You forget your password and cannot log in:
If you are not an administrator, another user having administrator 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 administrator access level can log in and initialize the
device. This will return all configuration information (including passwords) to the
initial values.
In the case where no one knows a password for an administrator level user, contact
your supplier.
VLAN S
You cannot add a port to a VLAN:
If you attempt to add a port to a VLAN and get an error message similar to
localhost:7 # config vlan marketing add port 1,2
ERROR: Protocol conflict on port 5
you already have a VLAN using untagged traffic on a port. Only one VLAN using
untagged traffic can be configured on a single physical port. VLAN configuration can
be verified by using the command
show vlan
The solution for this error is to remove ports 1 and 2 from the VLAN currently using
untagged traffic on those ports. If this were the “default” VLAN, the command would
be
localhost:23 # config vlan default del port 1,2
which should now allow you to re-enter the previous command without error as
follows:
localhost:26 # config vlan red add port 1,2
