If member interfaces are added to ae bundle and ae bundle is not created on the router, interface descriptions are not displayed on the member link of the ae bundle.
If a user configures an ethernet (et) interface and links it to an aggregated ethernet (AE) interface without the required complete AE configuration, then system identifies this as an incomplete configuration. This configuration is deferred until user applies the required full configurations. E.g. set interfaces et-0/0/1 description et-ingress-traffic set interfaces et-0/0/1 ether-options 802.3ad ae0 Incomplete Configuration: -------------------------------- -The et interface is mapped to ae0 -However, the AE interface (ae0) itself is not fully configured Result: -------- -Configuration is treated as incomplete -It is not applied -It (e.g. description) will not appear in "show interfaces" CLIs output Complete Configuration ---------------------------- When the required AE-related configurations is fully applied then it visible in operational outputs. E.g. set interfaces et-0/0/1 description et-ingress-traffic set interfaces et-0/0/2 description et-egress-traffic set chassis aggregated-devices ethernet device-count 10 set interfaces et-0/0/1 ether-options 802.3ad ae0 set interfaces et-0/0/2 ether-options 802.3ad ae0 set interfaces ae0 aggregated-ether-options minimum-links 1 set interfaces ae0 unit 0 family inet address 10.1.1.1/24 Result -------- -The configuration is considered complete and valid -Successfully applied to the system -All attributes are visible in show command outputs Summary ----------- -Partial AE configurations are not applied immediately -The system waits until all required configurations are present -Only complete configurations are activated and reflected in operational outputs Recommendation: ---------------------- Customers are advised to: -Ensure all dependent AE configurations are fully defined before expecting them to take effect -Note that operational outputs will reflect the expected state only after the complete configuration is applied
