Specifying the maximum number of login attempts for
Telnet access
If you are connecting to the device using Telnet, the device prompts you for a username and
password. By default, you have up to 3 chances to enter a correct username and password. If you
do not enter a correct username or password after 3 attempts, the device disconnects the Telnet
session.
You can specify the number of attempts a Telnet user has to enter a correct username and
password before the device disconnects the Telnet session. For example, to allow a Telnet user up
to 3 chances to enter a correct username and password, enter the following command:
BigIron RX(config)# telnet login-retries 5
Syntax: [no] telnet login-retries <number>
You can specify from 0 – 3 attempts. The default is 3 attempts.
