Using The Switch - 3Com SuperStack II 3000 TX User Manual

Check that the port through which you are trying to
access the device is in VLAN 1 (the Default VLAN).
Refer to "Setting Up VLANs on the Switch"
5-8.
Try accessing the device through a different port. If
you can now access the device, a problem with the
original port is indicated. Re-examine the connec-
tions and cabling.
There may be a network problem preventing you
accessing the device over the network. Try access-
ing the device through the console port.
You forget your password and cannot log in:
If you are not one of the default users (monitor,
manager, security, or admin), another user having
security access level can log in, delete your user
name, and create a new user name for you, with a
new password.
Alternatively, another user having security access
level can log in and initialize the device. This will
return all configuration information, including pass-
words, to the initial values. In the case where
no-one knows a password for a security level user,
contact your supplier.

You have configured a Switch port so that it
'blips' when a broadcast storm occurs, but the
port does not blip properly:
The broadcast storms are occurring such that the
average broadcast bandwidth cannot drop below
the Falling Threshold value. This means that the
blip only occurs once.
Try changing the following attributes in the Broad-
cast Storm Control section of the Port Setup screen:
