Run privileged commands within global config mode

Beginning with the IOS 12.3, privileged-exec mode commands (such as show running-configuration, show interface status, etc.) can be executed within the global configuration mode and its submodes. This allows you to execute privileged-exec mode commands without needing to exit the current configuration mode. Here is an example that explains the usefulness of this feature:

ios command not found

In the example above you can see that we’re currently in the interface mode. We want to get more information about the interface with the show interface Fa0/1 command, but we got an error because the command is not available in this mode. However, if we use the do keyword in front of the command, the command will succeed:

do command

The command was now executed because of the do keyword. Notice that we’re still in the interface submode and we can continue with the interface configuration.

Configuring access & trunk ports

  To configure an interface to be an access interface, the switchport mode acess interface command is used. This type of interface can be assigned only to a single VLAN.     To configure a trunk interface, the switchport mode trunk interface command is used. This type of interface can carry traffic of multiple VLANs. […]

FTP & TFTP

FTP (File Transfer Protocol) FTP is a network protocol used to transfer files from one computer to another over a TCP network. Like Telnet, it uses a client-network arhitecture, which means that a user has to have an FTP client installed to access an FTP server running on the remote machine. After establishing an FTP […]

HTTP & HTTPS

HTTP (Hypertext Transfer Protocol) HTTP is an client-server protocol that allows clients to request web pages from web servers. It is an application level protocol widely used on the Internet. Clients are usually web browsers. When a user wants to access a web page, a browser sends an HTTP Request message to the web server. […]
