5. Set the CRC length.
crc { 16 | 32 }
Optional.
The default is 32 bits.
6. Set the loopback mode.
loopback { local | remote }
Optional.
Loopback is disabled by default.
7. Configure the overhead bytes.
• flag c2 flag-value
• flag { j0 | j1 } { sdh | sonet }
flag-value
Optional.
By default:
• The C2 overhead byte is
hexadecimal 16.
• SDH framing applies. In SDH
framing, both J0 and J1
overhead bytes are null. In
SONET framing, the J0
overhead byte is 0x01 and J1

scramble
Optional.
Scrambling is enabled by default.
11. Set the link layer protocol.
link-protocol { fr [ ietf | mfr
interface-number | nonstandard ]
| hdlc | ppp }
Optional.
The default is PPP.
The fr [ ietf | mfr interface-number
| nonstandard ] option is
supported by
HSR6802/HSR6804/HSR6808,
