support port monitoring. You can set the securemon enable option.
admin commands are disabled except for read-only ID command required by
NS-Link to identify the device.

4606 while is in Secure Data Mode, and to allow NS-Link to operate through a MAC
connection with Secure Config Mode enabled and Secure Data Mode disabled.

• Requires password authentication – even if password is empty.
• Enabled/disabled along with telnet access independently of Secure Data and
Secure Config Modes.
