Step 16
root
Example:
RP/0/RSP0/CPU0:router(config-t3)# root
Exits to global configuration mode.
Step 17
interface serial interface-path-id
Example:
RP/0/RSP0/CPU0:router(config)# interface
serial 0/1/1/0/0/0:0
Specifies the complete interface number with the
rack/slot/module/port/T3Num/T1num:instance notation.
Step 18
encapsulation {frame-relay | hdlc | ppp}
Example:
RP/0/RSP0/CPU0:router(config-if)#
encapsulation ppp
Specifies the encapsulation type with the one of the following
keywords:
• frame-relay—Frame Relay network protocol
• hdlc—High-level Data Link Control (HDLC) synchronous
protocol
• ppp—Point-to-Point Protocol
Step 19
ipv4 ip-address mask
Example:
RP/0/RSP0/CPU0:router(config-if)# ip
address 10.10.10.10 255.255.255.255
Assigns an IP address and subnet mask to the interface.
Step 20
no shutdown
Example:
RP/0/RSP0/CPU0:router(config-if)# no
shutdown
Removes the shutdown configuration.
Note Removal of the shutdown configuration eliminates the
forced administrative down on the interface, enabling it to
move to an up or down state (assuming that the parent
SONET layer is not configured administratively down).
