Switch Configuration

交换机配置

In order to configure the switch, complete these steps.

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

选择下面的端口创建 etherchannel

Gi 2/0/23
Gi2/0/24

For each of the listed ports, complete these steps:

对列出的端口做一下操作

Configure the port as a Layer 2 switchport.

配置为2层端口

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

在一步只使用在三层交换机上

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)#

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

将接口加入VLAN

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

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)#

Configure the port for EtherChannel with appropriate mode.

配置这个Etherchannle 模式。

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

使用 LACP 主动模式

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

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

配置这个Etherchannle 负载均衡算法。这个配置被应用到交换机上的所有 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

    算法基于源MAC地址
Switch(config)#

Server Configuration

In order to configure the server, complete these steps:

下面一步步完成服务器的配置

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.

打开这个网卡实用程序配置软件。

note ：这个例子中使用的是HP network configuration utility 7。可以通过点击桌面图标或是开始－设置－控制面板－hp network 打开软件。

Highlight both NICs, and the click Team.

高亮选择两块网卡。选择 team

The NIC team is created.

这个NIC 组被创建

Click Properties.

点击属性

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.

这个属性对话框中你要选择etherchannel 所使用的协议类型。

选择 LACP IEEE 802.3ad

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

在下拉对话框中选择一个负载均衡的算法。选择OK。

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

进入这个组属性窗口，点击OK。在程序配置窗口选择 YES 继续

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

这个对话框显示正在处理中

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

提示你需要重启。选择YES

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

重启服务器后打开这个网络配置实用程序查看这个 HP network team 是否状态正常

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

查看网络链接中的本地链接3

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

配置IP地址，自定义网关，DNS/WIN服务器或者选择动态获取

Verify
