When implementing Link Aggregation (LAG) between a Cisco Wireless LAN Controller and an upstream switch, specific configuration rules apply to the physical interfaces and channel grouping. Which two statements describe valid operational characteristics or configuration requirements for this LAG deployment? (Select TWO.)
- Every physical distribution port on the wireless controller is combined into one single logical interface.Answer
- The switch ports attached to the controller must be statically bundled into an EtherChannel using mode 'on'.Answer
- CThe switch ports attached to the controller must dynamically negotiate the link using LACP active mode.
- DMultiple distinct LAG groups can be created on a single controller to isolate different wireless VLANs.
Answer
Enabling LAG on a Wireless LAN Controller bundles all physical distribution system ports into a single logical interface, and the connected switch ports must be statically configured in EtherChannel mode 'on'.
Enabling Link Aggregation (LAG) on a Cisco Wireless LAN Controller aggregates all physical distribution system ports into a single logical EtherChannel. Because the controller does not participate in dynamic negotiation protocols like LACP or PAgP, the corresponding switch ports must be statically configured using EtherChannel mode 'on'.
