This article provides instructions on how to configure IPv4 static routes on the switch through the Command Line Interface (CLI).Static routing refers to the configuration of the path selection of routers. This type of mechanism takes place in the absence of communication between routers regarding the current topology of the network and thus, manually configuring routes to the routes table on the switch is recommended. Static routes help reduce the overhead on the switch CPU. You cannot configure a static route through a directly‑connected IP subnet where the device gets its IP address from a DHCP server. To configure a static IPv4 interface on the switch, click herefor instructions. Step 1. Log in to the switch console. The default username and password is cisco/cisco. If you have configured a new username or password,.
