 ProSAFE Wireless Controller
The wireless controller and access points share heartbeat messages to keep synchronized 
and share configurations and client key data to facilitate seamless roaming.
Untagged VLAN Concepts
When the Untagged VLAN check box is selected on the IP Settings page, 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 you clear the Untagged VLAN check box, 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 results in a loss of IP connectivity if the hubs and switches 
on your network are not configured with the corresponding VLANs.
Controller Link Aggregation Concepts
Note:
Link aggregation is not supported on model WC7500 and model 
WC7600v2.
If you connect the two 10GE connections of the wireless controller to a switch or router, the 
wireless controller supports dynamic link aggregation (802.3ad), which you can use either to 
increase bandwidth or to support link redundancy. 
You can enable the wireless controller to automatically create a single link aggregation group 
(LAG) in which the two links share the same speed and duplex settings. The link selection for 
egress traffic is based on the transmit hash policy.
You can also configure a standby link in which only one link in the LAG is active. The standby 
link becomes active only if the active link fails. In such a situation, a failover occurs from the 
failed active link to the standby link, which becomes the new active link.
