WebThe data link layer or layer 2 is the second layer of the seven-layer OSI model of computer networking. This layer is the protocol layer that transfers data between adjacent network nodes in a wide area network (WAN) or between nodes on the same local area network (LAN) segment. [1] The data link layer provides the functional and procedural ... WebEX Series switches provide Layer 2 loop prevention through Spanning Tree Protocol (STP), Rapid Spanning Tree protocol (RSTP), and Multiple Spanning Tree Protocol (MSTP). Loop protection increases the efficiency of STP, RSTP, and MSTP by preventing interfaces from moving into a forwarding state that would result in a loop opening up in the network.

WebSTP was developed specifically as a loop prevention mechanism for Layer 2 Ethernet. Layer 2 Loops. Without STP enabled, Layer 2 loops can form, causing broadcast, multicast and … Web14 Mar 2024 · Cisco's cloud-based Meraki firewalls are a great example of this. 2. WAN optimization and SD-WAN. Another common spot for network bottlenecks is a company's wide area network (WAN). Because the WAN often leverages leased lines from service providers, it's impossible to simply increase throughput without incurring significant costs. WebIf you have a layer-2 loop topology, make certain that the alternative path can reach the FortiGate unit and that STP is enabled on the FortiLink layer-3 trunk. If you have two FortiSwitch units separately connected to two different intermediary routers or switches, the uplink interfaces for both FortiSwitch units must have fortilink-l3-mode enabled. coinbase link bank
