switches like the G8000 or G8052 which support forty-eight 1 GbE ports to the servers and four 10 GbE uplinks. In

either scenario, the G8264 provides exceptional value by providing the following support:

Up to 12 G8000/G8052 switches (576 servers) when using the four 10 Gb uplinks per G8000/G8052, while

still having the four 40 Gb uplinks from the G8264 to the core

Up to 16 G8000/G8052 switches (768 servers) when using the four 10 Gb uplinks per G8000/G8052 and

using 10 Gb SFP+ break-out cables in the four 40 Gb ports with no uplinks to a core

Keep in mind the following additional details:

Logical configuration: Configure G8000/G8052 for Layer 2 and apply static routes for L3 forwarding

Full Layer 2/3 Feature Set: STP, MSTP, RSTP, PVRST+; RIP v1/2, static routes, OSPF

Security: 802.1X; RADIUS/TACACS+; Wire Speed ACLs, SSH v1, v2; HTTPS Secure BBI

QoS: Up to eight queues per port, IEEE 802.1p and DiffServ prioritization

The following high-level configuration is an example of how a configuration might look if the G8052 is used as leaf

switches and the G8264 is used as a spine switch.
