TROUBLESHOOTING

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.

VLANS

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 <name>

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
