Release Information

Statement introduced in JUNOS Release 9.4 for EX Series switches.

Description

Specify the discovery mode used for IEEE 802.3ah Operation, Administration, and Maintenance (OAM) link fault management (LFM) support. The discovery process is triggered automatically when OAM 802.3ah functionality is enabled on an interface. Link monitoring is done when the interface sends periodic OAM PDUs.

Options

active—In active mode, the interface discovers and monitors the peer on the link if the peer also supports IEEE 802.3ah OAM functionality.

passive—In passive mode, the peer initiates the discovery process.

Once the discovery process is initiated, both sides participate in discovery.

Required Privilege Level
