2.
Configure remote loopback on CE1 to test the connectivity and performance of the link
between CE1 and CE4 before the link is used to transmit services.
3.
Configure link monitoring on CE1 to monitor the performance and quality of the link
between CE1 and CE4.
4.
Configure association between EFM and interfaces on CE1 so that when the link between
CE1 and CE4 goes faulty, traffic sent from CE3 will not be sent along the link.
Data Preparation
To complete the configuration, you need the following data:
l
Period of detecting symbol errors and threshold for the number of symbol errors detected
in the period on GE 1/0/2 of CE1
l
Period of detecting errored frames and threshold for the number of errored frames detected
in the period on GE 1/0/2 of CE1
l
Period of detecting errored frame seconds and threshold for the number of errored frame
seconds detected in the period on GE 1/0/2 of CE1
Procedure
Step 1
Configure basic EFM functions.
# Enable EFM on CE1.
<HUAWEI>
system-view
[HUAWEI]
sysname
CE1
[CE1]
efm enable
# Enable EFM on CE4.
<HUAWEI>
system-view
[HUAWEI]
sysname
CE4
[CE4]
efm enable
# Configure the EFM mode to passive on GE 2/0/1 of CE4.
[CE4]
interface gigabitethernet 2/0/1
[CE4-GigabitEthernet2/0/1]
efm mode passive
# Enable EFM on GE 2/0/1 of CE4.
[CE4-GigabitEthernet2/0/1]
efm enable
[CE4-GigabitEthernet2/0/1]
quit
# Enable EFM on GE 1/0/2 of CE1.
[CE1]
interface gigabitethernet 1/0/2
[CE1-GigabitEthernet1/0/2]
efm enable
[CE1-GigabitEthernet1/0/2]
quit
# Verify the configuration.
If EFM is correctly configured on CE1 and CE4, GE 1/0/2 and GE 2/0/1 will enter the handshake
phase. Run the
display efm session
{
all

interface
interface-type
interface-num
} command
on CE1 or CE4. The command output shows that the EFM state is
detect
on GE 1/0/2 or GE
2/0/1.
