D-Link DES-1228/ME User Manual - Traps
DES-1228/ME Layer 2 Fast Ethernet Managed Switch

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.
