Map VLANs to IEEE 802.1 Q VLANs
Introduction
Each VLAN in the Express 500 series switches can be mapped to a sin-
gle 802.1 Q VLAN (one-to-one). This enables VLANs in the two envi-
ronments to recognize frames from the corresponding “mapped”
environment. When 802.1 Q VLAN tagging is enabled, only tagged
frames passing through the 1000Base-SX port are forwarded. Tagged
frames received on the front ports of the Express 500 series switch are
discarded.
The VLANs are mapped using the Express 500 series VLAN name and
a unique 802.1.Q VLAN ID.
When the mapping feature is disabled, tagged frames received by the
Express 500 series switch are forwarded without any tag recognition oc-
curring.
