Through this MIB, users can setup the device configuration parameters, reset the device, monitor the device’soperational robustness and Quality of Service during run-time, and receive traps.The acBoard MIB has the following groups: boardConfiguration boardInformation channelConfiguration channelStatus reset acTrapThe acBoard MIB is still supported but is being replaced by five newer proprietaryMIBs.
