Flex links is a network switch feature in Cisco equipment which enables redundancy and load balancing at the layer 2 level. The feature serves as an alternative to Spanning Tree Protocol or link aggregation. [citation needed] A pair of layer 2 interfaces, such as switch ports or port channels, has one interface configured as a backup to the ...
Typically, this includes routers, switches, access points, network interface cards and other related hardware. This is a list of notable vendors who produce network hardware. This is a list of notable vendors who produce network hardware.
Once the switches have been assigned a bridge ID and the protocol has chosen the root bridge switch, the best path to the root bridge is calculated based on port cost, path cost and port priority. [6]: 506 Ultimately STP calculates the path cost on the basis of the bandwidth of a link, however links between switches may have the same bandwidth ...
"Corporate market" refers to enterprise networking and service providers. Enterprise networks Products in this category are Cisco's range of routers, switches, wireless systems, security systems, WAN acceleration hardware, energy and building management systems and media aware network equipment.
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."
Cisco Inter-Switch Link (ISL) is a Cisco proprietary link layer protocol that maintains VLAN information in Ethernet frames as traffic flows between switches and routers, or switches and switches. [1] ISL is Cisco's VLAN encapsulation protocol and is supported only on some Cisco equipment over the Fast and Gigabit Ethernet links. It is offered ...
