Switch Configuration

In order to configure the switch, complete these steps.

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

o Gi 2/0/23

o Gi2/0/24

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

a. Configure the port as a Layer 2 switchport.

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

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)#

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

c. Switch(config-if)#switchport mode access

d. Switch(config-if)#switchport access vlan 100

e.

Switch(config-if)#

f. Configure the port for spanning tree PortFast.

g. Switch(config-if)#spanning-tree portfast

h. %Warning: portfast should only be enabled on ports connected to a single

i. host. Connecting hubs, concentrators, switches, bridges, etc... to this

j. interface when portfast is enabled, can cause temporary bridging loops.

k. Use with CAUTION

l.

m. %Portfast has been configured on GigabitEthernet2/0/23 but will only

n. have effect when the interface is in a non-trunking mode.

Switch(config-if)#

o. Configure the port for EtherChannel with appropriate mode.

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

q.

r. Creating a port-channel interface Port-channel 1

s.

Switch(config-if)#

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

4. Switch(config)#port-channel load-balance ?

5. dst-ip Dst IP Addr

6. dst-mac Dst Mac Addr

7. src-dst-ip Src XOR Dst IP Addr

8. src-dst-mac Src XOR Dst Mac Addr

9. src-ip Src IP Addr

10. src-mac Src Mac Addr

11.

12. Switch(config)#port-channel load-balance src-mac

13.

Switch(config)#

Server Configuration

In order to configure the server, complete these steps:

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.



2. Highlight both NICs, and the click Team.



The NIC team is created.

3. Click Properties.



4. 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.



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



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



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



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



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



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



10. Once the NIC adapters are teamed and a new connection is formed, the individual NIC adapters are disabled and are not accessible through the old IP address. Configure the new connection with static IP address, default gateway, and DNS/WINS settings or for dynamic configuration.

Verify

Use this section to confirm that your configuration works properly.

The Output Interpreter Tool ( registered customers only) (OIT) supports certain show commands. Use the OIT to view an analysis of show command output.
