H12-323-V2.0: HCIP-WLAN

Airtime scheduling gives users on the same radio fair channel-occupation time, but it does not take effect between users transmitting different packet types. When WMM is enabled, packets are scheduled by service type, so voice traffic is scheduled with voice traffic and video traffic with video traffic.

In Huawei agile distributed WLANs, RUs and the central AP must reside on the same Layer 2 network so the RUs can discover the central AP. Each RU can discover and therefore associate with only one central AP.

Two-node HSB—both dual-link HSB and VRRP HSB—requires the active and standby WACs to have the same model and software version. Dual-link cold backup and N+1 cold backup permit different WAC models, although their software versions must be the same.

WLAN Planner supports both automatic and manual AP deployment. Manual placement is generally recommended because complex environments require site-specific consideration of obstacles, coverage needs, and installation constraints; automatic placement is appropriate only for simple layouts.

A VLAN that does not yet exist can be added to a VLAN pool. However, the VLAN must subsequently be created before it can take effect. VLAN pools distribute new STAs among multiple service VLANs, reducing the number of STAs in a single VLAN and the broadcast-domain size; hash assignment preferentially retains an STA’s IP address, whereas even assignment generally gives it a different address on repeated connections.
