Each port will have one or more associated virtual circuits. This column tells you the current 
status of 

Data 

virtual circuits. These counts do not apply to management virtual circuits. The 

first number is the number of active 

VCs

 and the second is the number of inactive 

VCs

. An 

 virtual circuit is one that is operationally Up and capable of transmitting data; it may 

not necessarily be transmitting at this time. An 

 virtual circuit is present, but for some 

reason is operationally Down. It is not capable of passing data because either its administra-
tive status was set to Down or the Frame Relay network indicated it was present but Down.
