Why does this config fail? How do I get rid of errors?  Thanks

@juniper-ptx1k# set interfaces et-0/0/58 unit 0 family inet address 192.168.10.2/32

}

}

The error indicates that Interface et-0/0/58 is a member of an AE (Aggregated Ethernet) bundle and logical unit  is not allowed on member links / physical interfaces. Please check the group configuration to check AE inteface details. 

show configuration groups

show interfaces terse | match ae

Or use "show configuration interfaces | display inheritance" ...  Ulf

Thanks for the response. What is the 'unit' in the command: set interfaces et-x/x/x unit 0 family inet address x.x.x.x/24? I didn't really have a firm grasp of what the unit is.

think subinterface or logical interface (as opposed to physical interface / port)

Hi PL2, 

I hope you are doing great!

If i am not wrong there used to be a KB for this error, but couldn't find it, anyways you can check this link which shows an AE configuration side to side.

https://www.juniper.net/documentation/en_US/junos/topics/topic-map/aggregated-ethernet-interfaces-lacp-configuring.html

In the other hand we shouldn't configure unit 0 on child interfaces of the AE, because the only configuration allow is:

Hi PL2,

You have so many group applied on this interface:

apply-groups [ FILTERS-FOR-JFLOW AE-INTERFACES-TO-SPINE INTERFACES-TO-CORE-MPE INTERFACES-TO-BFB-CORE ];

I believe one of the group is making this part of a AE bundle, probably AE-INTERFACES-TO-SPINE, once an interface is part of AE bundle you can't apply unit config to it.

In order to see the effective configuration (interface level configuration + configuration applied via groups) you can use following command:

"show configuration interface et-0/0/58 | display inheritance no-comment"

In order to confirm which group is applying which part of the config use following command:

"show configuration interface et-0/0/58 | display inheritance "

If you don't want to use the interface as part of AE bundle remove that group from interface config.

PS: Please accept my response as solution if it answers your query, kudos are appreciated too!

Thanks
