配置注意事項
-
-
對于整個中心AP,開啟敏捷分布式SFN漫游功能后,所有RU單頻段(2.4G或5G)上支持的同頻漫游終端數(shù)總數(shù)不超過128,單頻段內其它VAP上終端總數(shù)不超過128。
-
開啟敏捷分布式SFN漫游功能后,所有RU需配置在同一信道。在5G頻段開啟敏捷分布式SFN漫游時,需將信道配置在非雷達信道。
-
參與漫游的各個RU需要關聯(lián)在同一中心AP上。不支持跨中心AP的敏捷分布式SFN漫游。
-
-
如果2.4G或5G射頻同時開啟敏捷分布式SFN漫游,則建議使用不同的SSID,否則可能導致STA切換射頻,影響用戶體驗。
-
一個射頻上只能有一個VAP使能敏捷分布式SFN漫游功能。如果一個射頻上配置了多個VAP,建議在沒有配置敏捷分布式SFN漫游的所有VAP上配置VAP限速總和為5Mbps。
如果AP組的某個射頻上有VAP使能了敏捷分布式SFN漫游功能,則在對應中心AP下關聯(lián)到該射頻的所有STA的漫游軌跡均可能會帶有s標記。
-
開啟敏捷分布式SFN漫游功能的射頻上不能再配置信道掃描、信道調優(yōu)和智能漫游。

操作步驟
- 配置周邊設備 # 配置Router的接口GE1/0/0的IP地址,并配置指向STA網(wǎng)段的靜態(tài)路由。

- 配置中心AP與其它網(wǎng)絡設備互通 # 配置中心AP的接口GE0/0/1和GE0/0/2加入VLAN100(管理VLAN),GE0/0/24和GE0/0/25加入VLAN101(業(yè)務VLAN)。

- 配置中心AP作為DHCP服務器為RU和STA分配IP地址 DNS服務器地址請根據(jù)實際需要配置。常用配置方法如下:
- 接口地址池場景,需要在VLANIF接口視圖下執(zhí)行命令dhcp server dns-list?ip-address?&<1-8>。
- 全局地址池場景,需要在IP地址池視圖下執(zhí)行命令dns-list?ip-address?&<1-8>。
