Configuring Lan1 And Lan2 Settings - Extreme Networks Altitude 3500 Series Product Reference Manual

8 Enter a Management VLAN Tag for LAN1 and LAN2.
The Management VLAN uses a default tag value of 1. The Management VLAN is used to
distinguish VLAN traffic flows for the LAN. The trunk port marks the frames with special tags as
they pass between the Altitude 35xx 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 for LAN1 and LAN2.
A trunk port configured with 802.1Q tagging can receive both tagged and untagged traffic. By
default, the access point forwards untagged traffic with the native VLAN configured for the port.
The Native VLAN is VLAN 1 by default. Extreme Networks suggests leaving the Native VLAN set
to 1 as other layer 2 devices also have their Native VLAN set to 1.
10 Use the LAN drop-down menu to map one of the two LANs to the WLAN listed to the left. With
this assignment, the WLAN uses this assigned LAN interface.
11 Select the Dynamic checkboxes (under the Mode column) to configure the VLAN mapping as a
dynamic VLAN.
Using Dynamic VLAN assignments, a VMPS (VLAN Management Policy Server) dynamically assigns
VLAN ports. The Altitude 35xx uses a separate server as a VMPS server. When a frame arrives on
the Altitude 35xx, 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 configured. Otherwise, the
checkbox is disabled.
12 Use the VLAN drop-down menu to select the name of the target VLAN to map to the WLAN listed
on the left-hand side of the screen.
Extreme Networks recommends mapping VLANs strategically in order to keep VLANs tied to the
discipline they most closely match. For example, If WLAN1 is comprised of MUs supporting the
sales area, then WLAN1 should be mapped to sales if a sales VLAN has been already been created.
13 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.

Configuring LAN1 and LAN2 Settings

Both LAN1 and LAN2 have separate sub-screens to configure the DHCP settings used by the LAN1 and
LAN2 interfaces. Within each LAN screen is a button to access a sub-screen to configure advanced
DHCP settings for that LAN. For more information, see
on page 122. Additionally, LAN1 and LAN2 each have separate Type Filter submenu items used to
prevent specific (an potentially unnecessary) frames from being processed, for more information, see
"Setting the Type Filter Configuration" on page
