,
uses two community strings: the get community string and the set community string. If the
SNMP Net-work management Station only knows the set community string, it can read
and write to the MIBs. However, if it only knows the get community string, it can only read
MIBs. The default gets and sets community strings for the switch are public.
3.4 Protocols
The switch supports the following protocols:
z
Virtual terminal protocols, such as Telnet
z
Simple Network Management Protocol (SNMP)
3.4.1 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 switch
before you can establish access to it with a virtual terminal protocol.
Note:
Terminal emulation differs from a virtual terminal protocol in that you must connect a
terminal directly to the console (serial) port.
3.4.2 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 devices and data-collection
programs. SNMP runs on top of the User Datagram Protocol (UDP), offering a
connectionless-mode service.
