input命令
IOS：switch# vlan database
switch(vlan)# vtp domain domain-name
CLI：switch(enable) set vtp [domain domain-name]
12．配置VTP 模式
IOS：switch# vlan database
switch(vlan)# vtp domain domain-name
switch(vlan)# vtp {sever|cilent|transparent}
switch(vlan)# vtp password password
CLI：switch(enable) set vtp [domain domain-name] [mode{ sever|cilent|transparent }][password password]
13．配置VTP版本
IOS：switch# vlan database
switch(vlan)# vtp v2-mode
CLI：switch(enable) set vtp v2 enable
14．启动VTP剪裁
IOS：switch# vlan database
switch(vlan)# vtp pruning
CLI：switch(enable) set vtp pruning enable
15．配置以太信道
IOS：switch(config-if)# port group group-number [distribution {source|destination}]
CLI：switch(enable) set port channel moudle/port-range mode{on|off|desirable|auto}
16．调整根路径成本
IOS：switch(config-if)#spanning-tree [vlan vlan-list] cost cost
CLI：switch(enable)set spantree portcost moudle/port cost
switch(enable)set spantree portvlancost moudle/port [cost cost][vlan-list]
17．调整端口ID
IOS：switch(config-if)#spanning-tree[vlan vlan-list]port-priority port-priority
CLI：switch(enable)set spantree portpri {mldule/port}priority
switch(enable)set spantree portvlanpri {module/port}priority [vlans]
18．修改STP时钟
IOS：switch(config)# spanning-tree [vlan vlan-list] hello-time seconds
switch(config)#spanning-tree [vlan vlan-list] forward-time seconds
switch(config)#spanning-tree [vlan vlan-list] max-age seconds
CLI：switch(enable) set spantree hello interval[vlan]
switch(enable) set spantree fwddelay delay [vlan]
switch(enable) set spantree maxage agingtiame[vlan]
19.启用或禁用Port Fast 特征
IOS：switch(config-if)#spanning-tree portfast
CLI：switch(enable)set spantree portfast {module/port}{enable|disable}
20.启用或禁用UplinkFast 特征
IOS：switch(config)#spanning-tree uplinkfast [max-update-rate pkts-per-second]
CLI：switch(enable)set spantree uplinkfast {enable|disable}[rate update-rate] [all-protocols off|on]
为了将交换机配置成一个集的命令交换机,首先要给管理接口分配一个IP地址,然后使用下列命令:
switch(config)# cluster enable cluster-name
21. 为了从一条中继链路上删除VLAN,可使用下列命令:
switch(enable) clear trunk module/port vlan-range
22. 用show vtp domain 显示管理域的VTP参数.
