When the IEEE 802.3ah OAM protocol is enabled on a physical interface, the discovery
process is automatically triggered. The discovery process permits Ethernet interfaces to
discover and monitor the peer on the link if it also supports the IEEE 802.3ah standard.
You can specify the discovery mode used for IEEE 802.3ah OAM support. The discovery
process is triggered automatically when OAM IEEE 802.3ah functionality is enabled on
a port. Link monitoring is done when the interface sends periodic OAM PDUs.
To configure the discovery mode, include the
oam ethernet link-fault-management interface interface-name]
[edit protocol oam ethernet link-fault-management interface interface-name]
link-discovery (active | passive);
In active mode, the interface discovers and monitors the peer on the link if the peer also
supports IEEE 802.3ah OAM functionality. In passive mode, the peer initiates the discovery
process. After the discovery process has been initiated, both sides participate in discovery.
