You must have secret password access to make any changes via a telnet session or through the console port. Before you do anything you need to determine if you want to change the speed for a single port (ports on a 2924XL are configured as interfaces), or all ports in a particular VLAN? By default all interfaces are allocated to VLAN1.<br><br>It is extremely important to find out what your current configuration is before making any changes. For your assistance, here are the commands to view your configuration, and to change the speed for a partucular interface. Remember, if you don't know what to do after entering a command, enter a space and a question mark then hit the enter key. This will give you a list of commands needed to complete the sequence.<br><br>From the enable mode type in: sh config <cr><br>This shows your switches current configuration.<br><br>From the enable mode type in: config t <cr><br>This takes you into configuration mode.<br><br>From the config mode type in: interface FastEthernet 0/x <cr><br>x is the port/interface you want to change the speed on.<br>This takes you to (config-if) mode.
