When you run tmsh show net interface on a Virtual Edition/Z100 BIG-Ip device, you see "Media None".


External Link status cannot readily be determined from within the VE using usual interface status commands


This occurs on devices that are not using SR-IOV


check the link state on the hypervisor or connected devices check the results of higher layer protocols (ARP, ping, etc.)
