The administrative system control status of LLDP
module. The value 'start' (1) indicates that all
resources required by LLDP module should be allocated
and LLDP should be supported in the device on all ports.
The value 'shutdown' (3) indicates that LLDP should be
shutdown in the device on all ports and all allocated
memory must be released.
Here, start and shutdown are configurable values.
shutdownInProgress can only be read and cannot be wriiten.
When 'shutdown' (3)is configured, the value is changed to
'shutdownInProgress' (2). This is because shutdownInProgress
is used to indicate that shutdown process has been initiated
by setting the object as shutdown but the process is not
comitted. The value should be changed to shutdown once
LLDP is shut on all ports and memory is released.
