How Many APs Can an AR Router Manage?

How Many APs Can an AR Router Manage?

An AR router serving as an AC can connect to Fit APs to provide WLAN access for users. The number of APs connected to an AR router depends on the AR router model and whether an AC license is loaded. The following describes the number of APs supported by an AR router in two aspects:
  • Table 29-66 lists the number of APs supported when no AC license is loaded on the AR router.
    Table 29-66  Number of APs supported by an AR router

    AR Model Version

    Number of APs

    V200R005C32 and earlier versions



    By default, the WLAN AC function is unavailable on an AR router, so APs cannot be connected to the AR router. To use the WLAN AC function, apply for and purchase a license from the agent based on the AR model.

    V200R005C32 to versions earlier than V200R007C00SPC900


    V200R007C00SPC900 and later versions



    When serving as an AC, the AR120 and AR500 series allow for access of a maximum of sixteen APs without licenses.

    The AR530 series do not support WLAN AC function.

    The following lists the maximum number of access APs supported on the AR110-S&AR120-S series, AR150-S&AR160-S&AR200-S series, AR1200-S series, AR101-S, AR111EC-S, AR101W-S and AR101GW-Lc-S serving as an AC:
    • AR110-S&AR120-S series, AR101-S, AR111EC-S, AR101W-S and AR101GW-Lc-S: 4
    • AR150-S&AR160-S&AR200-S series: 8
    • AR1200-S series: 12
  • Table 29-67 lists the number of APs supported when an AC license is loaded on the AR router.
