LMI enq sent  15, LMI stat recvd 16, LMI upd recvd 0, DTE LMI up
LMI enq recvd 0, LMI stat sent  0, LMI upd sent  0
LMI DLCI 0  LMI type is ANSI Annex D  frame relay DTE
Broadcast queue 0/64, broadcasts sent/dropped 6/0, interface broadcasts 0
Last input 00:00:01, output 00:00:01, output hang never
Last clearing of “show interface” counters never
Input queue: 0/75/0 (size/max/drops); Total output drops: 0
Queueing strategy: weighted fair
