A99-4HG : tengig ports doesn't show up

[allalamine]

Hello,

I'm trying to connect a A99-4HG-FLEX line card to ASR9910.

Only four 100G ports are available, anyone knows how to enable the remaining 40 tengig ports ?

Here are the possible port combinations:

To enable the 10ge ports they need to be configured like in this example:

Thank you Sam,

Does it support oversubscription ? can we use all ports even if it is limited to 400G ?

It says "Oversubscription will be supported on these line cards in a future release of IOS XR 6.2.x train.", but in the second link, port configurations shown don't seem to support it.

BR,

Apologies I should not have used the second link, while it shows how to carve out the interfaces it is more applicable to the 10ge/1ge cards, oversubscription on this card is not possible. You can use this command to find the possible port combinations "show controller np valid-port-groups all". The layout of the card is like in the attached image.

Clear, many thanks Sam
