Console/Telnet Lockout Security

TD220MAX release 1.2.15 introduces a lockout on serial and telnet console logins after repeated
attempts fail. If an invalid login attempt is repeated 3 times on either console type, the console will no
longer display the login prompt for 5 minutes.
During this time, both serial and Telnet console logins are disabled (no matter which console was being
attacked) but existing console sessions will operate normally. If SNMP traps are enabled and/or a Syslog
server is configured, events recording the lockout will be sent to alert personnel to this possible attack.
After 5 minutes, both serial and Telnet consoles present the login prompt once again.
