no username <username> [capability | disable [login | password] | full-name]

Creates a user and sets its capabilities, password and name.

The no form of the command deletes the user configuration.

Syntax Description

username

Specifies a username and creates a user account. New users are created initially with admin privileges but is disabled.

Allowed characters for the username:

a-z
A-Z
0-9
period (.), underscore (_), hyphen (-)

Any single character or combination of characters from the above is allowed except for a period "." in a single form.

capability <cap>

Defines user capabilities.

admin—full administrative capabilities
monitor—read only capabilities, can not change the running configuration
unpriv—can only query the most basic information, and cannot take any actions or change any configuration
v_admin—basic administrator capabilities

disable [login | password]

Disable—disable this account
Disable login—disable all logins to this account
Disable password—disable login to this account using a local password

disconnect

Logs out the specified user from the system.

name

Full name of the user.

nopassword

The next login of the user will not require password.

0 | 7

0—specifies a login password in cleartext
7—specifies a login password in encrypted text

password

Specifies a password for the user in string form. If [0 | 7] was not specified then the password is in cleartext.

Default

The following usernames are available by default:

admin
monitor

Notes

To enable a user account, just set a password on it (or use the command “username <user> nopassword” to enable it with no password required for login)
Removing a user account does not terminate any current sessions that user has open; it just prevents new sessions from being established
Encrypted password is useful for the command “show configuration”, since the cleartext password cannot be recovered after it is set
The command "username <user> password <password>" or "username <user> password 0 <password>" are not security and will leave clear text in user's terminal (log and command history will be treated as sensitive information without clear text password). They are recommended to be replaced as "username <user> password" or "username <user> password" commands.

AAA Methods

aaa accounting

	aaa accounting changes default stop-only tacacs+ no aaa accounting changes default stop-only tacacs+ Enables logging of system changes to an AAA accounting server. The no form of the command disables the accounting.
Syntax Description	N/A
Default	N/A
Configuration Mode	config
History	3.1.0000
Example	switch (config) # aaa accounting changes default stop-only tacacs+
Related Commands	show aaa
Notes	TACACS+ is presently the only accounting service method supported Change accounting covers both configuration changes and system actions that are visible under audit logging, however this feature operates independently of audit logging, so it is unaffected by the commands “logging level audit mgmt” or “configuration audit” Configured TACACS+ servers are contacted in the order in which they appear in the configuration until one accepts the accounting data, or the server list is exhausted Despite the name of the “stop-only” keyword, which indicates that this feature logs a TACACS+ accounting “stop” message, and in contrast to configuration change accounting, which happens after configuration database changes, system actions are logged when the action is started, not when the action has completed

aaa authentication login

	aaa authentication login default <auth method> [<auth method> [<auth method> [<auth method> [<auth method>]]]] no aaa authentication login Sets a sequence of authentication methods. Up to four methods can be configured. The no form of the command resets the configuration to its default.
Syntax Description	auth-method	local radius tacacs+ ldap
Default	local
Configuration Mode	Any command mode
History	3.1.0000 3.7.1102—Updated notes
Example	switch (config) # aaa authentication login default radius tacacs+ ldap local
Related Commands	show aaa
Notes	The order in which the methods are specified is the order in which the authentication is attempted. It is recommended that “local” is one of the methods selected. When defining a remote server that to authenticate users against, once a connection is established with it, it does not go through other authentication methods. Meaning, if local is defined first, it will not go to other methods. If a remote server is defined first and then local (radius → local), then if the radius server is reachable, the response from this server will dictate whether the switch can be accessed or not (regardless of whether the user exists on any other authentication mothod).

aaa authentication attempts fail-delay

	aaa authentication attempts fail-delay <time> no aaa authentication attempts fail-delay Configures delay for a specific period of time after every authentication failure. The no form of the command resets the fail-delay to its default value.
Syntax Description	time	Range: 0-60 seconds
Default	0
Configuration Mode	config
History	3.5.0200
Example	switch (config) # aaa authentication attempts fail-delay 1
Related Commands
Notes

aaa authentication attempts track

	aaa authentication attempts track {downcase \| enable} no aaa authentication attempts track {downcase \| enable} Configure tracking for failed authentication attempts. The no form of the command clears configuration for tracking authentication failures.
Syntax Description	downcase	Does not convert all usernames to lowercase (for authentication failure tracking purposes only).
Syntax Description	enable	Disables tracking of failed authentication attempts.
Default	N/A
Configuration Mode	config
History	3.5.0200
Example	switch (config) # aaa authentication attempts track enable
Related Commands
Notes	This is required for the lockout functionality described below, but can also be used on its own for informational purposes. Disabling tracking does not clear any records of past authentication failures, or the locks in the database. However, it does prevent any updates to this database from being made: no new failures are recorded. It also disables lockout, preventing new lockouts from being recorded and existing lockouts from being enforced.

aaa authentication attempts lockout

	aaa authentication attempts lockout {enable \| lock-time \| max-fail \| unlock-time} no aaa authentication attempts lockout {enable \| lock-time \| max-fail \| unlock-time} Configures lockout of accounts based on failed authentication attempts. The no form of the command clears configuration for lockout of accounts based on failed authentication attempts.
Syntax Description	enable	Enables locking out of user accounts based on authentication failures. This both suspends enforcement of any existing lockouts, and prevents any new lockouts from being recorded. If lockouts are later re-enabled, any lockouts that had been recorded previously resume being enforced; but accounts which have passed the max-fail limit in the meantime are NOT automatically locked at this time. They would be permitted one more attempt, and then locked, because of how the locking is done: lockouts are applied after an authentication failure, if the user has surpassed the threshold at that time. Lockouts only work if tracking is enabled. Enabling lockouts automatically enables tracking. Disabling tracking automatically disables lockouts.
	lock-time	Sets maximum permitted consecutive authentication failures before locking out users. Unlike the “max-fail” setting, this does take effect immediately for all accounts. If both unlock-time and lock-time are set, the unlock-time must be greater than the lock-time. This is not based on the number of consecutive failures, and is therefore divorced from most of the rest of the tally feature, except for the tracking of the last login failure.
	max-fail	Sets maximum permitted consecutive authentication failures before locking out users. This setting only impacts what lockouts are imposed while the setting is active; it is not retroactive to previous logins. So if max-fail is disabled or changed, this does not immediately cause any users to be changed from locked to unlocked or vice versa.
	unlock-time	Enables the auto-unlock of an account after a specified number of seconds if a user account is locked due to authentication failures, counting from the last valid login attempt. Unlike the “max-fail” setting, this does take effect immediately for all accounts. If both unlock-time and lock-time are set, the unlock-time must be greater than the lock-time. Careful with disabling the unlock-time, particularly if you have max-fail set to something, and have not overridden the behavior for the admin (i.e. they are subject to lockouts also). If the admin account gets locked out, and there are no other administrators who can aid, the user may be forced to boot single-user and use the pam_tallybyname command-line utility to unlock your account manually. Even if one is careful not to incur this many authentication failures, it makes the system more subject to DOS attacks.
Default	N/A
Configuration Mode	config

aaa authentication attempts class-override

	aaa authentication attempts class-override {admin [no-lockout] \| unknown {no-track \| hash-username}} no aaa authentication attempts class-override {admin \| unknown {no-track \| hash-username}} Overrides the global settings for tracking and lockouts for a type of account. The no form of the command removes this override and lets the admin be handled according to the global settings.
Syntax Description	admin	Overrides the global settings for tracking and lockouts for the admin account. This applies only to the single account with the username “admin”. It does not apply to any other users with administrative privileges.
	no-lockout	Prevents the admin user from being locked out though authentication failure history is still tracked (if tracking is enabled overall).
	unknown	Overrides the global settings for tracking and lockouts for unknown accounts. The “unknown” class here contains the following categories: Real remote usernames which simply failed authentication Mis-typed remote usernames Passwords accidentally entered as usernames Bogus usernames made up as part of an attack on the system
	hash-username	Applies a hash function to the username and stores the hashed result in lieu of the original
	no-track	Does not track authentication for such users (which of course also implies no-lockout)
Default	N/A
Configuration Mode	config
History	3.2.3000

aaa authorization

	aaa authorization map [default-user <username> \| order <policy> \| fallback] no aaa authorization map [default-user \| order \| fallback] Sets the mapping permissions of a user in case a remote authentication is done. The no form of the command resets the attributes to default.
Syntax Description	username	Specifies what local account the authenticated user will be logged on as when a user is authenticated (via RADIUS or TACACS+ or LDAP) and does not have a local account. If the username is local, this mapping is ignored.
	order <policy>	Sets the user mapping behavior when authenticating users via RADIUS or TACACS+ or LDAP to one of three choices. The order determines how the remote user mapping behaves. If the authenticated username is valid locally, no mapping is performed. The setting has the following three possible behaviors: local-only—maps all remote users to the user specified by the command “aaa authorization map default-user <user name>”. Any vendor attributes received by an authentication server are ignored. remote-first—if a local-user mapping attribute is returned and it is a valid local username, it maps the authenticated user to the local user specified in the attribute. Otherwise, it uses the user specified by the default-user command. remote-only—maps a remote authenticated user if the authentication server sends a local-user mapping attribute. If the attribute does not specify a valid local user, no further mapping is tried.
	fallback	Sets the authenticating fallback behavior via RADIUS or TACACS+ or LDAP. This option attempts to authenticate username through the next authentication method listed in case of an error. server-err—performs fallback if an error occurs while connecting to remote AAA server (e.g., server is down, not responding, and so forth)
Default	Default user—admin Map order—remote-first Order fallback—server-err
Configuration Mode	config
History	3.1.0000 3.7.1000—Added “fallback” parameter 3.7.1000—Updated syntax
Example	switch (config) # aaa authorization map default-user admin
Related Commands	show aaa username
Notes	If, for example, the user is locally defined to have admin permission, but in a remote server such as RADIUS the user is authenticated as monitor and the order is remote-first, then the user is given monitor permissions. The user must be careful when disabling AAA authorization map fallback server-err, because if the remote server stops working then the user may lock themselves out. If AAA authorization order policy is configured to remote-only, then when upgrading to 3.4.3000 or later from an older version, this policy is changed to remote-first.

The no form of the command resets the attribute to its default value.
Syntax Description	options	This command specifies the list of supplemental certificates of authority (CAs) from the certificate configuration database that is to be used by LDAP for authentication of servers when in TLS or SSL mode. The options are: default-ca-list—uses default supplemental CA certificate list none—no supplemental list, uses the built-in one only CA certificates are ignored if “ldap ssl mode” is not configured as either “tls” or “ssl”, or if “no ldap ssl cert-verify” is configured. The default-ca-list is empty in the factory default configuration. Use the command: “crypto certificate ca-list default-ca-list name” to add trusted certificates to that list. The “default-ca-list” option requires LDAP to consult the system’s configured global default CA-list for supplemental certificates.
	cert-verify	Enables verification of SSL/TLS server certificates. This may be required if the server's certificate is self-signed, or does not match the name of the server.
	ciphers {all \| TLS1.2}	Sets SSL mode to be used
	crl-check enable	Enables LDAP CRL check
	crl-check file fetch	Fetches CRL from remote server. CRL must be a valid PEM file unless a proper message shown. Supported formats: SCP, HTTP, HTTPS, FTP, and FTPS.
	mode	Sets the security mode for connections to the LDAP server. none—requests no encryption for the LDAP connection ssl—the SSL-port configuration is used, an SSL connection is made before LDAP requests are sent (LDAP over SSL) start-tls—the normal LDAP port is used, an LDAP connection is initiated, and then TLS is started on this existing connection
	vrf-name	VRF to be affected. If "vrf-name" parameter is not specified, "default" VRF will be used.
	port-number	Sets the port on the LDAP server to connect to for authentication when the SSL security mode is enabled (LDAP over SSL)
Default	cert-verify—enabled mode—none (LDAP SSL is not activated) port-number—636 ciphers—all
Configuration Mode	config
History	3.1.0000
	3.2.3000	Added ca-list argument
	3.4.0000	Added “ssl ciphers” parameter and Updated example
	3.6.8008	Added the parameter “crl-check”

Example	switch (config) # ldap ssl crl-check file fetch scp://root:pass@1.1.1.1/etc/pki/crl.pem 100.0% [#####################################################################]
Related Commands	show aaa show ldap
Notes	If available, the TLS mode is recommended, as it is standardized, and may also be of higher security The port number is used only for SSL mode. If the security mode selected is TLS, the LDAP port number is used.
