Which statement about Link Aggregation when implemented on a Cisco Wireless LAN Controller is true?
- A . To pass client traffic two or more ports must be configured.
- B . The EtherChannel must be configured in “mode active”.
- C . When enabled, the WLC bandwidth drops to 500 Mbps.
- D . One functional physical port is needed to pass client traffic.
Suggested Answer: D
Explanation:
Link aggregation (LAG) is a partial implementation of the 802.3ad port aggregation standard. It bundles all of the controller's distribution system ports into a single 802.3ad port channel.
Restriction for Link aggregation:
- LAG requires the EtherChannel to be configured for `mode on' on both the controller and the Catalyst switch - > Answer B is not correct.
- If the recommended load-balancing method cannot be configured on the Catalyst switch, then configure the LAG connection as a single member link or disable LAG on the controller -> Answer A is not correct while answer D is correct.
