video demonstration of the show ip interface brief command

The show ip interface brief command is used in Cisco networking devices to display a summary of the configuration and status of all interfaces on the device. Here's a demonstration of the command:

1. First, log in to the Cisco device using the terminal or console connection.
2. Enter the privileged EXEC mode by typing enable and providing the enable password if required.
3. Type show ip interface brief and press Enter.

Here is an example output of the command:

objectivec
Router# show ip interface brief

Interface       IP-Address     OK? Method Status                Protocol
GigabitEthernet0/0    10.0.0.1     YES  NVRAM  up                    up      
GigabitEthernet0/1    192.168.1.1  YES  NVRAM  up                    up      
Serial0/0/0          unassigned   YES  NVRAM  down                  down    
Serial0/1/0          unassigned   YES  NVRAM  administratively down down 

In the example output above, there are four interfaces listed: GigabitEthernet0/0, GigabitEthernet0/1, Serial0/0/0, and Serial0/1/0. The columns provide the following information:

• Interface: the name of the interface
• IP-Address: the IP address assigned to the interface (if any)
• OK?: whether the interface is operational (YES) or not (NO)
• Method: the method used to assign the IP address to the interface (in this case, NVRAM)
• Status: the status of the interface (up or down)
• Protocol: the routing protocol currently in use on the interface (if any)

The output shows that GigabitEthernet0/0 and GigabitEthernet0/1 are both up and have IP addresses assigned to them, while Serial0/0/0 and Serial0/1/0 are both down and do not have IP addresses assigned to them.
