NOTE: You can disable the sending of link event TLVs.
To disable the sending of link event TLVs:
[edit protocols oam ethernet link-fault-management]
user@switch# set interface interface-name negotiation-options no-allow-link-events
Create an action profile to define event fault flags and thresholds to be taken when
6.
the link fault event occurs. Then apply the action profile to one or more interfaces.
(You can also apply multiple action profiles to a single interface.)
Name the action profile:
a.
[edit protocols oam ethernet link-fault-management]
user@switch# set action-profile profile-name
Specify actions to be taken by the system when the link fault event occurs:
b.
[edit protocols oam ethernet link-fault-management]
user@switch# set action-profile profile-name action syslog
user@switch# set action-profile profile-name action link-down
Specify events for the action profile:
c.
[edit protocols oam ethernet link-fault-management]
user@switch# set action-profile profile-name event link-adjacency-loss
NOTE: For each action profile, you must specify at least one link event
and one action. The actions are taken only when all of the events in the
action profile are true. If more than one action is specified, all actions are
executed. You can set a low threshold for a specific action such as logging
the error and set a high threshold for another action such as system logging.
Set a remote interface into loopback mode so that all frames except OAM PDUs are
7.
looped back without any changes made to the frames. Set the remote DTE in loopback
mode (the remote DTE must support remote-loopback mode) and then enable remote
loopback support for the local interface.
[edit protocols oam ethernet link-fault-management]
user@switch# set interface interface-name remote-loopback
user@switch# set interface interface-name negotiation-options allow-remote-loopback
