I am eager for the first time to switch between vlan routing and nat addresses of Cisco switches. I am very energetic and have an undefeated spirit. I am ready to continue to answer questions during multiple rounds of interviews. My little brother squashed his eyes and took out the bottom of the press box: If my company has two Internet interfaces, A and B, respectively. The following vswitch divides multip

As shown in, Node switch 3550 is placed in an office room. The networks of all office companies are from this place. How does the operator configure network bandwidth settings for each company on this device? Let's take the IT Training Center of XX foreign companies as an example. The IT Training Center of XX foreign companies applied for a 2 m link.
