15. What are the unique qualities that differentiate the M4300 from other market alternatives? Mixed stacking between 1G models and 10G models - using 10G ports - is an important differentiator: only high-end series with costly and complex stacking kits are available in the market as of today. This brings even more simplicity for edge to core topologies, and greater performance with spine and leaf stacking topologies. Nonstop forwarding architecture and hitless failover are key for high availability in a stack: when the management unit fails, most competitive "redundant" solutions block the traffic across the stack during the failover. This can take 10, 20, 30 seconds - even longer sometimes - and clients connected to all other switches in the stack go totally offline. Distributed uplinks to the core are also down. M4300 offers real high availability instead: Nonstop Forwarding (NSF) enables the stack to secure forwarding end-user traffic on all other switches when the management unit fails. And when both the management unit and the backup unit connect to the core using distributed link aggregation (LACP), there is no possible service interruption while the backup management unit takes over. M4300 1G models additional advantages are: •Dual, redundant modular power supplies for cost-effective power redundancy • More PoE budget than most competitive solutions, up to PoE+ full provisioning •Full Layer 3 feature set including Policy-based routing and OSPF with zero licensing charges M4300 10G models additional advantages are: •Half-width models with low acoustics for active-active server and storage connections across two switches in 1U and redundant topof-rack •Hybrid 10G copper and 10G fiber port counts because 10 Gigabit Ethernet itself is hybrid: many server and storage equipment come with SFP+ fiber or DAC cables for low latency reasons, while 10G copper is increasingly more widely available. •Full Layer 3 feature set including Policy-based routing and OSPF with zero licensing charges 16.

M4300 support SDN and OpenFlow 1.3. What is supported? M4300 OpenFlow feature enables the switch to be managed by a centralized OpenFlow Controller using the OpenFlow protocol. •Support of a single-table OpenFlow 1.3 data forwarding path • The OpenFlow feature can be administratively enabled and disabled at any time • The administrator can allow the switch to automatically assign an IP address to the OpenFlow feature or to specifically select which address should be used •The administrator can also direct the OpenFlow feature to always use the service port (out-of-band management port) • The Controller IP addresses are specified manually through the switch user interface •The list of OpenFlow Controllers and the controller connection options are stored in the Controller Table •The OpenFlow component in M4300 software uses this information to set up and maintain SSL connections with the OpenFlow Controllers •M4300 implements a subset of the OpenFlow 1.0.0 protocol and a subset of the OpenFlow 1.3 • It also implements enhancements to the OpenFlow protocol to optimize it for the Data Center environment and to make it compatible with Open vSwitch (OVS 2.3.0)
