Hierarchy Level [edit interfaces aex aggregated-ether-options]

Release Information Statement introduced in Junos OS Release 8.3.
Statement introduced in Junos OS Release 9.0 for EX Series switches.
Support for disable, revertive, and non-revertive statements added in Junos OS Release
9.3.
Description On the router, for aggregated Ethernet interfaces only, configure link protection. In addition
to enabling link protection, a primary and a secondary (backup) link must be configured
to specify what links egress traffic should traverse. To configure primary and secondary
links on the router, include the primary and backup statements at the [edit interfaces
ge-fpc/pic/port gigether-options 802.3ad aex] hierarchy level or the [edit interfaces
fe-fpc/pic/port fastether-options 802.3ad aex] hierarchy level.
On the switch, you can configure either Junos OS link protection for aggregated Ethernet
interfaces or the LACP standards link protection for aggregated Ethernet interfaces.
For Junos OS link protection, specify link-protection at the following hierarchy levels:
• [edit interfaces ge-fpc/pic/port ether-options 802.3ad aex]
• [edit interfaces xe-fpc/pic/port ether-options 802.3ad aex]
For LACP standards link protection, specify link-protection at the following hierarchy
levels:
• For global LACP link protection, specify at [edit chassis aggregated-devices ethernet
lacp]
• For a specific aggregated Ethernet interface, specify at [edit interfaces aeX
aggregated-ether-options lacp]
Options The statements are explained separately.
