CISCO-HW-MODULE-CONTROL-MIB
AI MIB Summary
The CISCO-HW-MODULE-CONTROL-MIB enables configuration and monitoring of hardware module behaviors on Cisco switching and routing platforms, specifically managing bandwidth oversubscription thresholds and Head-of-Line (HoL) blocking clearing mechanisms for port groups. This module allows administrators to control internal fabric bandwidth allocation and override default flow-control pause frame propagation to prevent unnecessary packet drops across active ports during congestion events.
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.

ciscoHwModuleControlMIBThe 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. MODULE-IDENTITY .1.3.6.1.4.1.9.9.714 |
