How will Link Aggregation be implemented on a Cisco Wireless LAN Controller?

The correct answer is D. One functional physical port is needed to pass client traffic. 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 `mo

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. guide/b_cg75/ b_cg75_chapter_0100010.html
