Server Nic multi-nic binding and vlan support

Server Nic multi-nic binding and vlan supported versions: 1.0 principle: Use the 802.3ad protocol to bind multiple NICs. The 802.31p protocol is used to support multiple VLANs. Result: Through the netperf test, the traffic bound to the dual-nic can reach Gbps or above. With vlan support, the server can bind ip addresses of multiple VLANs.

Software environment: broadcom Nic windows 2003 windows 2008 Dotnet3.5 broadcom management software BACSintel Nic windows 2003 windows 2008 latest driver package hp Server latest driver package, hp NIC Management Tool linux centos 6.2 note: www.2cto.com 1) Be sure to determine the relationship between the switch port and the server Nic. 2) during configuration, the switch port is closed. After the server and the switch are all configured, the port is enabled again. Otherwise, the switch port may be blocked automatically. 3) The NIC ip address is lost during configuration. If it is a remote operation, the connection will be lost. Please make a plan. Procedure: 1. vswitch configuration multi Nic binding support for assuming port 3, 4 Do port-channel, the related configuration is as follows: snda-intel-lab-2960s-250 # sh running-config int port-channel 1 Building configuration... current configuration: 55 bytes!

Currently, the management tools that can be downloaded only support windows server 2008, if you need to support windows server 2003, download the old version on the support page of dell IBM and other manufacturers. 3) The hp Server is installed with the latest NIC Driver and management tool. The hp setting method is similar to the broadcom setting. Multi-nic binding introduces the use of the broadcom management tool. Nic vlan describes the use of the hp Nic. Linux system does not need to install special software 3. Configure the NIC port to bind to the Windows system broadcom Nic to add a port group

Next step

Enter a name

Select 802.3ad www.2cto.com

Add the ENI to be bound

Configure vlan. Generally, No. skip this step.

Complete

Several minutes of Configuration

It takes several minutes for the network card to negotiate with the switch. After the network card is finished, you can see that the two network cards are working normally.

Select attributes for an intel Nic

Select group-combine this adapter with other adapters-New Group


Select Nic



 
The Ip address is successfully created and bound to the new group.

For Windows systems, select the network connection attribute for the Intel NIC-nic Configuration

Click vlan

Create a new vlan and enter the vlan id name --- www.2cto.com

After a while, you can see two NICs in the Network Manager,

If you need to create multiple VLANs, you can also set them. The Broadcom Nic uses the hp Server as an example. dell ibm uses the broadcom management tool. The configuration process is similar to selecting the NIC for which the vlan needs to be configured. Click the vlan button.

Add a vlan100


Wait for configuration to take effect

After that, you can see that a network card, vlan100, is generated. If you need to generate multiple VLANs, you can repeat the operation:
