What are three requirements of enabling a LAG on the WLC? (Choose three.)

Group of answer choices

No more than two interfaces can be in the LAG.

The switch must use channel-group # mode on.

All distributed system interfaces must be added to the LAG.

The WLC must be rebooted

To enable a Link Aggregation Group (LAG) on a Wireless LAN Controller (WLC), the following requirements generally apply:

  1. No more than two interfaces can be in the LAG. - This is often a limitation set by the WLC, especially in scenarios where LAG is used for redundancy and load balancing.

  2. The switch must use channel-group # mode on. - The switch configuration should support LAG, which typically involves configuring the switch ports to use the "mode on" setting to enable port aggregation.

  3. All distributed system interfaces must be added to the LAG. - For proper operation in a distributed environment, it's essential that the relevant interfaces are incorporated into the LAG.

The last option, The WLC must be rebooted, is not generally a requirement for enabling LAG, although it may be needed in some specific setups or configurations, but typically, LAG changes can be applied without needing a reboot.

So the correct answers are:

  • No more than two interfaces can be in the LAG.
  • The switch must use channel-group # mode on.
  • All distributed system interfaces must be added to the LAG.
