SVI和VTP排错
一.VTP问题（show run 无法看到）现象：添加或删除VLAN后信息不同步查看： 1.MD5校验
2.配置版本号
3.vlan数目
4.域名
5.password
解决：是VTP域名和口令PASSWORD同步
查看命令：
SW1#show vtp status
VTP Version : 2
Configuration Revision : 4
Maximum VLANs supported locally : 250
Number of existing VLANs : 9
VTP Operating Mode : Server
VTP Domain Name : ccnproutingandswitch
VTP Pruning Mode : Disabled
VTP V2 Mode : Disabled
VTP Traps Generation : Disabled
MD5 digest : 0xCB 0xA2 0xE4 0x45 0x98 0xBE 0x9D 0x10
Configuration last modified by 0.0.0.0 at 3-1-93 00:19:27
Local updater ID is 12.0.0.251 on interface Vl2 (lowest numbered VLAN interface found)
SW1#show vtp password
VTP Password: cisco
二．SVI和VLAN问题（注意：此部分错误show run 无法看到！！！）
现象：SVI接口 down
注意：2950 可以配置多个SVI，但只有一个SVI是UP 其余administrative down
问题：
1.remote-span
查看命令：
showvlan remote-span
注意：如果VTP是 server-client模式则在VTP域内都能查看。
接口shut no shut会报错：05:17:43: %PM-4-INACTIVE: putting Fa0/2 in inactive state because access VLAN is remote SPAN VLAN
查看：SW1#sh vlan remote-span
Remote SPAN VLANs
------------------------------------------------------------------------------
2解决：SW1(config-vlan)#no remote-span
2.vlan suspend
现象：双UP但不能通信
解决： -vlan）state active3.vlan media
现象：现象：双UP但不能通信
解决： SW1(config-vlan)#media Ethernet
SW1#sh vlanVLAN Name Status Ports
