3.1 Managing the Switch

This chapter describes the following switch management functions:
• Configuring Simple Network Management Protocol (SNMP)
• Viewing port counters
• Saving configuration changes
• Updating the switch software
• Rebooting the switch

3.2 SNMP

3.2.1 Overview

Simple Network Management Protocol (SNMP) is a messaging protocol that allows communication
between network managers and agents. An SNMP manager is part of a network management system
(NMS), and allows the administrator to manage the network by making requests to agents. An SNMP
agent provides an interface to a managed device, which contains managed objects in a management
information base (MIB).
At the request of an SNMP manager, an SNMP agent retrieves or stores values in the device
described in the MIB. The SNMP agent can also send asynchronous traps, which alert the SNMP
manager to certain conditions on the network. A trap might result from improper user authentication,
PoE power usage over threshold, or network topology changes, for example.
In the ES3000 switch, the agent and the MIB reside on the switch. To configure SNMP on the switch,
the administrator sets up the relationship between the agent and the SNMP managers.
The ES3000 switch supports the following standard MIBs:
BRIDGE-MIB
IEEE8021-PAE-MIB
IEEE8023-LAG-MIB
IF-MIB
IP-MIB
P-BRIDGE-MIB
RADIUS-AUTH-CLIENT-MIB
RADIUS-ACC-CLIENT-MIB
RFC123-MIB
RMON-MIB
SNMPv2-MIB
TCP-MIB
