IOS XRv 9000 Gigabit Ethernet Interfaces missing

Good day,

 

I have installed IOS XRv 9000 from an OVA downloaded from the Cisco site.

I have tried many different versions and all of them do not have any interfaces except for Mg0 after booting. 

I am importing the OVA into ESX.

 

Any help would be appreciated.

Current version: Cisco IOS XR Software, Version 6.2.25

Kind Regards,

Hendrik

Hi Hendrick,

 

Have you provisioned other nics through ESX? You might have placed only one nic, and that's why you only see one interface.

I'm encountering this exact same issue with 6.2.25. I've tried ESXi and QEMU/KVM with the same result. Dropping into shell and running ifconfig -a shows only eth0 and the bridge mappings for the control plane regardless of how many NICs are configured.

Hey bersoare,

Thanks for the prompt response.

I've tried E1000, VMXNET3, and virtio-pci ,  all of which are properly detected on a hardware level.
Here's what I'm seeing (I have four nics configured in the below example to keep the output short, I've tested with up to 12 configured):

Thanks for taking a look at this. I've got some time free today and tomorrow, so if there's any further information you require, I'd be happy to provide it.

 

 

 

 

 

 

 

 

 

 

 

Hi Jake,

 

In XRv, your eth0 will be mapped to the mgmt int, eth1 and 2 correspond to interfaces used for internal communication: 

 

[    2.878159] udevd[1073]: renamed network interface eth1 to ctrl-eth0
[    2.891215] udevd[1083]: renamed network interface eth2 to host-eth0

 

I don't see the other interfaces (that would be eth3, eth4, and so on). 

Check this page for reference:

 

https://www.cisco.com/c/en/us/td/docs/routers/virtual-routers/configuration/guide/b-xrv9k-cg/b-xrv9k-cg_chapter_01000.html#concept_921C07E3903E4A47A30E8504C6E81AA5

 

It really looks like something is not right at the drivers/kernel level.

 

I would try going for a clean install from the ISO, or maybe redeploying it on another hypervisor (KVM, for example) just for comparison.

 

 

That was my original thought as well. The info provided above was for KVM. I've also gotten the same behavior on ESXi 6.0U2 as the OP. I've tried the OVA, the qcow2 image, and the iso files provided in the download with the same result on each.

I'm running into a similar issue with this version.  If I go over 22 interfaces (0 - 21)  I lose all gigabit ethernet interfaces.  22 and under, everything works fine. I have tried with various combinations of pci-bridges but nothing seems to change.  The guest machine shows all interfaces with lspci. I am using an up to date version of qemu and creating the device with libvirt/virsh

Any luck?

None yet.  I'll take another shot at this next week.

I had the same problem.

The interfaces where not visible in any show interface cmd,

it was enough to enter in configuration mode and no shut them.

 

Can you please try to enter int conf mode and issue:
interface ?
it should give you as outout the GIgabitEthernet0/0/0/0

 

important is to assign to the XRv at least 7 interfaces

Has anyone found a solution for this yet?  I've tried everything but am unable to get a physical interface on IOS-XRv.

The device will support some interfaces but not all. The state of what I have been able to do with kvm is still 22 interfaces, as mentioned in my previous post.  Although, I haven't tried much since my last post as I am not actively using the XRv.

Hi all,

Anyone got a solution on this issue ?

Thanks

Hi Ju,

I ended up resolving this issue by moving the VM to a Xeon CPU based host. I only see this issue on an AMD CPU based host.

What CPU does your host have?
