</strong></p><p>负载均衡的作用就是当企业部署了无线网络,但是客户总是习惯连接第一个SSID,造成该AP繁忙,而周围的AP则非常空闲,这样达不到资源利用最大化,还会导致频繁掉线,更有可能导致AP直接奔溃重启。负载均衡的实现就是AP周期性的上报给AC自己关联的用户数量或者流量承载,AC通过参数来定义新接入的客户端,是否关联到该AP上面,检查到该AP已经超过阀值,则会告诉该AP,拒绝该客户端关联,从而关联其他SSID,或者自动的关联到其他SSID上面,客户感觉不到。</p><p><strong>负载均衡模式分为静态与动态</strong> </p><p>1、静态的话则是认为手工的把需要负载均衡的AP加入到一个组中,然后AC根据负载均衡算法来对这些AP实现负载均衡。</p><p>2、动态的话则是只需要启用即可,客户端在接入AP前,发送广播Probe Request报文扫描周围AP。AP收到STA探测信号后,上报AC。AC将所有上报该客户端的AP动态组成一个组,然后根据负载均衡组算法来决定是否允许客户端接入。</p><p>负载均衡的方法分为基于会话或者基于流量</p><p>1、基于会话的话,则是在定义的阀值上面,通过AC的负载均衡算法来判断该AP是否超过了该阀值,如果超过了,则通知客户端关联另外的AP接入。 2、基于流量的话,则是定义流量阀值,当该AP处理的流量已经超过定义的阀值后,则通知客户端关联另外的AP接入。</p><p>说明:至于使用哪一种根据实际情况来决定,比如AP部署少,则可以使用静态进行配置,如果非常多的话话,则必须部署动态了,因为静态是有许多限制的。</p><p>在我们这个环境中可以使用静态部署,比如在访客厅部署了多台AP,但是不希望出现某一个AP负载过重,而其他AP却没有利用的情况。</p><div

一个负载均衡组内各AP必须工作在同一个频段(例如,2.4G或5G)。 l 一个AP的射频只能加入到一个负载均衡组。如果是多频AP,则相同射频的AP之间 实现负载均衡。也就是说,一个双频AP同时可以加入到两个负载均衡组。 l 同一个负载均衡组内成员(即AP射频)的工作信道必须不同。 l 每个负载均衡组内成员有限,最多支持3个。 l 配置负载均衡时,所有需要配置负载均衡的AP都要配置在同一AP域内,与同一AC上面</p><p>顺便说下动态负载均衡的配置 </p><div class="rno-markdown-code"><div class="rno-markdown-code-toolbar"><div class="rno-markdown-code-toolbar-info"><div

</strong></p><p><strong>关于无线的实现,其实很大一部分都是在AC上面定义,而AP的话,主要是注意几点,一个是是否能够能AC建立CAWAP隧道,这个非常关键,二层的话则在同一网段,同一VLAN即可,而三层的话 则只能通过DHCP Option43实现,而AC的配置,大部分可以重复调用的,只需要理清思路即可,关键就是二层网络的VLAN放行了,需要考虑后是否有漫游存在,需要放行哪些VLAN,比如有线、无线的流量,管理流量等,包括与上行链路连接的。而一些隔离技术可以在AC上面部署,当然也可以在网关上面部署,建议是在AC上面部署,因为可以直接在AP上面干掉流量了,没必要发送到核心层。</strong> <strong>另外建议的是,无线的流量与优先的流量区分开来,可以单独划分多个VLAN,一个给Guest,另外的给内网其他的无线部门,配置是一样的,注意的是交换机的端口放行等问题。</strong></p></div></div></div><div class="mod-content__source"><div class="mod-content__source-inner"><div

\n负载均衡的作用就是当企业部署了无线网络,但是客户总是习惯连接第一个SSID,造成该AP繁忙,而周围的AP则非常空闲,这样达不到资源利用最大化,还会导致频繁掉线,更有可能导致AP直接奔溃重启。负载均衡的实现就是AP周期性的上报给AC自己关联的用户数量或者流量承载,AC通过参数来定义新接入的客户端,是否关联到该AP上面,检查到该AP已经超过阀值,则会告诉该AP,拒绝该客户端关联,从而关联其他SSID,或者自动的关联到其他SSID上面,客户感觉不到。\n负载均衡模式分为静态与动态\n\n1、静态的话则是认为手工的把需要负载均衡的AP加入到一个组中,然后AC根据负载均衡算法来对这些AP实现负载均衡。\n2、动态的话则是只需要启用即可,客户端在接入AP前,发送广播Probe Request报文扫描周围AP。AP收到STA探测信号后,上报AC。AC将所有上报该客户端的AP动态组成一个组,然后根据负载均衡组算法来决定是否允许客户端接入。\n负载均衡的方法分为基于会话或者基于流量\n1、基于会话的话,则是在定义的阀值上面,通过AC的负载均衡算法来判断该AP是否超过了该阀值,如果超过了,则通知客户端关联另外的AP接入。\n2、基于流量的话,则是定义流量阀值,当该AP处理的流量已经超过定义的阀值后,则通知客户端关联另外的AP接入。\n说明:至于使用哪一种根据实际情况来决定,比如AP部署少,则可以使用静态进行配置,如果非常多的话话,则必须部署动态了,因为静态是有许多限制的。\n在我们这个环境中可以使用静态部署,比如在访客厅部署了多台AP,但是不希望出现某一个AP负载过重,而其他AP却没有利用的情况。\n[AC6605]wlan\n[AC6605-wlan-view]load-balance-group

2的用户关联相差大于20%的话,则AC会告诉下面AP,让客户端自动关联到负载较轻的AP上面。\n[AC6605-wlan-load-group-guest]traffic gap\n当然也可以启用基于流量的,相差多少后,自动负载均衡到其他AP上面,可以根据自己具体环境决定。\n静态负载均衡需要注意的地方\n\nl 一个负载均衡组内各AP必须工作在同一个频段(例如,2.4G或5G)。\nl 一个AP的射频只能加入到一个负载均衡组。如果是多频AP,则相同射频的AP之间\n实现负载均衡。也就是说,一个双频AP同时可以加入到两个负载均衡组。\nl 同一个负载均衡组内成员(即AP射频)的工作信道必须不同。\nl 每个负载均衡组内成员有限,最多支持3个。\nl 配置负载均衡时,所有需要配置负载均衡的AP都要配置在同一AP域内,与同一AC上面\n顺便说下动态负载均衡的配置\n\n[AC6605]

\n关于无线的实现,其实很大一部分都是在AC上面定义,而AP的话,主要是注意几点,一个是是否能够能AC建立CAWAP隧道,这个非常关键,二层的话则在同一网段,同一VLAN即可,而三层的话 则只能通过DHCP Option43实现,而AC的配置,大部分可以重复调用的,只需要理清思路即可,关键就是二层网络的VLAN放行了,需要考虑后是否有漫游存在,需要放行哪些VLAN,比如有线、无线的流量,管理流量等,包括与上行链路连接的。而一些隔离技术可以在AC上面部署,当然也可以在网关上面部署,建议是在AC上面部署,因为可以直接在AP上面干掉流量了,没必要发送到核心层。\n另外建议的是,无线的流量与优先的流量区分开来,可以单独划分多个VLAN,一个给Guest,另外的给内网其他的无线部门,配置是一样的,注意的是交换机的端口放行等问题。","showReadNum":130,"sourceDetail":null,"sourceType":99,"status":2,"summary":"\n某公司的网络架构,这样的架构在目前的网络中是在常见的,假设您接收一个这样的网络,应该如何部署,该实战系列,就是一步一步讲解,如何规划、设计、部署这样一个环境,这里会针对不同的情况给出不同的讲解,比如拓扑中有2个ISP,假设客户需求是,想实现主备的效果,又或者是想负载分担。DHCP部署在防火墙上面或者是单独的服务器上面又该如何配置部署。","tagIds":[17484,117,17203,17298,17314],"title":"9、【实战中提升自己】华为
