A network administrator needs to deploy Link Aggregation (LAG) on a Cisco AireOS Wireless LAN Controller (WLC) connected to an upstream Cisco Catalyst switch. Place the operational steps required to enable and establish the LAG connection in the correct sequential order from first to last.
- 1Enable Link Aggregation (LAG) in the WLC controller configuration settings.
- 2Save the WLC configuration and reboot the wireless controller.
- 3Configure the physical connected ports on the upstream switch into a single EtherChannel group using channel-group mode 'on'.
- 4Verify operational status of the switch Port-Channel and confirm that WLC management and dynamic interface traffic passes across the aggregated bundle.
Cevap
The correct sequential order to deploy LAG on an AireOS WLC is: 1) Enable LAG in WLC settings, 2) Save configuration and reboot the WLC, 3) Configure connected upstream switch ports into an EtherChannel using mode 'on', and 4) Verify operational status of the aggregated bundle.
To successfully deploy LAG on an AireOS Wireless LAN Controller, the feature must first be enabled in WLC global controller settings. Because enabling LAG reorganizes physical ports into a single logical interface, the configuration must be saved and the controller rebooted to take effect. Following the reboot, the upstream Catalyst switch physical ports must be configured into a single EtherChannel using mode 'on' (static aggregation, since AireOS does not negotiate via LACP or PAgP). Finally, the network engineer verifies that the Port-Channel is operational and passing traffic across mapped WLAN VLANs.
