Fixed In:

Opened: Jun 16, 2021

Severity: 4-Minor


The ordering of NICs 5-10 in VMware ESXi is based on PCI coordinates for the first boot and the order is ensured based on the /etc/ethmap script written by the kernel during initialization. BIG-IP VE does not follow/maintain the NIC order defined in the VMware ESXi hypervisor.


When using 5-10 NICs in VMware ESXi and NSXT platforms, automation is prohibited due to BIG-IP VE not maintaining the NIC order defined in the hypervisor.


Using 5-10 interfaces, swap/remove/add an interface at the hypervisor level.



Fix Information

Enabled BIG-IP VE scripts to honor the NIC order defined by the user in the VMware ESXi hypervisor and NSXT platforms.
