Now the Managed Media Converter is configured to pass all data between the OPTICS (or
UPLINK) and DATA ports except that which is tagged with VLAN ID 7. All data tagged
with VLAN ID 7 is considered management traffic and passes from the OPTICS (or UPLINK)
port to the EXT MGMT port only. The Managed Media Converter is configured to receive
untagged data from the twisted pair EXT MGMT port and add the VLAN ID 7 before sending
it out of the OPTICS (or UPLINK) port.
