## Symptoms

- * Nexus 5K switch shuts down its port connection to Intel X710 10G adapter.
* Interface will not come up following an upgrade/reboot stating link to be down

## Cause

The firmware engine on Intel X710 10G NIC consumes LLDP traffic as it is received. When a port of Cisco 5K Switches (with LLDP enabled) is connected to a port on Intel X710 10G NIC, the port on Cisco 5K Switches will not see the necessary LLDP data from Intel X710 10G NIC. So, the Cisco 5K Switches will have its port disabled after certain time

A Support Engineer will make sure the Hotfix is compatible with your environment before providing the Hotfix.  
For faster resolution and verification, please collect [CPinfo files](http://supportcontent.checkpoint.com/solutions?id=sk92739) from the Security Management Server and Security Gateways involved in the case.

To verify the problematic card exists, check the following PCI ID:

# *lspci -vvnn \| grep -A 1 Ethernet \| grep Subsystem \| grep "1374:04b2"*

If the results above are not empty, then the problematic card indeed exists in the enviornment.

To resolve, disable the LLDP packets in the NIC. To do so, run the following command:

*# ethtool -set-priv-flags \<interface-name\> disable-fw-lldp on*
