Context
Do as follows on the device that needs the association.
Procedure
Step 1
Run:
system-view
The system view is displayed.
Step 2
Run:
oam-mgr
The OAM management view is displayed.
Step 3 Configure unidirectional or bidirectional transmission of fault information between Ethernet
CFM and an interface. Choose a configuration scheme according to
Table 4-2 .
Table 4-2 Configuration schemes for Ethernet CFM and interface association
Scenario Configuration Scheme 1 Configuration Scheme 2
Fault
information
needs to be
transmitted
bidirectional
ly between
Ethernet
CFM and an
interface. Choose either of the following
commands (the two commands have
the same function):
l If you prefer to specify the MD
and MA before the interface, use
the following command:
oam-bind cfm md ma trigger if-
down interface
l If you prefer to specify the
interface before the MD and MA,
use the following command:
oam-bind interface cfm md ma
trigger if-down
NOTE
After configuring bidirectional
transmission of fault information, run the
display current-configuration
command to check the configuration.
The command output displays the oam-
bind ingress cfm md ma egress interface
and
oam-bind ingress interface egress
cfm md ma trigger if-down commands,
but does not display the oam-bind cfm
md ma trigger if-down interface or
oam-bind interface cfm md ma trigger
if-down
command. The displayed
commands configure reverse
transmission directions of fault
information.
Run the following commands at a
random order (each command
configures fault information
transmission in a single direction):
l oam-bind ingress cfm md ma
egress interface
When Ethernet CFM detects a
fault, the physical status of the
interface associated with Ethernet
CFM becomes Down.
l oam-bind ingress interface egress
cfm md ma trigger if-down
When an interface associated with
Ethernet CFM goes Down, the
OAM management module sends
fault information to the associated
Ethernet CFM function, and then
Ethernet CFM sends the fault
message to the remote device.
