Network Engineering Stack Exchange is a question and answer site for network engineers. It only takes a minute to sign up. In setting up a new network switch Catalyst SI did the initial configuration dialog via the console portin which it asks for host-name, secret, password, virtual terminal password, and other things.

I set the enable secret, the enable password, and the virtual terminal password. At no point does it ask for a username. Is the password one of the three mentioned above that it asks me to create during setup?

Is it some default value? Is the username something like "cisco" or "admin"? The "getting started guide" suggests that the initial web-interface default password is cisco and that it ignores the username field. I tried that. These get deleted after the first time you login to the switch. There shouldn't be any access control on the console, unless the express setup puts it in there. Now, if you set the virtual terminal password, then it probably just set a password on the line vty block, this should let you in with Telnet without needing a username.

Once you get in to the switch with telnet you can run sh run inc username. This will tell you what the username is set as, and probably the password if you don't have the password-encryption service on. If this fails to work, then you will have to do a password recovery on the switch. The admin or whatever setup wizard used has to configure authentication to have and check user and password. Without a password set on the vty -- or AAA configuration, the only allowed access is via the console.

And the console will require no authentication. Sign up to join this community. The best answers are voted up and rise to the top. Home Questions Tags Users Unanswered. Cisco default username Ask Question. Asked 5 years, 4 months ago. Active 3 years, 8 months ago.

I have tried for username: cisco, admin, administrator, and now cisco after your suggestion. Aw Mike, where's your sense of adventure? Its because you have login local set on the VT ports or console port.

Cisco Default Password List

Along with this password, like most Cisco devicesthe SG uses the default username of cisco to login with administrative privileges. It needs to be entered into the web browser's navigation bar where URLs go. Default passwords are sometimes different for certain hardware or firmware versions, but what's described above should work for any SG switch.

It's important to secure any managed network hardware by changing the default login information. If you don't, anyone with network access can be granted administrator rights. If you took this step, the above information won't work. However, if you don't remember what you changed the password to, reset it to the factory defaults to restore the username and password to cisco. Resetting is not the same as restarting the switch.

The former restores the username and password, while the latter shuts down the switch and then starts it back up. Make sure your SG is powered on and then turn it to its backside so you can see the cables. Find the small hole on the back the Reset button and press and hold it for 5 to 10 seconds with something pointed, like a paperclip or pin.

Change the default switch password to something more secure. See these examples of a strong password if you're not sure how to make one. Store the new, strong password in a password manager so that it's easier to remember. If For most networks, if your switch's default IP address was changed, the new IP address can be determined using tracerta command available from the Command Prompt in Windows. Resetting the SG switch restores the username and password and also the default IP address.

If you can't access the switch using its IP address after a full reset, there's probably an issue with its physical connection. Trace the device's cables from the switch outward to find missing connections or bad wires.

The Cisco SG Support page on the Cisco website is the official location of all things related to the switch, be it downloads, videos, or documentation.

From this link, you can find the Cisco SG Downloads page in the Downloads tabwhere you can get the latest firmware and managed switch MIB downloads. All of the firmware files use the ROS file extensionbut depending on the version you download, you might get it in a ZIP archive that you have to open before finding the firmware file.

Switches that are available as different hardware versions usually use unique firmware, making it important to download the right one for your device. The Cisco SG switch, however, doesn't have other hardware versions, so the firmware you find through the link above is the same firmware for all SG switches.

The Cisco SG Documentation page through the Documentation tab holds the brochures, command references, datasheets, install and upgrade guides, release notes, and other related documents for the device.With several different user accounts, you can also set different privilege level for each one of them. Different privilege means different available commands that can be executed per user account. In this article, we will go deep on creating users accounts and all its features including privilege, encryption, and automation that we can implement in Cisco IOS devices.

This article shows how you can manage user accounts and passwords in Cisco IOS devices. Basically you will need to create at least a user account in your Cisco router or switch if:.

The standard command to create user account and password in Cisco IOS is shown in the example below, and it must be executed in global configuration mode. With above configuration you have successfully created username Cisco IOS device. However, there is one major weakness in this configuration and it will be explained in this sub-section below. When you define a password, it is stored with clear-text format in your running-configuration.

In the show running-config output, the password will be shown as it is:. Notice that your password phrase is explicitly written there. To solve this issue, we can apply encryption to the password and hide the exact passphrase. There are two types of encryption:. With the command service password-encryptionall existing and future added passwords will be automatically encrypted.

As you can see above, password phrase in the show running-config output has been masked by a random numbers and letters. It using MD5 algorithm to hide your original passphrase. To use type 5 encryption to secure passwords in Cisco IOS devices we can simply create username followed by a secret instead of password.

The configuration will be demonstrated in the next example but first we will delete the username and password created earlier:. And with this configuration we will re-create username using a secret :. In this section we will enforce login to the console command line.

By issuing command login above, we told the device to always ask credential to any attempt of accessing the console command line. The word local is telling the device to look up its internal user account database for authentication, which means the device will refer to the list of username we created before. Now the device will ask for login credential on the next attempt of accessing CLI via console line. You cannot enter configuration mode except from privileged EXEC mode. With the configuration below we will set authentication on any attempt to enter privileged EXEC mode using the enable command:.

As the result of this configuration, now a passphrase will be asked before we entering the privileged EXEC mode. We can enforce login on the remote access with similar configuration as the one we applied in the console line anyway, it is mandatory to have username and password in terminal line if we want to enable SSH With this configuration below we will enforce login to virtual terminal line:.

By default all user accounts are created using privilege level 1 and it is equivalent with user EXEC mode. When we use the command enablewe will be granted with privilege level 15 by default, and privilege level 15 has access to all configurations and commands.

We can create custom privilege level between 1 and By default if we assign any privilege level to a user account it will bypass the user EXEC mode. In this example we are going to create a new user account with privilege level 7. But as you can see in the screenshot below, the command configure terminal that we use to enter global configuration mode is not recognized.

Now in this example we will allow everybody with privilege level 7 to do something at the interface level, which is giving a description.

Disabling password recovery will not work if you have set the switch to boot up manually by using the boot manual global configuration command.

This command produces the boot loader prompt switch: after the switch is power cycled. A simple way of providing terminal access control in your network is to use passwords and assign privilege levels. Password protection restricts access to a network or network device. Privilege levels define what commands users can enter after they have logged into a network device.

No password is defined. The default is level 15 privileged EXEC level. The password is not encrypted in the configuration file. The password is encrypted before it is written to the configuration file. To provide an additional layer of security, particularly for passwords that cross the network or that are stored on a Trivial File Transfer Protocol TFTP server, you can use either the enable password or enable secret global configuration commands.

Both commands accomplish the same thing; that is, you can establish an encrypted password that users must enter to access privileged EXEC mode the default or any privilege level you specify. We recommend that you use the enable secret command because it uses an improved encryption algorithm. If you configure the enable secret command, it takes precedence over the enable password command; the two commands cannot be in effect simultaneously.

If you enable password encryption, it applies to all passwords including username passwords, authentication key passwords, the privileged command password, and console and virtual terminal line passwords.

By default, any end user with physical access to the switch can recover from a lost password by interrupting the boot process while the switch is powering on and then by entering a new password. The password-recovery disable feature protects access to the switch password by disabling part of this functionality. When this feature is enabled, the end user can interrupt the boot process only by agreeing to set the system back to the default configuration.

With password recovery disabled, you can still interrupt the boot process and change the password, but the configuration file config. If you disable password recovery, we recommend that you keep a backup copy of the configuration file on a secure server in case the end user interrupts the boot process and sets the system back to default values.

Do not keep a backup copy of the configuration file on the switch. If the switch is operating in VTP transparent mode, we recommend that you also keep a backup copy of the VLAN database file on a secure server.

When the switch is returned to the default system configuration, you can download the saved files to the switch by using the Xmodem protocol. To re-enable password recovery, use the service password-recovery global configuration command. When you power-up your switch for the first time, an automatic setup program runs to assign IP information and to create a default configuration for continued use. The setup program also prompts you to configure your switch for Telnet access through a password.

If you did not configure this password during the setup program, you can configure it when you set a Telnet password for a terminal line. You can configure username and password pairs, which are locally stored on the switch.

These pairs are assigned to lines or ports and authenticate each user before that user can access the switch.Obtaining Documentation and Submitting a Service Request.

Default password for Cisco Catalyst 3850

You can also set administrator usernames and passwords to manage and configure one or more access points that are associated with the switch.

You can set strong administrator passwords such as encrypted passwords with ASCII keys for the administrator user for managing access points. There should be at least three of the following categories—lowercase letters, uppercase letters, digits, and special characters.

The new password should not be the same as that of the associated username and the username should not be reversed. The characters in the password should not be repeated more than three times consecutively. The password should not be ciscoocsicadminnimdaor any variant obtained by changing the capitalization of letters therein, or by substituting "1" " " or "!

The maximum number of characters accepted for the username and password is Randomly generated key—This key is generated randomly and it is the most secure option. To export the configuration file from one system to another, the key should also be exported. Static key—The simplest option is to use a fixed static encryption key. By using a fixed key, no key management is required, but if the key is somehow discovered, the data can be decrypted by anyone with the knowledge of that key.

This is not a secure option and it is called obfuscation in the CLI. User defined key—You can define the key by yourself. To export the configuration file from one system to another, both systems should have the same key configured. The administrator can configure the switch and view the configured information. Specifies administrator username and password for managing all of the access points configured to the switch.
