The MIB module providing configuration and control information for management of hardware modules and components on Cisco devices. The following features are managed: bandwidth oversubscription, clearing of HoL(Head of Line) blocking, etc. Bandwidth oversubscription: a group of ports are said to be operating in bandwidth oversubscription mode if the amount of internal forwarding fabric bandwidth allocated to the group of ports on a switching or routing device is less than the aggregate maximum connection speeds of these ports. Clearing of HoL blocking: refers to the process in which if any port of a port group receives a pause frame from the remote side, it will block packet transmission on all ports of the port group till a packet is delivered to the flow controlled port. If the clearing of HoL blocking feature is disabled, the device will drop packets destined for the jammed ports and continue delivering packets for the other ports.
