Management Vlans; Untagged Vlans; Manage The Dhcp Server - NETGEAR ProSafe WC7520 Reference Manual

Management VLANs

Management VLANs are used for all SNMP and HTTP traffic to and from the wireless
controller and managed access points.
For large deployments, NETGEAR recommends that the wireless controller and access
points are in separate VLANs to ensure uninterrupted connectivity between the wireless
controller and the access points.
The wireless controller and access points share heartbeat messages to keep synchronized
and share configurations and client key data to facilitate seamless roaming.

Untagged VLANs

When the Untagged VLAN check box is selected, one VLAN can be configured as an
untagged VLAN:
• When the wireless controller sends frames associated with the untagged VLAN to the
LAN (Ethernet) interface, those frames do not carry an 802.1Q VLAN header.
• When the wireless controller receives untagged traffic from the LAN (Ethernet) interface,
those frames are assigned to the untagged VLAN.
If the Untagged VLAN check box is cleared, the wireless controller tags all outgoing LAN
(Ethernet) frames, and accepts only incoming frames that are tagged with known VLAN IDs.
Note: Clear the Untagged VLAN check box only if the hubs and switches
on your LAN support the VLAN (802.1Q) standard. Likewise, change
the untagged VLAN value only if the hubs and switches on your LAN
support the VLAN (802.1Q) standard.
Changing either of these values will result in a loss of IP connectivity if the hubs and switches
on your network have not yet been configured with the corresponding VLANs.

Manage the DHCP Server

Note: Make sure that a DHCP server is available; otherwise, the Discovery
Wizard does not function correctly. If you already have a DHCP
server on your network, do not enable the DHCP server on the
wireless controller.
The wireless controller can function as a DHCP server. Multiple DHCP server pools can be
added for different VLANs. This screen lets you enable and configure the DHCP server. You
can also add DHCP servers.
