A MIB to configure the Port-Track feature.

When a link goes down, all the services which depend 
on the link are notified of the outage. The loss of
this link may be an indirect failure to the end devices 
attached to the switch. The concept behind the Port-Track  
feature is to create a direct failure on the ports  
connected to end devices on event of such indirect 
failures.

One more ports can be 'tracked' in terms of their 
operational status. The cptPortTrackTable lets the user
associate which port(s) need to be tracked to the ports 
that will be tracking them. 

cptPortForceShutTable, lets the user configure the 
forced-shut mode of the linked-port.
