encapsulation. You can also choose PPP or HDLC.
Router(config-if)# encapsulation frame-relay
If IP routing is enabled on the system, you can assign an IP address and subnet mask. For example:
Step 5
Router(config-if)# ip address 172.16.32.49 255.255.0.0
Add any configuration subcommands required to enable routing protocols and set the interface line

characteristics.
Change the shutdown state to up, which enables the interface.
Step 7
Router(config-if)# no shutdown
When you have entered all of the configuration subcommands to complete the configuration, press
Step 8
Ctrl-Z to exit configuration mode.
Write the new configuration to NVRAM.
Step 9
Router# copy running-config startup-config
After you create an interface configuration, you can modify it at any time by using the appropriate Cisco
IOS configuration commands.

Enter controller configuration mode.
Router(config)# controller t3 2/0/0.4
Router(config-controller)#
Use the t1 channel group command to create fractional T1 interfaces. In the following example, T1
interface 3 (of 28) is defined as being made up of three channel groups, numbers 19, 20, and 21 (any
numbers between 0 and 23). The channel groups consist of a total of 24 DS0 timeslots. Each channel
group represents a separate interface.
Router(config-controller) t1 3 channel-group 19 timeslots 1-6, 10
Router(config-controller) t1 3 channel-group 20 timeslots 7,8,9
Router(config-controller) t1 3 channel-group 21 timeslots 11-24
Go to interface configuration mode for one of the channel groups. For example:
Router(config)# interface serial 2/0/0.4/3:19
Go to Step 4.
12 STM-0 controllers. Each STM-0 controller can be configured as one AU-3 controller, each of
which can be configured a T3 interface or as 28 T1 interfaces or 21 E1 interfaces. These interfaces
can be channelized into fractional T1s or E1s.
4 STM-1 controllers. Each STM-1 controller can be configured with three AU-4-TUG-3 controllers,
each of which can be configured as 28 T1 interfaces or up to 21 E1 interfaces. These interfaces can
be channelized into fractional T1s or E1s.
