Setting passwords
4
Enter the command to disable SNMP management of the device.
BigIron RX(config)#no snmp-server enable
Enter the command to later re-enable SNMP management of the device.
BigIron RX(config)#snmp-server enable
Syntax: [no] snmp-server enable
Setting passwords
Passwords can be used to secure the following access methods:
•
Telnet access can be secured by setting a Telnet password. Refer to
“Setting a Telnet
password”
on page 71.
•
Access to the Privileged EXEC and CONFIG levels of the CLI can be secured by setting
passwords for management privilege levels. Refer to
“Setting passwords for management
privilege levels”
on page 72.
This section also provides procedures for enhancing management privilege levels, recovering from
a lost password, and disabling password encryption.
NOTE
You also can configure up to 16 user accounts consisting of a user name and password, and assign
each user account a management privilege level. Refer to
“Setting up local user accounts”
on
page 75.
Setting a Telnet password
By default, the device does not require a user name or password when you log in to the CLI using
Telnet.
To set the password “letmein” for Telnet access to the CLI, enter the following command at the
global CONFIG level.
BigIron RX(config)# enable telnet password letmein
Syntax: [no] enable telnet password <string>
Suppressing Telnet connection rejection messages
By default, if a device denies Telnet management access to the device, the software sends a
message to the denied Telnet client. You can optionally suppress the rejection message. When you
enable the option, a denied Telnet client does not receive a message from the device. Instead, the
denied client simply does not gain access.
To suppress the connection rejection message sent by the device to a denied Telnet client, enter
the following command at the global CONFIG level of the CLI.
BigIron RX(config)# telnet server suppress-reject-message
Syntax: [no] telnet server suppress-reject-message
