Cisco routers are Level 3 devices and can do IP routing but not Layer 2 switching, so they support the show ip route command but not the show mac address-table command. For example, Cisco Layer 2 switches support the show mac address-table command but not the show ip route command, because that command lists IP routes at Level 3.

However, a couple of things do work differently with routers than switches, such as the configuration of IP addresses and the CLI, because switches and routers do different things. The startup config (in NVRAM), running config (in RAM), and external servers (like TFTP), along with using the copy command to copy the configuration files and Cisco IOS images.Using the debug command to create log messages about certain events, so that any user can monitor those messages using the terminal monitor command.Configuring Ethernet interfaces using the speed and duplex commands.Navigating through different configuration mode contexts using commands like line console 0 and interface.Configuring an interface to be administratively disabled ( shutdown) or enabled ( no shutdown).Configuring the SSH encryption keys and login credentials.Configuring the hostname and interface description.Configuring the console and Telnet and enabling secret passwords.Setup mode, which guides the user through a set of questions to create a simple initial configuration.CLI help, command editing, and command recall features.Enter or exit configuration mode using the configure terminal, end and exit commands, and the Ctrl+Z key sequence.Here some other actions that are the same across devices:

For example, show, vty and enable password all work the same on both routers and switches. But these commands are not unique to routers many Cisco routers and switches use the exact same commands. Routers support a relatively large number of IOS commands my quick check found around 5,000 Command Line Interface (CLI) commands. Routers play a key role in enterprise networks because they connect the organizationвЂ™s devices to the internet.
