Cisco PT Simulation Lab (3) vswitch Telnet Remote logon Configuration

Objective: To master the vty line configuration of a vswitch and implement remote management of the vswitch through telnet.

Tutorial Background: After you configure the switch for the first time in the equipment room, you can remotely manage the switch in the office or on a business trip. Configure the vswitch.

Technical Principles:

Configure the management IP address of the vswitch to ensure that the IP address of the computer and the management IP address of the vswitch are in the same CIDR block.

In a layer-2 switch, IP addresses are only used to remotely log on to the Management Switch. They are not required for the operation of the switch. However, if no management IP address is configured, the switch can only use the control port console for local configuration and management.

By default, all ports of a vswitch belong to VLAN1, and VLAN1 is automatically created and managed by the vswitch. Each VLAN has only one active management address, which is disabled by default and needs to be opened manually.

The permission levels on Cisco devices are from 0 ~ 15. The default Telnet mode is 1, and the maximum permission is 15. (Privilege level [0-15])

The login function is enabled for the vty line by default, which means you must set a password for it to log on.

Password 7 ***** cannot be used to set plain text. For example, if you set enable password cisco and encryption the service password-encryption command to enable encryption, you can see the enable password 70822455D0A16 in the configuration, where 0822455D0A16 is the ciphertext of the plaintext cisco encrypted.

It is equivalent to setting enable password 70822455D0A16 without enabling global password encryption. This ciphertext can be copied and used directly when backup configuration is restored. We can see that when you set password 7 *****, the password should be entered later.

Lab devices: Switch_2960, 1 PC, 2 configuration lines, and direct connections.

Tutorial topology:

Tutorial steps:

Enter VLAN port mode (interface vlan 1)

Configure the vswitch management ip address (IP address ***** ip ****** submask **)

Select a specific line configuration mode (line vty [0-15] [0-15])

Configure the logon password (password ******)

Manually enable VLAN1 port (no shutdown)

Connect the two PCs to the vswitch, and ensure that the IP address and the vswitch management IP address are in the same CIDR block.
