Black Box 8-port 10/100base-tx hardened ethernet extender switch SNMP-Based Network Management

Chapter 4: Hardened Ethernet Extender Switch Management

After you set up your IP address for the Hardened Ethernet Extender Switch, you can access the Hardened Ethernet Extender Switch’s Web interface applications directly in your Web browser by entering the IP address of the Hardened Ethernet Extender Switch. You can then use your Web browser to list and manage Hardened Ethernet Extender Switch configuration parameters from one central location, just as if you were directly connected to the Hardened Ethernet Extender Switch’s console port.

4.4 SNMP-Based Network Management

You can use an external SNMP-based application to configure and manage the Hardened Ethernet Extender Switch. This management method requires the SNMP agent on the Hardened Ethernet Extender Switch and the SNMP Network Management Station to use the same community string. This management meth- od uses two community strings: the get community string and the set community string. If the SNMP Network management station only knows the set community string, it can read and write to the MIBs. However, if it only knows the get com- munity string, it can only read MIBs.

NOTE: The default get and set community strings for the Hardened Ethernet Extender Switch are public.

4.5 Protocols

The Hardened Ethernet Extender Switch supports the following protocols:

Virtual Terminal Protocols, such as 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 worksta- tion. Because Telnet runs over TCP/IP, you must have at least one IP address con- figured on the Hardened Ethernet Extender Switch before you can establish access to it with a virtual terminal protocol.

NOTE: Terminal emulation is different from a virtual terminal protocol. In emulation, you must connect a terminal directly to the console port, but a virtual terminal protocol does not require direct connection.
