Value in This Example Description
Set
Inverse
Value
for CRC
VCTRUNK1: -
VCTRUNK2: -
VCTRUNK3: -
VCTRUNK4: -
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.

Parame
ter
Value in This Example Description
Enablin
g LCAS
VCTRUNK1: Enabled
VCTRUNK2: Enabled
In this example,
Enabling LCAS
is set to
Enabled
.
LCAS
Mode
VCTRUNK1: Huawei
Mode
VCTRUNK2: Huawei
Mode
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.
Hold-
off Time
(ms)
VCTRUNK1: 2000
VCTRUNK2: 2000
In this example, this parameter adopts the
default value
2000
. You can set this
parameter according to the expected hold off
time of LCAS switching.
WTR
Time(s)
VCTRUNK1: 300
VCTRUNK2: 300
In this example, this parameter adopts the
default value
300
. You can set this parameter
according to the expected WTR duration of
LCAS recovery.
TSD
VCTRUNK1: Disabled
VCTRUNK2: Disabled
In this example,
TSD
is set to
Disabled
. In
this case, the LCAS protocol does not
monitor the status of the B3 or BIP bit errors
of a VCTRUNK member.
Min.

n
VCTRUNK1: 256
VCTRUNK2: 256
Sets the min. members - transmit direction.
When the LCAS is enabled and the number
of available members is smaller than this
value, an alarm is reported.
