Interface
The fourth step is to configure a T1 serial interface with an IP address and a crypto
map.
To configure encryption on the T1 channel group, follow this procedure:
For complete information about configuration commands and about configuring
LAN and WAN interfaces on your switch, refer to the Cisco IOS configuration

Task Command
Step 1
Select the serial interface and enter interface
configuration mode.
Gateway (config)# interface serial
slot|port:timeslot
Step 2
Specify an IP address followed by the subnet mask
for this interface.
Gateway (config-if)# ip address
address mask
Step 3
Assign a crypto map to this interface.
Gateway (config-if)# crypto map
map_name
Step 4

Gateway(config)# exit
Step 6
Display the current operating configuration,
including any changes just made.
Gateway# show running-config
Step 7
Display the configuration currently stored in
nonvolatile random-access memory (NVRAM).
Gateway# show startup-config
Step 8
At the enable prompt, write your changes to
NVRAM.
Note The results of the show

startup-config commands differ if you
have made changes to the
configuration but have not yet written
them to NVRAM.
