line, type the pre-set password (the factory default is “admin”). Type
“?” and press the “enter” key for a list of the main commands. As shown above, the “list”
command has been entered below the last main command listed.
2.1.3 snMP-based Management and settings
You can manage the Managed layer 3 Access Switch with SNMP Manager software (referred
to as an agent) that runs locally on the device. The SNMP agent decodes the incoming SNMP
messages and responds to requests with MIB (Management Information Base) objects that
are defined and stored in the database. The SNMP agent updates the MIB objects to generate
statistics and counters.
The Simple Network Management Protocol (SNMP) is an application layer specifically designed
for managing and monitoring network devices. SNMP enables network management stations
to read and modify the settings of gateways, routers, switches and other network devices. Use
SNMP to configure system features for proper operation, to monitor performance and to detect
potential problems in the switch, switch group or network.
In short, SNMP defines both the format of the MIB specifications and the protocol used to
access this information over the network.
2.1.3.1 MIB Objects
The Management Information Base (MIB) stores management and counter information. The
switch uses the standard MIB-II Management Information Base module, so, consequently,
values for MIB objects can be retrieved from any SNMP-based network management software.
MIB values can be either read-only or read-and-write.
2.1.3.2 Traps
Traps are messages that notify network personnel of events that occur on the switch. The events
can be as serious as a reboot (someone accidentally turns the switch off) or as minor as a port
status change. The switch generates traps and sends them to the trap recipient (or network
manager). Typical traps include trap messages for Authentication Failure, Topology Change
and Broadcast/Multicast Storm.
