Enable AAA accounting
To record information about all user-entered commands, use the AAA accounting feature — not supported for RADIUS accounting. AAA
accounting records login and command information in OS10 sessions on console connections using the console option and remote
connections using the default option, such as Telnet and SSH.
AAA accounting sends accounting messages:
• Sends a start notice when a process begins, and a stop notice when the process ends using the start-stop option
• Sends only a stop notice when a process ends using the stop-only option
• No accounting notices are sent using the none option
• Logs all accounting notices in syslog using the logging option
• Logs all accounting notices on congured TACACS+ servers using the group tacacs+ option
Enable AAA accounting
• Enable AAA accounting in CONFIGURATION mode.
aaa accounting commands all {console | default} {start-stop | stop-only | none} [logging]
[group tacacs+]
The no version of this command disables AAA accounting.
Enable user lockout
By default, a maximum of three consecutive failed password attempts is supported on the switch. You can set a limit to the maximum
number of allowed password retries with a specied lockout period for the user ID.
This feature is available only for the sysadmin and secadmin roles.
• Congure user lockout settings in CONFIGURATION mode.
password-attributes {[max-retry number ] [lockout-period minutes]}
– max-retry number — Sets the maximum number of consecutive failed login attempts for a user before the user is locked out,
from 0 to 16; default 3.
– lockout-period minutes — Sets the amount of time that a user ID is prevented from accessing the system after exceeding
the maximum number of failed login attempts, from 0 to 43,200; default 0.
When a user is locked out due to exceeding the maximum number of failed login attempts, other users can still access the switch.
By default, lockout-period minutes is 0; no lockout period is congured. Failed login attempts do not lock out a user.
Congure user lockout
OS10(config)# password-attributes max-retry 4 lockout period 360
Limit concurrent login sessions
To avoid an unlimited number of active sessions on a switch for the same user ID, you can limit the number of console and remote
connections. Log in from a console connection by cabling a terminal emulator to the console serial port on the switch. Log in to the switch
remotely through a virtual terminal line (VTY), such as Telnet and SSH.
• Congure the maximum number of concurrent login sessions in CONFIGURATION mode.
OS10(config)# login concurrent-session limit number
620
