Founded in 2004 by former Cisco engineers, Arista has emerged as a rival to Cisco in the multibillion-dollar market for ethernet switches used in data centers. Arista to pay $400 million to Cisco ...
NetFlow is a feature that was introduced on Cisco routers around 1996 that provides the ability to collect IP network traffic as it enters or exits an interface. By analyzing the data provided by NetFlow, a network administrator can determine things such as the source and destination traffic, class of service, and the causes of congestion.
A LAG is a method of inverse multiplexing over multiple Ethernet links, thereby increasing bandwidth and providing redundancy. It is defined by the IEEE 802.1AX-2008 standard, which states, "Link Aggregation allows one or more links to be aggregated together to form a Link Aggregation Group, such that a MAC client can treat the Link Aggregation Group as if it were a single link."
Controllers should listen on TCP port 6653 for switches that want to set up a connection. Earlier versions of the OpenFlow protocol unofficially used port 6633. [2] [3] Some network control plane implementations use the protocol to manage the network forwarding elements. [4] OpenFlow is mainly used between the switch and controller on a secure ...
