ProSafe 20-AP Wireless Controller WC7520 Reference Manual Table 10. IP Settings (Continued) Field Untagged VLAN Description Select this check box if the configured VLAN is untagged. See Untagged VLANs following this table. 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 t 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: The Untagged VLAN check box should be cleared only if the hubs or switches on your LAN support the VLAN (802.1Q) standard. Likewise, the untagged VLAN value should be changed 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.

ProSafe 20-AP Wireless Controller 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 t 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:
The
Untagged VLAN
check box should be cleared only if the hubs
or switches on your LAN support the VLAN (802.1Q) standard.
Likewise, the untagged VLAN value should be changed 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.
Untagged VLAN
Select this check box if the configured VLAN is untagged. See
Untagged VLANs
following this table.
