Typical WiFi networks utilize a single, central Wireless LAN Controller (WLC) to act as a gateway between the wireless APs and the wired network. Arista differentiates itself by allowing the wireless network to utilize a distributed set of aggregation switches to connect APs to the wired network. This feature allows a decentralized and distributed set of aggregation switches to bridge wireless traffic on behalf of the set of APs configured to VXLAN tunnel all traffic to those aggregation switches, or their “local” APs.

Arista campus switches allow extensive and fine grained hardware based flow tracking and management features. They

Enabling “Proxy ARP/ND for Single Aggregation (AG) VTEP Campus Deployments without EVPN” allows an aggregation VTEP to proxy reply to a VXLAN-encapsulated ARP request/NS when the ARP/NS target host is remote and the ARP/ND binding is already learned by the AG VTEP.

The CCS-750X-48ZXP is a 48 port 10GBASE-T linecard, capable of several full-duplex link speeds to support connecting to a variety of compatible devices of varying capabilities. All supported linkup speeds on this card can be automatically selected during the linkup process using IEEE 802.3 Clause 28 auto-negotiation. Note that IEEE 802.3 also allows for speeds lower than 1Gbps to link up without clause 28 auto-negotiation.
