Solving Command Line Interface Problems 133
The System Time is inaccurate
Check that:
■
The Webcache system time is configured to be set through the
Network Time Protocol (NTP).
■
NTP is enabled on the Webcache. If it is enabled, ping the NTP server
that you have specified to check that it is operational.
If the NTP server is not functional, or you are not confident it is
working correctly, try using another NTP server.
■
The timezone is set correctly.
Alternatively, the Webcache system time can be set manually. If you have
configured the system time manually and it is inaccurate, the Webcache
clock has probably drifted over time. 3Com recommends that you use the
Network Time Protocol to prevent this. If this is not possible, reset the
system time manually using the Time Configuration window. Also check
that the timezone is set correctly.
The Webcache fails to power-up
Check that:
■
The Power/Self Test LED on the front panel is Yellow or Off, possibly
indicating a system error. If so, contact 3Com support personnel.
■
If no front panel LEDs are lit, check the power connection to the
Webcache.

Problems
The Command Line Interface responds slowly to commands.
This is probably due to large amounts of traffic on the network. Logout
and then login again later when the amount of traffic to the Webcache is
less.
You forget the password for the admin user name and can no
longer perform important management operations.
Use the password recovery method outlined on page 73 to define a new
password for the admin user name.
