DES-3528/DES-3552 Series Layer 2 Managed Stackable Fast Ethernet Switch Hardware Installation Guide
Using SNMP v.3 individual use rs or groups of SNMP m anagers can be allowed to pe rform o r be restricted fro m
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 v.3 in that SNMP
messages may be encrypted. To read more about how to configure SNMP v.3 settings for the Switch read the section
entitled Management.
Traps
Traps are messages that alert network personnel of events that occur on the Switch. The events can be as serious as
a reboot (so meone a ccidentally turne d OFF the Switch ), or less se rious like a port st atus ch ange. The Switch
generates traps and se nds them to the trap recipient (or net work manager). Typical trap s include trap messag es for
Authentication Failure, Topology Change and Broadcast\Multicast Storm.
MIBs
The Switch in the Management Information Base (MIB) stores management and counter information. The Switch uses
the standard MIB-II Management Information Base m odule. Consequently, values for MIB o bjects can b e retrieved
from any SNMP-based network management software. In addition to the s tandard MIB-II, the Switch also supports its
own proprietary enterprise MIB as an extended Ma nagement Information Base. Specifying the MIB Object Identifier
may also retrieve the proprietary MIB. MIB values can be either read-only or read-write.
IP Address Assignment
Each Switch must be assigned its own IP Address, which is used for communication with an SNMP network manager
or other TCP/IP application (for exam ple BOOTP, TFTP). The Switch' s default IP address is 10.90.9 0.90. You can
change the default Switch IP address to meet the specification of your networking address scheme.
The Switch is also assigned a unique MAC address by the factory. This MAC address cannot be changed, and can be
found by entering the command "
show switch
" into the command line interface, as shown below.
