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.
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 so ftware program, such as Telnet, that allows
you to establish a management session from a M acintosh, 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.
