Automation

Hello All,

If someone could help point me in the right direction, would be amazing.

I created a script to pull interface information for the irb interfaces that are active on our QFXs.
I tried the using a custom table and view to pull the information and produce the output similar to 
show interfaces irb terse (without the IP details)

>show interfaces irb terse
Interface                 Admin          Link     Proto              Local Remote
irb                                    up                 up
irb.x                                up                 up         inet                x.x.x.x/x
                                                                                                        x.x.x.x/x
irb.x                                up                 up         inet                x.x.x.x/x

For my test I was mainly interested in the information below.

interface description
interface name
Interface admin status
Interface oper status

On running the script, I get the following output

Interface description
irb.xxx
None
None
Interface description
irb.xxx
None
None
.
.
.
.
.

I can get the interface status from the main irb instance, but I want to get the operational and admin status information from all the sub interfaces.
There is a pre-configured table and view for the ethernet ports, but that will not work for the irbs interfaces.


Any suggestions?

Very new to scripting so I can expect I've mixed up a few things.

Thanks

Hi RoninDN,

I think the anwer that you are looking for is documented here:

Thanks,

Hi,

This was an interesting one.   So the RPC get-interface-information, doesn't actually return oper/admin status for logical interfaces.  Unlike "show interfaces terse" which does return the oper/admin status for logical interfaces.

Change your RPC  args to include terse:true and you should see data.  Also, your context within the device hierarchy  XML is .../physical-interface/logical-interface.   So you need to remove logical-interface from the following entries, else you'd be trying to get .../physical-interface/logical-interface/logical-interface... which will not work.

oper: logical-interface/oper-status
admin: logical-interface/admin-status

The following should work now.

from jnpr.junos import Device
from jnpr.junos.factory.factory_loader import FactoryLoader
import yaml

yml = """
---
IrbPortTable:
    rpc: get-interface-information
    args:

    item: physical-interface/logical-interface
    view: IrbPortView

    Irb.get()
