Study Notes

Cisco IOS Access Methods

Console access is most appropriate for initial configuration in the equipment room.
Console access is also recommended if using a special cable provided by a manager for configuring a switch.
Telnet/SSH is the most appropriate method for in-band access to IOS over a network connection.
Auxiliary access is used when accessing a router remotely via phone.

Basic Device Configuration

Command to name a switch "Sw-Floor-2": hostname Sw-Floor-2.
Secure privileged EXEC mode access with the command: enable secret class.
Enable password authentication for user EXEC mode using: login.
Encrypt all plaintext passwords using: service password-encryption.
Configure a banner for switch connections with: banner motd $ Keep out $.

Ports and Addresses

IPv4 addresses are structured in Dotted-decimal format.
Represented by four decimal numbers, each between 0 and 255, separated by periods.
Switch Virtual Interface (SVI) type has no physical port associated.

Privileged EXEC mode provides access to all commands and features.
Switch(config)# prompt indicates global configuration mode.
Switch> prompt indicates user EXEC mode.
Commands to return to privileged EXEC prompt: CTRL+Z or end.

Memory Locations

RAM loses all content when the device is restarted.
The startup configuration file is stored in NVRAM.
Running configuration affects the device operation immediately upon modification.

User EXEC Mode

User EXEC mode prompt ends with a “>” symbol.
Limited aspects of the router’s configuration can be viewed in user EXEC mode.
