Hostapd2.11解析笔记_hostapdconf_MLO相关

本文链接：https://blog.youkuaiyun.com/Mr_liu_666/article/details/144826855

最近在调试Hostapd,尝试通过配置使能一个支持MLO的AP,不过不知道hostapd conf里面哪些选项开启后可以使能,所以对Hostapd做一个整体解析.

IEEE 802.11be相关配置

ieee80211be

是否启用 IEEE 802.11be (EHT)

disable_11be

布尔值 (0/1) 用于禁用特定 BSS 的 EHT

eht_su_beamformer

EHT 单用户波束形成器支持

eht_su_beamformee

EHT单用户beamformee支持

eht_mu_beamformer

EHT 多用户波束形成器支持

EHT操作通道信息

有关详细信息，请参阅匹配的 he_* 参数。字段eht_oper_centr_freq_seg0_idx字段用于指示40、80和160 MHz带宽操作的中心频率。在 6 GHz 频段中，eht_oper_chwidth 被忽略，信道宽度源自配置的operating classes（IEEE P802.11be/D1.5，附件 E.1 - 国家信息和操作类别）。

Operating class	Nonglobal operating class(es)	Channel starting frequency (GHz)	Channel spacing (MHz)	Channel set	Channel center frequency index	Behavior limits set
137		5.950	320		31, 63, 95, 127, 159, 191
1378–179		Reserved	Reserved		Reserved	Reserved

eht_default_pe_duration

EHT TB PPDU 中 PE 字段的持续时间.

PE Duration的设置对于网络中的设备能够正确接收和解码数据非常重要。它通常是根据网络环境和需求进行调整的。较短的传输时间可以提高网络的吞吐量和响应速度，但可能会增加干扰和碰撞的可能性。较长的传输时间可以减少干扰和碰撞，但可能会降低网络的吞吐量。

每个HE PPDU（物理层协议数据单元）的传输时间。它用于协调不同设备之间的传输时间，以确保传输的顺序和时机的一致性。

eht_bw320_offset

用于自动信道选择 (ACS)，以指示 EHT 模式下的首选 320 MHz 信道化。如果信道确定或者带宽不是320MHz，则该选项没有意义。

禁用的子通道位图

IEEE P802.11be/3.0，图9-1002c (EHT Operation Information字段格式)。每个比特对应一个20mhz的信道，最低的比特对应最低的频率。位设置为1表示通道被穿刺(禁用)。缺省值为0，表示所有通道都激活。

自动信道选择 (ACS) 中的前导码穿孔阈值。

该值指示理想信道平均干扰因子的百分比，高于该百分比时应对信道进行穿孔。默认值为 0，表示 ACS 算法不应击穿任何通道。

AP MLD

此 AP 是否是 AP MLD 的一部分

AP MLD MAC 地址

配置的地址将被设置为接口硬件地址并用作AP MLD MAC 地址。如果不设置，则当前接口硬件地址将用作 AP MLD MAC 地址。

看起来应该启动3个Hostapd，把mac地址设置为同一个。
