ROUBLESHOOTING

Check that the community strings configured for the device and the Network Manager

are the same.

Check that SNMP access was not disabled for the system.

Permanent entries remain in the FDB:

If you have made a permanent entry in the FDB (which requires you to specify the

VLAN to which it belongs and then delete the VLAN), the FDB entry will remain.

Though causing no harm, you must manually delete the entry from the FDB if you

want to remove it.

Default and Static Routes:

If you have defined static or default routes, those routes will remain in the

configuration independent of whether the VLAN and VLAN IP address that used them

remains. You should manually delete the routes if no VLAN IP address is capable of

using them.

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

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 1:1,1:2

ERROR: Protocol conflict on port 1:5

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.
