10.2.1 Logging In
Password Logging in to X4000 can be done in several ways as described in chapter 4.2,
page 76 , but is always protected by a password. Every unsuccessful attempt to
log in is logged with the source of the attempt by a syslog message and creates
a corresponding SNMP trap. Pauses are inserted after several unsuccessful
attempts to make it difficult for automatic attempts to find the password.
