CGN interface ServiceApp down

peter.ivanov · ‎09-24-2015

Good Day!

Should the versions of ASR9K IOS XR and VSM module be the same? For my case I have IOS XR 5.3.1 and VSM module 5.3.2. Problem is that Interface ServiceApp is DOWN state.

Hi Peter,

we don't enforce the use of same version of the XR image and .ova image, but we strongly recommend it.

In this particular case, I don't think ServiceApp is down because of different versions of XR and .ova.

If all the TenGig ports are up/up, please check whether the service-location config is missing under cgn instance.

hth,

Aleksandar

Hi Aleksandar,

I have just checked cgn instance config and it is looks right.

Hi Aleksandar,

Thanks for your response. Just for information. Changing the version of .ova file to the same version of IOS XR resolve the problem.
