Remarks
Optional.
By default, the description of a
POS interface is interface name
Interface, for example, POS1/2/0
Interface.
Optional.
The default is slave.
Optional.
The default is 32 bits.
Optional.
Loopback is disabled by default.
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
overhead byte is null.
Optional.
By default, CRC is performed for
the J1 byte.
Optional.
The default is SDH.
Optional.
Scrambling is enabled by default.
Optional.
The default is PPP.
The fr [ ietf | mfr interface-number
| nonstandard ] option is
supported by
HSR6802/HSR6804/HSR6808,
but is not supported by FIP-600.
Optional.
The MTU is in the range of 128 to
2000 and defaults to 1500.
