MIBs
Management and counter information are stored by the 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.
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.
Figure 4- 4. Show switch command
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.
The IP address may be set using the Command Line Interface (CLI) over the console serial
port as follows:
1. Starting at the command line prompt, enter the commands config ipif System
ipaddress xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy. Where the x’s represent the IP address
