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 r eboot ( someone ac cidentally t urned O FF t he S witch), or l ess s erious l ike a por t s tatus c hange. The S witch
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 s tandard MIB-II Management Information Base m odule. C onsequently, v alues f or MIB obj ects c an be r etrieved
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 T CP/IP ap plication ( for ex ample BOOTP, TFTP). The Switch's def ault IP addr ess is 10.90.90.90. You c an
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.

The Switch's MAC address can also be found from the Web management program on the Switch Information (Basic
Settings)
window on the Configuration menu.
The IP address for the Switch must be set before it can be managed with the Web-based manager. The Switch IP
address can be automatically set using BOOTP or DHCP protocols, in which case the actual address assigned to the
Switch must be known.
