Cisco Catalyst 2950 系列交換機(jī)2臺(tái)，型號(hào)不限；2. 交叉線序網(wǎng)線1條；3. 1臺(tái)帶有超級(jí)終端程序的PC機(jī)，以及Console電纜及轉(zhuǎn)換器。三、 拓?fù)浣Y(jié)構(gòu)及配置說明圖 8-1 網(wǎng)絡(luò)拓?fù)鋱D如圖所示用交叉網(wǎng)線把C2950A的FastEther

2、net0/24端和C2950B的FastEthernet0/24端口連接起來(lái)。四、 實(shí)驗(yàn)步驟及要求1. 在2950系列交換機(jī)上配置VTP和VLAN的方法有兩種，本實(shí)驗(yàn)演示的是使用vlandatabase命令的一種;另一種是在全局配置模式下發(fā)出配置命令，格式與vlan database方式相似。方法如下：1) vlan vlan-id 輸入一個(gè)VLAN號(hào), 然后進(jìn)入vlan配置狀態(tài)，可以輸入一個(gè)新的VLAN號(hào)或舊的來(lái)進(jìn)行修改。2) name vlan-name (可選)輸入一個(gè)VLAN名，如果沒有配置VLAN名，缺省的名字是VLAN號(hào)前面用0填滿的4位數(shù)，如VLAN0004是VLAN4的缺省名字

3、.2. 首先使用vlan database命令進(jìn)入VLAN配置模式。在VLAN配置模式下，可以設(shè)置VTP的一系列屬性，如vtp?命令所示，也可以對(duì)VLAN進(jìn)行定義。3. 把C2950A交換機(jī)設(shè)置成VTP Server模式(缺省配置)，VTP域名為Test。4. 定義V10、V11、V12和V13等4個(gè)VLAN。5. show vtp status命令顯示了VTP相關(guān)的配置和狀態(tài)信息，我們應(yīng)主要關(guān)注VTP模式、域名，VLAN數(shù)量等信息。6. show vtp counters命令列出了VTP的統(tǒng)計(jì)信息，表明各種VTP相關(guān)包的收發(fā)情況，因?yàn)镃2950A交換機(jī)與C2950B交換機(jī)沒有進(jìn)行VTP信息的

4、傳輸，所以各項(xiàng)數(shù)值均為0。7. 在接口配置模式下的switchport mode access命令設(shè)置對(duì)應(yīng)端口為靜態(tài)VLAN訪問模式。8. 在接口配置模式下的switchport access vlan命令把端口分配給相應(yīng)的VLAN。9. 在第2段中，配置了C2950B交換機(jī)的VTP屬性，域名設(shè)為Test，模式為Client。10. 第3段設(shè)置了C2950A和C2950B之間的VLAN Trunk。所使用的命令是在接口配置模式下發(fā)出switchport mode trunk。當(dāng)然這是命令的一種形式，設(shè)置Trunk還有其他可選的命令形式。11. show interface fa0/24 swi

5、tchport查看了Fa0/24端口上的交換端口屬性，我們關(guān)心的是幾個(gè)與Trunk相關(guān)的信息。它們是:運(yùn)行方式為Trunk、Trunk，封裝格式為802.1Q、Trunk中允許所有VLAN傳輸?shù)取?2. 完成兩臺(tái)交換機(jī)之間的Trunk配置后，可以看到C2950B交換機(jī)上的VTP和VLAN屬性已經(jīng)可以從C2950A交換機(jī)自動(dòng)獲得。13. 最后發(fā)出的ping指令表明C2950A和C2950B之間在IP層是連通的，并且再次驗(yàn)證了Trunk的工作是正常的。五、 實(shí)驗(yàn)結(jié)果第一段 配置2950A交換機(jī)的VTP CLI session with the switch is open.
