This MIB module provides the ability for a Network
Management Station (NMS) to configure and monitor the
error-disable feature via SNMP.
        
The error-disable feature allows other software
features running in a system to operationally disable a
system entity upon detecting abnormal conditions. 
        
Examples of such a system entity include interfaces, a
vlan configured in the system, or a VLAN allowed on
specific layer 2 multi-vlan interface.
        
More specific examples:
        
    a) When BPDU guard is enabled on an interface
    it is expected that no BPDU packets are received by
    the interface. If a BPDU packet is received, then the
    BPDU guard will operationally disable the
    interface. 
        
    b) Users can configure a particular threshold of
    broadcast packets received on an interface. If the
    number of packets received exceeds the threshold, then
    storm-control will disable the interface. 
        
    c) When unidirectional Link Detection (UDLD) detects a
    unidirectional link on an interface, it can disable
    the interface.
        
    d) On a trunk or a multi-vlan layer 2 port, if
    port-security detects violation on a particular vlan,
    then it can operationally disable that vlan on that
    port.
        
The definition of 'abnormal condition' is under the
control of features that make use of the error-disable
feature to disable system entities.
        
The error-disable feature supports the following
configuration:
        
    1) Whether software features can in fact use the
    error-disable feature upon detecting abnormal
    conditions.
       NOTE: Some software features will ALWAYS use the
       error-disable feature to disable entities upon
       detection of error.
        
    2) Whether the system can attempt to automatically
    recover after a system entity has been disabled (e.g., 
    A system can attempt to bring up a physical interface
    which had been disabled earlier)
        
    3) If error recovery is possible, then the time
    interval to wait before the system starts the recovery
    attempt.
