模拟器bug
注意！注意！不要调整模拟器内设备的内存，极易造成设备出bug，比如路由器内存调小后，自己ping自己都不通！
https://zhiliao.h3c.com/questions/dispcont/8085
“配置没问题，端口也up了,也ping不通自己，是因为hcl路由器或交换机的内存不能人为的调小于520M，调成350M就容易出问题”

关闭日志
关闭终端上下线日志分为以下几种情况
（1）通过console的方式登录时
info-center source STAMGR console deny
info-center source WLANAUD console deny
（2）通过telnet的方式登录时
info-center source STAMGR monitor deny
info-center source WLANAUD monitor deny
以上两种情况互不影响。这两种方式只是在总控制台不显示用户上下线的日志信息，但设备的logbuffer里还是记录的，如果想要在logbuffer也不记录日志，需采取以下两种命令关闭：
info-center source STAMGR logbuffer deny
info-center source WLANAUD logbuffer deny
如关闭DHCP日志
info-center source DHCPS logbuffer deny

二层端口模式
参考链接：https://blog.51cto.com/shyln/2087240
a）access端口
发送（从交换机内部往外发送）：
带有vlan tag：删除tag后，发送
不带vlan tag：不可能出现
接收：
带有vlan tag：若该tag等于该access端口的pvid，则可以接收，进入交换机内部
不带vlan tag：添加该access端口的pvid，进入交换机内部
b）trunk端口（允许发送native VLAN数据的时候，可以不加tag）
发送（从交换机内部往外发送）：
带有vlan tag：若tag等于该trunk端口的pvid，则删除tag后发送；否则保留tag直接发送
不带vlan tag：不可能出现
接收：
带有vlan tag：保留该tag，进入交换机内部
不带vlan tag：添加该trunk端口的pvid，进入交换机内部
c）hybrid端口（允许发送多个VLAN数据的时候，可以不加tag）
发送（从交换机内部往外发送）：
带有vlan tag：
是否带tag进行发送，取决于用户配置（用户可以配置tagged list，untagged list）
不带vlan tag：不可能出现
接收：
带有vlan tag：保留该tag，进入交换机内部
不带vlan tag：添加该hybrid端口的pvid，进入交换机内部
模拟傻瓜交换机
思路，创建全部vlan，端口启用untag。

注意！
1、配置前必须移除两路由间连接线
2、全部配置完成后，连线，次路由会自动重启

端口控制
若要阻止vlan1所有telnet访问，则可以在vlan1中设置出站规则
[H3C]acl advanced 3001

[H3C-acl-ipv4-adv-3001]int vlan1
[H3C-Vlan-interface1]packet-filter 3001 outbound若仅要阻止1.5或网段的telnet访问，则可以设置入站规则

IRF堆叠LACP-MAD检测
参考链接：https://blog.csdn.net/qq_45662411/article/details/105983636
开启前，堆叠线断开后两设备都成为master在线，影响网络运行；开启后，LACP-MAD协议会控制在线的成员关闭端口，只保留一个master，防止网络冲突。
IRF设备配置：
[master]int Bridge-Aggregation 2 #创建一个名为2的聚合端口组
[master-Bridge-Aggregation2]link-aggregation mode dynamic #将此端口组的模式改为动态
[master-Bridge-Aggregation2]mad enable #开启mad检测
[master-Bridge-Aggregation2]quit #退出接口视图
[master]int range g1/0/1 g2/0/1 #同时进入这两个接口
[master-if-range]port link-aggregation group 2 #将他们加入到这个接口组2中
下层配置：
[H3C]int Bridge-Aggregation 2 #创建一个名为2的聚合端口组
[H3C-Bridge-Aggregation2]link-aggregation mode dynamic #将此端口组的模式改为动态
[H3C-Bridge-Aggregation2]quit #退出接口视图
[H3C]int range g1/0/1 g1/0/2 #进入到这两个接口
[H3C-if-range]port link-aggregation group 2 #将这两个端口组加入到接口组2中AP三层上线

80：固定值，不用改变；
07：长度字段，其后面所跟数据的字节长度；
00 00：固定值，不用改变；
01：表示后面的IP地址的个数，此处为一个IP地址；

AP接口如果是access，则ap和客户端在同一个VLAN。
AP接口如果是trunk，则可以分别配置VLAN。
