1.2 Management Access Overview

The Symbol ES3000 Managed Switch provides user interface flexibility using:
• An administration console
• A Web Browser interface
• External SNMP-based network-management application.
The administration console and Web Browser interface are embedded in the switch firmware.

1.3 SNMP Access

Use an external Simple Network Management Protocol (SNMP) -based application to manage the
Symbol ES3000 Ethernet Switch.
The SNMP management method requires the SNMP agent on the switch and the SNMP Network
Management Station use the same community string and the SNMP Network Management Station
is entered in the SNMP Host table on the switch. The SNMP management method 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 from and write to the MIBs.
However, if it only knows the GET community string, it can only read MIBs. The default GET
community string for the switch is 'public', and the host table is empty.

1.4 Protocols

The Symbol ES3000 Ethernet Switch supports the following protocols:
• Virtual terminal protocols, such as Telnet
• SNMP

1.4.1 Virtual Terminal Protocols

A virtual terminal protocol is a software program (such as Telnet) allowing the establishment of a
management session from a Macintosh, PC or UNIX workstation. Because Telnet runs over TCP/IP, at
least one IP address is required on the ES3000 Ethernet Switch before establishing access to it with
a virtual terminal protocol.
Terminal emulation differs from a virtual terminal protocol in that the user is required to connect a
terminal or PC directly to the console port. A workstation can be connected to the system through a
