Layer 3 switch cannot connect to the network

Verify Layer 3 interface IP configuration: If the switch acts as the gateway for inter-VLAN routing (Layer 3 switch), use ' show ip interface brief ' to check that each VLAN interface (SVI) has the correct IP address and subnet mask, and that the interface status is “up/up. I am using the schools internet connection to supply the switch/hosts with the connection. I am able to ping to other devices on the VLAN, and I am able to ping. In this lesson, we examine the network devices that operate at Layer 3 of the OSI model. Why do we need a network router?I have a lab with different networks and on one network I have a layer 2 and layer 3 switch, the layer 3 switch is directly connected to a router. By understanding and resolving these issues, you can maintain a resilient network infrastructure. If the entire switch is unresponsive, or.
