4 Configuring Ethernet Services
In this example, the EFS4 board is used. This
parameter adopts the default value GFP.
Mapping Protocol of the VCTRUNKs on
the Ethernet boards of the interconnected
equipment at both ends must be set to the
same value.
In this example, this parameter adopts the
default value Scrambling mode [X43+1].
Scramble of the VCTRUNKs on the
Ethernet boards of the interconnected
equipment at both ends must be set to the
same value.
In this example, this parameter adopts the
default value FCS32. Check Field Length
of the VCTRUNKs on the Ethernet boards of
the interconnected equipment at both ends
must be set to the same value.
When Mapping Protocol is set to GFP, FCS
Calculated Bit Sequence is set to Big
endian. FCS Calculated Bit Sequence of
the VCTRUNKs on the Ethernet boards of
the interconnected equipment at both ends
must be set to the same value.
When Mapping Protocol is set to GFP, this
parameter is valid and adopts the default
value -. Set Inverse Value for CRC of the
VCTRUNKs on the Ethernet boards of the
interconnected equipment at both ends must
be set to the same value.
In this example, Enabling LCAS is set to
Enabled.
In this example, this parameter adopts the
default value Huawei Mode. If the
interconnected equipment at both ends is
Huawei equipment, LCAS Mode is set to
Huawei Mode for the interconnected
equipment.
