Topology

Topologies represent the networks with which the controller and its APs interact. The main configurable attributes of a topology are:

• Name - a string of alphanumeric characters designated by the administrator.
• VLAN ID - the VLAN identifier as specified in the IEEE 802.1Q definition.
• VLAN tagging options.
• Port of presence for the topology on the controller. (This attribute is not required for Routed and Bridged at AP topologies.)
• Interface. This attribute is the IP (L3) address assigned to the controller on the network described by the topology. (Optional.)
• Type. This attribute describes how traffic is forwarded on the topology. Options are:
  • “Physical” - the topology is the native topology of a data plane and it represents the actual Ethernet ports
  • “Management” - the native topology of the controller management port
  • “Routed” - the controller is the routing gateway for the routed topology.
  • “Bridged at Controller” - the user traffic is bridged (in the L2 sense) between wireless clients and the core network infrastructure.
  • “Bridged at AP” - the user traffic is bridged locally at the AP without being redirected to the controller
• Exception Filters. Specifies which traffic has access to the controller from the wireless clients or the infrastructure network.
• Certificates.
• Multicast filters. Defines the multicast groups that are allowed on a specific topology segment.
