C-4 APPENDIX C: TROUBLESHOOTING
You forget your password and cannot log on:
If you are not an administrator, another user having administrator
access level can log on, 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 the following:
localhost:7 # config vlan marketing add port 1,2
ERROR: Protocol conflict.
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 was 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:
localhost:26 # config vlan red add port 1,2
