唐广,配置mesh，移动链路切换配置，同一vlan ping测试不通
组网及说明
问题描述
问题现象：配置mesh，移动链路切换配置，同一vlan ping测试不通；配置完成后，在FAT AP上能看到WLAN mesh链路，但是尝试使用VLAN30 ping测不通（30.1.1.2 ping 30.1.1.1 不通）
过程分析
1、vlan30都有放通
胖ap：
interface WLAN-Mesh1
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 30 40
瘦ap：

2、 瘦ap上也能学习到mac地址

3、 在瘦AP上起一个VLAN30，能够ping通交换机的vlan30地址
解决方法
删除AP视图下的vlan 30，因为在AP视图下配置vlan， 会把标签剥掉，导致FAT AP无法从vlan 30学到arp，而是从vlan 1学到。
