Data Traffic Interfaces
As shown in the above figure, the appliance has 4 physical 10G ports --- 10GB1/2/3/4 those are configured in SR-IOV mode. Each port is partitioned into 32 SR-IOV Virtual Functions to provide a total of 128 virtual interfaces for CloudEOS and vEOS instances on the appliance. You may optionally configure a VLAN to be used for each virtual interface. The VLAN configuration allows separation of broadcast domain for traffic in and out of each physical port. The VLAN tag handling is done by SRIOV NIC and it is transparent to the CloudEOS and vEOS Router. Please note that for performance reasons, the CloudEOS and vEOS launcher script creates CloudEOS and vEOS Router with all of its CPU cores and memory from the same NUMA node. Therefore, all required CPU resources for a CloudEOS and vEOS Router need to be available on one socket. If required, resources for launching a new CloudEOS and vEOS Router are split across two sockets, CloudEOS and vEOS launcher will not be able to launch the CloudEOS and vEOS Router. In such scenario, user may need to reconfigure the existing VMs and/or reduce resource requirements of the new VM to fit within a NUMA node.
