Network Management
5-9
The Management VLAN uses a default tag value of 1. The Management VLAN is used to
distinguish VLAN traffic flows. The trunk port marks the frames with special tags as they
pass between the AP-5131 and its destination, these tags help distinguish data traffic.
Authentication servers (such as Radius and Kerberos) must be on the same Management
VLAN. Additionally, DHCP and BOOTP servers must be on the same Management VLAN as
well.
9. Define a Native VLAN Tag.
A trunk port configured with 802.1Q tagging can receive both tagged and untagged traffic.
By default, the AP-5131 forwards untagged traffic with the native VLAN configured for the
port. The Native VLAN is VLAN 1 by default. Symbol suggests leaving the Native VLAN set
to 1 as other layer 2 devices also have their Native VLAN set to 1.
10. Use the checkboxes under the name of each VLAN to map specific VLANs to AP-5131
WLANs listed on the left-hand side of the screen.
Symbol recommends mapping VLANs strategically in order to keep VLANs tied to the
discipline they most closely match. For example, If WLAN2 is comprised of MUs supporting
the engineering area, then WLAN2 should be mapped to the engineering VLAN if one has
been created.
11. Select the Dynamic checkbox to configure the VLAN mapping as a dynamic VLAN.
Using Dynamic VLAN assignments, a VMPS (VLAN Management Policy Server) dynamically
assigns VLAN ports. The AP-5131 uses a separate server as a VMPS server. When a frame
arrives on the AP-5131, it queries the VMPS for the VLAN assignment based on the source
MAC address of the arriving frame.
If statically mapping VLANs, leave the Dynamic checkbox specific to the target WLAN and
its intended VLAN unselected. The administrator is then required to configure VLAN
memberships manually.
The Dynamic checkbox is enabled only when a WLAN is having EAP security configured.
Otherwise, the checkbox is disabled.
12. Click Apply to return to the VLAN Name screen. Click OK to return to the LAN screen. Once
at the LAN screen, click Apply to re-apply your changes.
