SNMPv3 uses a more sophisticated authentication process that is separated into two parts.
1. The first part is to maintain a list of users and their attributes that are allowed to act as SNMP managers.
2. The second part describes what each user on that list can do as an SNMP manager.
The switch allows groups of users to be created and configured with a shared set of privileges. The SNMP version
may also be configured for a specific group of SNMP managers. A group of SNMP managers can be created to view
read-only information or to receive traps using SNMPv1 while assigning a higher level of security to another group,
granting read/write privileges using SNMPv3.
Using SNMPv3, individual users or groups of SNMP managers can be allowed to perform or be restricted from
performing specific SNMP management functions. The functions allowed or restricted are defined using the Object
Identifier (OID) associated with a specific MIB. An additional layer of security is available for SNMPv3 in which SNMP
messages may be encrypted.

Traps

Traps are messages that alert network personnel of events that occur on the switch. The events can be as serious as
a reboot (someone accidentally turned OFF the switch), or less serious like 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, and Topology Change.

Management Information Base (MIB)

The Management Information Base (MIB) stores management and counter information. The switch uses the standard
MIB-II Management Information Base module. Consequently, values for MIB objects can be retrieved from any
SNMP-based network management software. In addition to the standard MIB-II, the Switch also supports its own
proprietary enterprise MIB as an extended Management Information Base. The proprietary MIB may also be retrieved
by specifying the MIB Object Identifier. MIB values can be either read-only or read-write.

Connecting using the Web User Interface

Only some software functions of the switch can be managed, configured, and monitored via the embedded Web-
based (HTML) interface. This can be done from any remote station on the network through a standard web browser,
such as Internet Explorer (version 6.0 and later), Mozilla Firefox (version 3.0 and later), Safari (version 4.0 and later),
Google Chrome (version 5.0 and later), Opera (version 9.0 and later), or Netscape (version 7.0 and later). The
browser acts as a universal access tool and can communicate directly with the switch using the HTTP protocol.
The Command Line Interface provides the functionality of managing, configuring, and monitoring all of the software
features that are available on this Switch.
