AV Line of Fully Managed Switches M4250 Series Main User Manual Routing concepts The switch supports IP routing. When a packet enters the switch, the switch checks the destination MAC address to determine if it matches any of the configured routing interfaces. If it does, the switch searches the host table for a matching destination IP address. If a matching entry is found, the packet is routed to the host. If no matching entry is found, the switch performs a longest prefix match on the destination IP address. If a matching entry is found, the packet is routed to the next hop. If no matching entry is found, the packet is routed to the next hop that is specified in the default route. If no default route exists, the packet is dropped. Routing table, routes and route preferences The routing table collects routes from multiple sources and list all routes: static routes, local routes, dynamically added routes, and so on. Static routes are routes that you manually add. The routing table can learn multiple routes to the same destination from multiple sources, for example dynamically added routes through routing protocols. Configure a route and display learned routes You can add or change a route in the routing table and display the automatically learned routes in the routing table. To add or change a route and display learned routes: 1. Launch a web browser. 2. In the address field of your web browser, enter the IP address of the switch. The login page displays. 3. Click the Main UI Login button. The main UI login page displays in a new tab. 4. Enter admin as the user name, enter your local device password, and click the Login button.
