A network switch, configured for performing layer 2 and layer 3 switching in an Ethernet (IEEE 802.3) network without blocking of incoming data packets, includes a switching module for performing layer 2 and layer 3 (specifically Internet Protocol) switching operations, and a plurality of network ...
This deteriorates Layer 3 convergence performance of IP traffic. If the switch is enabled to perform Layer 2 forwarding for IP traffic during the switchover, the convergence performance can be improved. By default, the switch is enabled to perform Layer 2 forwarding for IP traffic during a ...
3.2.2Network layer The network layer relies on the Internet technology as a main communication for connecting IP-based smart devices. The main role of this layer isinterconnectivityallowingIoTinformation to be shared and aggregated byinformation systems. Operations offered byIoT devicesmay be located a...
Moreover, this type of switch operates at both layer 2 and layer 3 of the OSI model, facilitating seamless communication between networks. There is a great deal of confusion surrounding the use of layer 3 switches because, in a traditional setup, routers operate at layer 3 of the OSI model...
The interface is switched to Layer 3 mode. By default, an Ethernet interface works in Layer 2 mode. Run ospf network-type p2mp A network type is configured for the OSPF interface. A P2MP network must be forcibly changed from another network type. For details, see Configuring Network Types...
A Layer 3 switch can perform IP routing tasks as well as Layer 2 tasks such as VLANs. Moreover, a Layer 3 switch can typically route faster than a router, improving network performance. Futher, since the Layer 3 switch can route between VLANs, you can use a basic router that doesn’...

This prevents the impact of the loop on the Switch and uplink network. Configure interfaces on other switching interfaces as trunk or hybrid interfaces and configure these interfaces to allow packets from VLANs to pass through to ensure Layer 2 connectivity on the new branch network and between ...
If an Ethernet interface already has Layer 2 configuration, this command fails to be executed on the interface. Before running this command on the interface, delete all the Layer 2 configuration of the interface. If many Ethernet interfaces need to be switched to Layer 3 mode, run the und...
