Configuration Guidelines for use of IPv6 for out-of-band management of the
node
• The management port on the management router instance only supports host functionality.
• It is necessary to have an IPv4 address configured in the bof file. A bof file that contains
only IPv6 addresses is not supported.
• IPv6 duplicate address detection is not supported.
• IPv6 auto-configuration is not supported.
• IPv6 over IPv4 tunneling is not supported.
• IPv6 path MTU discovery is not supported.
• Router discovery option is not supported on the management port.
Security for Console Port and Ethernet Management Port
The 7210 OS supports disabling the console port and out-of-band Ethernet management port. In
remote deployments, operators can choose to disable user access to the node through the console
and through the ethernet management port to prevent unauthorized and malicious access.
Operators can use the command bof> console-disabled to disable the console and the command
bof> eth-mgmt-disabled to disable the use of Ethernet management port.
Note: Access to console is only disabled when the Timos image is loaded. Console access remains
unchanged during boot loader stage of the boot up process.
Reset the node to factory default setting
From release 4.0 and onwards, the default BOF password can be modified by the user. To edit the
BOF parameters, user needs to provide the correct password. If the user forgets the password and
fails to provide a correct password after three attempts, the system prompts the user to reset the
BOF password to factory default. As a security measure, to prevent a malicious user from using it
to gain access to the configuration files, when the password is reset to default, the system also
resets the flash to factory defaults (that is, it removes all the files from the flash except for the boot
image file (cf1:\boot.tim) and Timos image file (cf1:\both.tim)) and reboots the node with the
factory default settings. The node is rebooted after the password is reset, to boot up with the
factory default settings. After boot up, the user needs to setup the box using the same steps as used
to boot the box the first time when it was received from the factory. User can use the factory
default password ‘password’ to edit the BOF parameters after the boot up subsequent to reboot
and choose to change the password again. The bof password can be changed only in the Timos
CLI.
