Ip Address Assignment - D-Link xStack DES-3800 Series User Manual

xStack DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch
The Switch allows groups of users to be listed and configured with a shared set of privileges. The
SNMP version may also be set for a listed group of SNMP managers. Thus, you may create a group of
SNMP managers that are allowed to view read-only information or receive traps using SNMP v.1
while assigning a higher level of security to another group, granting read/write privileges using SNMP
v.3.
Using SNMP v.3 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 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 (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
The Switch in 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. 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 example BOOTP, TFTP). The Switch's default IP
address is 10.90.90.90. 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.
