Step 4 Define the slot/port group range of the interface. The range that you specify depends on the number of asynchronous interfaces you have on your gateway. If your gateway has 108 asynchronous interfaces, you can specify
Building configuration...
Step 5 Return to privileged EXEC mode:
Gateway#
Tip To save the gateway configuration, save it to NVRAM. See the “Saving Configuration Changes” section on page 60.
Verifying the Group Interface Configuration
To verify your group interface configuration, enter the show interface async command in privileged EXEC mode:
Gateway# show interface async 4/0
Async4/00 is down, line protocol is down modem(slot/port)=4/0, state=IDLE dsx1(slot/unit/channel)=NONE, status=VDEV_STATUS_UNLOCKED Hardware is Async Serial

If you are having trouble, check for errors as well as local and remote addresses. Enter the show async status command in privileged EXEC mode:
