Using SNMP v3 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 SNMP v3 because SNMP
messages may be encrypted. For information about how to configure
SNMP v3 settings for the switch, see Chapter 8, “Simple Network
Management Protocol (SNMP) Commands” on page 155.
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, Topology Change, and Broadcast/Multicast Storm.
MIBs
Management and counter information are stored by the AT-10408XP
switch in the Management Information Base (MIB).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.
