    簡介

    本文件說明如何設定 VLAN 主幹通訊協定 (VTP)。

    必要條件

    需求

    本文件沒有特定需求。

    採用元件

    本文件所述內容不限於特定軟體和硬體版本。

    本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路運作中，請確保您瞭解任何指令可能造成的影響。

    慣例

    如需檔案慣例的詳細資訊，請參閱思科技術提示慣例。

    背景資訊

    VTP減少了交換網路中的管理。若在一台 VTP 伺服器上設定新的 VLAN，會將 VLAN 分配至網域中的所有交換器。這可減少到處設定相同 VLAN 的必要。VTP 是思科專有的通訊協定，適用於大部分的 Cisco Catalyst 系列產品。

    如需VTP的詳細資訊，請參閱瞭解VLAN中繼線通訊協定(VTP)。

    VTP配置指南

    本節提供在網路中配置VTP的一些准則。

    • 除非網路設計要求不同的VTP域，否則所有交換機都具有相同的VTP域名。

      附註：中繼交涉無法在VTP網域間使用。如需詳細資訊，請參閱設定VLAN中繼線通訊協定(VTP)的VTP網域之間封鎖的資料流量一節。

    • VTP域中的所有交換機都必須運行相同的VTP版本。

    • VTP域中的所有交換機都具有相同的VTP口令（如果有）。

    • 所有VTP伺服器交換機都必須具有相同的配置修訂版號，並且還必須是域中的最高配置修訂版。

    • 將交換機的VTP模式從Transparent移到Server時，VTP Transparent交換機上配置的VLAN必須存在於Server交換機上。

    Catalyst交換機上的VTP配置

    本節提供一些基本命令，用於在最常用的Catalyst交換器上設定VTP。

    配置VTP有兩種方法，如本節所示。這些方法的可用性可能與Cisco IOS®軟體的版本不同。例如，方法1在較新版本的Cisco IOS上不可用，另一方面，方法2（全域性配置模式）在舊版軟體中不可用。

    1. 方法1，在VLAN資料庫模式下：

      在Cisco IOS軟體中，可以在VLAN配置模式下配置VTP域名、VTP模式和VLAN。

      1. 在EXEC模式下，發出以下命令以進入VLAN組態模式：

        Switch#vlan database

!--- Issue this command in privileged EXEC mode, 
!--- not in global configuration mode.

Switch(vlan)#

!--- This is VLAN configuration mode.

      2. 發出以下命令以設定VTP域名：

        Switch(vlan)#vtp domain example

      3. 發出以下命令以設定VTP模式：

        Switch(vlan)#vtp {client | server | transparent}

      4. 發出exit命令以退出VLAN配置模式。

        附註：end和Ctrl-Z命令在此模式下無法正常工作。

        Switch(vlan)#end

Switch(vlan)#^Z

% Invalid input detected at '^' marker.

Switch(vlan)#

Swtch(vlan)#exit

APPLY completed.
Exiting....
Switch#

    2. 方法2，在全域性配置模式下：

      在Cisco IOS軟體全域性配置模式下，可以使用Cisco IOS軟體命令配置所有VTP引數。命令格式如下：

      Switch(config)#vtp ?

domain     Set the name of the VTP administrative domain.
file       Configure IFS filesystem file where VTP configuration is stored.
interface  Configure interface as the preferred source for the VTP IP updater
           address. 
mode       Configure VTP device mode
password   Set the password for the VTP administrative domain
pruning    Set the administrative domain to permit pruning
version    Set the administrative domain to VTP version

Switch#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Switch(config)#vtp domain ?
  WORD  The ascii name for the VTP administrative domain.

Switch(config)#vtp domain example
Changing VTP domain name from example to example
Switch(config)#vtp mode server

    3. 發出以下命令以監控VTP操作和狀態：

      Switch#show vtp status 
VTP Version capable             : 1 to 3
VTP version running             : 2

    實用示例

    範例 1：

    此範例包括兩部透過TenGigabitEthernet連結連線的Catalyst 4500交換器：

    1. 交換機A是沒有VTP域名且沒有VLAN的新交換機。交換機C是當前存在的交換機，在VTP域測試中運行時具有16個VLAN。

    2. 在show vtp status命令的輸出示例中，可以看到VTP版本預設為1。交換機A支援VTP V2。但是，在這種情況下，交換機不運行VTP V2。如果使用vtp version 2命令配置了V2版本，則交換機只會運行VTP V2。在本例中，交換機A配置為VTP客戶端。此外，還必須確保所連線的交換機在連線到網路之前其配置修訂版為0，或低於當前VTP伺服器的值：

      Switch-A#show vtp status
VTP Version capable             : 1 to 3
VTP version running             : 1
VTP Domain Name                 : 
VTP Pruning Mode                : Disabled
VTP Traps Generation            : Disabled

    3. 在這個階段，兩台交換機之間手動建立了TRUNK。注意它們如何同步和觀察VTP資料包交換：

Switch-A#debug sw-vlan vtp packets

    4. 交換機C向交換機A傳送總結通告。然後，交換機A從中獲取VTP域名，如以下輸出示例所示：

      !--- On Switch-A:

      *Nov 25 02:45:46.580: VTP LOG RUNTIME: switchport trunk mode on Te3/2 has changed

*Nov 25 02:45:46.580: VTP LOG RUNTIME: delaying first flood on new trunk

      !--- This indicates that Switch-A has received its first summary advertisement.

      !--- This is where Switch-A gets the VTP domain name.

    5. 啟用調試後，您可以看到交換器A收到沒有跟隨者的總結通告。因此，交換機A更新其域名並傳送通告請求以獲取VLAN資訊，如以下示例輸出所示：

      !--- On Switch-A

      *Nov 25 02:45:51.108: VTP LOG RUNTIME: Summary packet rev 4 greater than domain test rev 0

*Nov 25 02:45:51.108: VTP LOG RUNTIME: Domain test currently not in updating state

*Nov 25 02:45:51.108: VTP LOG RUNTIME: Summary packet with followers field zero

*Nov 25 02:45:51.108: VTP LOG RUNTIME: Transmit vtp request, domain test, start value 0


      !--- This is where the advertisement request is sent.

    6. 交換機C向VLAN 1傳送另一個包含欄位跟隨者的彙總通告。包含所有VLAN的子集通告將顯示在此輸出中。然後，交換機A配置所有VLAN:

      !--- On Switch-A:

      *Nov 25 02:45:51.595: VTP LOG RUNTIME: Summary packet received, domain = test, rev = 4, followers = 1, length 80, trunk Te3/2

      !--- Switch-A has received its second summary advertisement.

      !--- This configuration revision is higher than that on Switch-A. 

      *Nov 25 02:45:51.595: VTP LOG RUNTIME: Validate TLVs : #tlvs 1, max blk size 4
