1. 第 17 讲 VLAN 和 VTP

8. VLAN 的成员模式 VLAN5 静态 VLAN 动态 VLAN MAC = 1111.1111.1111 主干连接 VLAN 成员策略服务器 1111.1111.1111 = vlan 10 VLAN10 端口 e0/9 端口 e0/4

13. 802.1Q Trunking

14. 802.1Q Frame

16. 确认一个 VLAN Catalyst 2950 wg_sw_2950#show vlan [id vlan# ]

17. 确认一个 VLAN wg_sw_a#sh vlan 9 VLAN Name Status Ports ------------------------------------------------- 9 switchlab2 Enabled ------------------------------------------------- VLAN Type SAID MTU Parent RingNo BridgeNo Stp Trans1 Trans2 ------------------------------------------------------------------------------------------------------- 9 Ethernet 100009 1500 0 1 1 Unkn 0 0 -------------------------------------------------------------------------------------------------------- wg_sw_a#show vlan [ vlan# ]

18. Verifying VLAN Membership on a Catalyst 2950 wg_sw_2950#show vlan brief VLAN Name Status Ports ---- ------------------------ --------- ----------------------- 1 default active Fa0/4, Fa0/5, Fa0/6, Fa0/7, Fa0/8, Fa0/9, Fa0/10, Fa0/11, Fa0/12, Fa0/13, Fa0/14, Fa0/15, Fa0/16, Fa0/17, Fa0/18, Fa0/19, Fa0/20, Fa0/21 5 VLAN5 active Fa0/3 9 VLAN9 active Fa0/22, Fa0/23 1002 fddi-default active 1003 token-ring-default active 1004 fddinet-default active 1005 trnet-default active wg_sw_2950#show vlan brief

19. 修改一个 VLAN 的名称 vlan vlan# name vlan-name wg_sw_a#conf terminal Enter configuration commands, one per line. End with CNTL/Z wg_sw_a(config)#vlan 9 name switchlab90 wg_sw_a#show vlan 9 VLAN Name Status Ports ------------------------------------------------ 9 switchlab90 Enabled ------------------------------------------------ wg_sw_a(config)#

30. 创建 VTP 域 vtp [server | transparent|client] [domain domain-name ] [password password ] [pruning {enable | disable} wg_sw_a(vlan)#

31. Creating a VTP Domain Catalyst 2950 wg_sw_2950#vlan database wg_sw_2950(vlan)#vtp [ server | client | transparent ] wg_sw_2950(vlan)#vtp domain domain-name wg_sw_2950(vlan)#vtp password password wg_sw_2950(vlan)#vtp pruning wg_sw_2950(vlan)#exit Sw(config)#vtp domaian ccna Sw(config)#vtp mode server|client|transparents Sw(config)#vtp domaian ccna Sw(config)#vtp password cisco Sw(config)#vtp pruning

32. 确认 VTP 配置 wg_sw_a#show vtp status

33. 检查 VTP wg_sw_2950#show vtp status wg_sw_ 2950#show vtp status VTP Version : 2 <--- Indicates v2-capable Configuration Revision : 4 Maximum VLANs supported locally : 68 Number of existing VLANs : 6 VTP Operating Mode : Server VTP Domain Name : switchlab VTP Pruning Mode : Enabled VTP V2 Mode : Disabled <--- Indicates v2 disabled; v1 set VTP Traps Generation : Disabled <--- Catalyst 2950 default MD5 digest : 0x3D 0x02 0xD4 0x3A 0xC4 0x46 0xA1 0x03 Configuration last modified by 10.1.1.40 at 5-4-02 22:25:

36. 确认主干功能 wg_sw_a#show trunk

37. 分配交换机 1900 的端口到 VLAN 中 vlan-membership {static { vlan# } | dynamic} wg_sw_a(config-if)#

38. 分配交换机 1900 的端口到 VLAN 中 wg_sw_a#conf terminal Enter configuration commands, one per line. End with CNTL/Z wg_sw_a(config)#interface ethernet 0/8 wg_sw_a(config-if)#vlan-membership static 9 vlan-membership {static { vlan# } | dynamic} wg_sw_a(config-if)#

40. 不同 VLAN 间主机的通信－ ISL 封装 VLAN 3 VLAN 2 ISL interface fastethernet 0/0 no ip address ! interface fastethernet 0/0.1 ip address 10.1.1.1 255.255.255.0 encapsulation isl 3 interface fastethernet 0/0.2 ip address 10.2.2.1 255.255.255.0 encapsulation isl 2 Fast E0/0 10.1.1.2 10.2.2.2
