How does a Cisco router enter port 6890?

I don't understand what the landlord means, what to do when entering the Cisco 6890 port, the general control Cisco equipment can be operated directly through the console port, or through telnet, which needs to be set VTY password and global enable password to enter.

The easiest setup is to open all ports.

1. The broadband network cable or the network cable out of the cat is connected to the WAN port of the router, and the LAN port is connected to the computer.

2. After starting the device, open the browser and enter it in the address bar to enter the wireless router settings interface. (If you can't get in, please look at the nameplate at the bottom of the router or the router instruction manual, the default settings of different models of routers are different.) ）

3. An account and password to log in to the router appear in the settings interface, enter the default account and password admin, or refer to the manual;

4. After successful login, select the interface of the setup wizard, which will automatically pop up by default;

5. After selecting the setup wizard, a window will pop up to explain that you can set the basic parameters of the router through the wizard, and click Next directly;

6. Set up step by step according to the setup wizard, select the Internet mode, usually ADSL users choose the first PPPoE, if you use other network service providers, select the following two according to the actual situation, if you don't know how to choose, directly select the first item to automatically select, convenient for novice operations, click next after selection;

7. Enter the account and password applied for from the network service provider, and go directly to the next step after the input is completed;

8. Set the wifi password, try to make the alphanumeric combination more complicated, and it is not easy to be rubbed off the network.

9. After entering correctly, it will prompt whether to restart the router, select Yes to confirm the restart of the router, and you can access the Internet normally after restarting the router.

Run the no sh command to enable it in port mode.

The default ports are all enabled.

In the interface configuration mode of the router, first use no ip add to remove the IP address of the interface, because the IP address of the primary interface cannot be configured in the sub-interface mode.

Then use the command int f0 in global configuration mode to enter the subinterface configuration mode, where f0 0 is a physical interface, and . 1 is the number of the sub-interface, which can be numbered from 1 to 2 to the power of 32;

In sub-interface mode, you can set configurations such as IP addresses and VLAN encapsulation.

If you want to use a sub-interface, don't set the ip specific :conf t on the main interface

int f0/0

no ip add

int f0 can be f0 and so on.

Next, you can configure the details of the specific sub-interface.

Global mode inter f0 0

Enter the interface encap dot1q vlan vlanid

Good luck.
