Special security features

There are special security features that allow enabling and disabling of the recovery password,
establishing of incoming and outgoing telnet connections, copying gateway configurations while
keeping configuration secrets, and configuring of the SYN cookies for preventing SYN attacks.

Enabling and disabling recovery password

The G250/G350 includes a special recovery password. The purpose of the recovery password
is to enable the system administrator to access the G250/G350 in the event that the regular
password is forgotten. You can only use the recovery password when accessing the G250/
G350 via a direct connection to the console port.
Use the set terminal recovery password command to enable or disable the recovery
password. Use this command only when accessing the G250/G350 via a direct connection to
the console port.
