Back Panel Ethernet Connections

On the back panel of the Arista CloudEOS and vEOS Router Appliance, locate the Ethernet Integrated 10/100/1000 Mbps NIC connectors. The appliance has four physical 1G ports --- NIC1/2/3/4. NIC1 and NIC2 are aggregated to a bounded interface device0 in 802.3ad mode. So they need to be connected to a network device supporting LACP.

The appliance has four 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. Each CloudEOS and vEOS instance can be assigned up to four virtual functions/interfaces. 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.
