Cisco ASR 9000 Aggregation Services Router Interfaces and Hardware Component Configuration Guide
Purpose
Enters global configuration mode.
Specifies the serial interface name and notation
rack/slot/module/port, and enters interface configuration
mode.
(Optional) Configures the interface encapsulation
parameters and details such as HDLC, PPP or Frame Relay.
The default encapsulation is hdlc.
Note
(Optional) Enters serial submode to configure the serial
parameters.
(Optional) Specifies the length of the cyclic redundancy
check (CRC) for the interface. Enter the 16 keyword to
specify 16-bit CRC mode, or enter the 32 keyword to
specify 32-bit CRC mode.
The default is CRC length is 16.
Note
(Optional) Inverts the data stream.
(Optional) Enables payload scrambling on the interface.
Payload scrambling is disabled on the interface.
Note
(Optional) Specifies a transmit delay on the interface.
Values can be from 0 to 128.
Transmit delay is disabled by default (the transmit
Note
delay is set to 0).
