X710 DCBX with Juniper EX4500

Hello all,

We have newly installed Intel X710 NICs on Windows Server 2012 R2 connecting to a Juniper EX4500 with DCBX enabled. The Juniper DCBX information for the interfaces show enabled and everything looks good. The data center tab on the X710 shows the following:

Status: Non Operational

DCBx Version: IEEE 802.1Qaz

Priority Group: Operational

Priority Flow Control: Operational

iSCSI Status: Feature not present in peer TLV

Our other NICs we have are X520 and they show DCBX to be operational. All interface settings on the Juniper are identical.

To my knowledge the X710 devices have the latest drivers installed.

Has anyone seen something like this before or have any ideas?

I've read a few links that stated LLDP was turned off somehow on the X710 cards. It states how to turn it back on for Linux systems but I don't see anything regarding Windows. I've pretty much run out of ideas on this.

Hi Knightmese, we'd like to confirm if the X520 were also connected to the same Juniper EX4500. Thanks.

They are. The EX4500 are running 12.3R12.4.

Thanks Knightmese, kindly help to provide the additional information below for us to further investigate the issue.

 

 

1. Output of the following commands in your win2k12 system with X710 installed.

 

get-netqosdcbxsetting

 

get-netqostrafficclass

 

get-netqosflowcontrol

 

get-netqospolicy

 

get-netadapterqos

 

 

2. Logs in Juniper switch showing the DCB status of connected port.

In a nutshell it was because a native VLAN wasn't set on the Juniper ports connected to the X710 adapters which use different VLANs that only allow tagged traffic. LLDP packets on Juniper devices are untagged so you have to specify a native VLAN to received these packets. If you don't they just get dropped. Once we configured a native VLAN, DCBX came right up.

The X520 adapters didn't have this problem because they did not use tagged VLANs. We were migrating to a new storage system.

Regardless I appreciate the responses, Vince. Thank you. I hope this helps out if anyone else runs into this issue.
