Switch Configuration

交換機配置

In order to configure the switch, complete these steps.

1. Per the Network Diagram, choose the ports to be grouped:

        選擇下面的端口創建 etherchannel

• Gi 2/0/23
• Gi2/0/24

1. For each of the listed ports, complete these steps:

            對列出的端口做一下操作

1. Configure the port as a Layer 2 switchport.

             配置爲2層端口

Note: This step is required only for switches that support both Layer 2 switchports and Layer 3 interfaces.

 

             在一步只使用在三層交換機上

Switch#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Switch(config)#int Gi2/0/23

Switch(config-if)#switchport
Switch(config-if)#

1. Configure the port as an access port and assign the appropriate VLAN.

              將接口加入VLAN

Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 100

Switch(config-if)#

1. Configure the port for spanning tree PortFast.

              配置portfast

Switch(config-if)#spanning-tree portfast
%Warning: portfast should only be enabled on ports connected to a single
 host. Connecting hubs, concentrators, switches, bridges, etc... to this
 interface  when portfast is enabled, can cause temporary bridging loops.
 Use with CAUTION
%Portfast has been configured on GigabitEthernet2/0/23 but will only
 have effect when the interface is in a non-trunking mode.
Switch(config-if)#

1. Configure the port for EtherChannel with appropriate mode.

                     配置這個Etherchannle 模式。

Switch(config-if)#channel-group 1 mode active

使用 LACP 主動模式

Creating a port-channel interface Port-channel 1
Switch(config-if)#

1. Configure the EtherChannel load balancing. This configuration is applicable for all EtherChannels configured on this switch.

            配置這個Etherchannle 負載均衡算法。這個配置被應用到交換機上的所有    etherchannle 。

Switch(config)#port-channel load-balance ?
  dst-ip       Dst IP Addr
  dst-mac      Dst Mac Addr
  src-dst-ip   Src XOR Dst IP Addr
  src-dst-mac  Src XOR Dst Mac Addr
  src-ip       Src IP Addr
  src-mac      Src Mac Addr
Switch(config)#port-channel load-balance src-mac

      算法基於源MAC地址
Switch(config)#

Server Configuration

In order to configure the server, complete these steps:

 

下面一步步完成服務器的配置

1. Start the NIC configuration utility.
   Note: This examples uses the HP Network Configuration Utility 7. In order to use the HP Network Configuration Utility, locate the icon in the Windows 2000 system tray or click Start > Settings > Control Panel > HP Network.

打開這個 網卡實用程序配置軟件。

 

note ：這個例子中使用的是HP network configuration utility 7。  可以通過點擊桌面圖標或是開始  －設置 －控制面板 －hp network  打開軟件。

1. Highlight both NICs, and the click Team.

高亮選擇兩塊網卡。選擇 team

The NIC team is created.

 

這個NIC 組被創建

1. Click Properties.

點擊屬性

1. In the Team Properties windows, choose the appropriate Team Type Selection.
   Note: Since this example configured the switch with LACP, choose the option with IEEE 802.3ad.

這個屬性對話框中你要選擇etherchannel 所使用的協議類型。

 

  選擇 LACP  IEEE 802.3ad

1. Choose the required method from the Transmit Load Balancing Method drop-down list, and click OK.

在下拉對話框中選擇一個負載均衡的算法。選擇OK。

1. In the Team Properties window, click OK, and when the confirmation window appears, click Yes to continue.

進入這個組屬性窗口，點擊OK。 在程序配置窗口選擇 YES 繼續

A dialog box appears that displays the status of the process.

這個對話框顯示正在處理中

1. When you are prompted to reboot the server, click Yes.

      提示你需要重啓。選擇YES

1. Once the server is rebooted, open the network configuration utility in order to verify the teaming status.

重啓服務器後打開這個 網絡配置實用程序 查看這個 HP network team 是否狀態正常

1. Right-click My Network Places. An additional network card, Local Area Connection 3, displays in the window.

             查看網絡鏈接 中的 本地鏈接3

1. Configure the connection with static IP address, default gateway, and DNS/WINS settings or for dynamic configuration.

            配置IP地址，自定義網關，DNS/WIN服務器或者選擇動態獲取
