Web Management
The switch provides a browser interface that lets you configure and manage the switch
remotely.
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
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 Network 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 get and set community strings for the switch are public.
Protocols
The 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 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 is different from a virtual terminal protocol in that you must
connect a terminal directly to the console port.
SIMPLE NETWORK MANAGEMENT PROTOCOL (SNMP)
SNMP is the standard management protocol for multivendor 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.
