CISCO-HW-MODULE-CONTROL-MIB

        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.

Net-SNMP examples using the cisco MIB directory Show commands

These commands use the standard Observium installation path and load the selected MIB variant before the RFC and Net-SNMP directories.
