Confirming That the Line Is Up
You can verify that the line is up by performing the following steps:
Step 1 From the privileged EXEC command mode, enter the show interface serial 0
command. You should see command output similar to the following:
Router# show interface serial0
Serial0 is up, line protocol is up
Hardware is QUICC Serial
MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec, rely 255/255, load
1/255

LMI enq sent 163, LMI stat recvd 136, LMI upd recvd 0, DTE LMI up
LMI enq recvd 39, LMI stat sent 0, LMI upd sent 0
LMI DLCI 1023 LMI type is CISCO frame relay DTE
