Description
For Ethernet interfaces on M7i and M10i routers with Enhanced CFEB (CFEB-E), and on M120, M320, MX Series, and T Series routers, specify connectivity fault management for IEEE 802.1ag Operation, Administration, and Management (OAM) support.In Junos OS Release 9.3 and later, this statement is also supported on aggregated Ethernet interfaces.
The remaining statements are explained separately. See CLI Explorer.
Options
Asynchronous-notification—Generate asynchronous-notification (Laser off for optical physical) option is
introduced in Junos OS release 20.4R1 for ACX and MX.
Required Privilege Level
interface—To view this statement in the configuration.
interface-control—To add this statement to the configuration.
Release Information
Statement introduced in Junos OS Release 8.4.
