Switch and switch to router Table 1. Equipment and hardware required for this lab. Gather the necessary equipment and cables. To configure the lab, make sure the equipment listed in Table 1 is available. Common configuration tasks include setting the hostname, access passwords, and MOTD banner. Interface configuration is extremely important. In addition to assigning a Layer 3 IP address, enter a description that describes the destination connection speeds troubleshooting time.

Configuration changes are effective immediately. Configuration changes must be saved in NVRAM to be persistent across reboot. Configuration changes may also be saved off-line in a text file for auditing or device replacement. Cisco IOS switch configuration is similar to Cisco IOS router configuration. Scenario In this lab students will configure common settings on a Cisco Router and Cisco Switch. Given an IP address of 198.133.219.0/24, with 4 bits borrowed for subnets, fill in the following information in the table below. (Hint: fill in the subnet number, then the host address.
