Configuring Interoperation Between CE Series Switches and Linux Servers Running SUSE11 SP3
Networking Requirements
In Figure 2-9, the Linux server uses SUSE11 SP3, and the Linux server needs to connect to the CE series switch through link aggregation to implement load balancing.
Configuration Roadmap
- Create an Eth-Trunk on the CE series switch and configure the Eth-Trunk to work in static LACP mode to increase the interface bandwidth and reliability.
- Configure dynamic link aggregation for the network adapter group, that is, configure Mode4 (IEEE 802.3ad), to improve the link reliability, increase the interface bandwidth, and implement link load balancing.
Procedure
- Configure an Eth-Trunk and a VLAN on the CE series switch.

- Configure a network adapter group of the server.
- Log in to the server as the root user.
- Access the network adapter binding and network configuration page.
Click Computer and click Network: Wired on the displayed page.
- Before performing network adapter binding, configure No Link and IP Setup (Bonding Slaves) for the network adapters to be bound.
On the Overview tab page of the Network Settings page, select names of network adapters to be bound and click Edit. The Network Card Setup page is displayed.
On the Network Card Setup page, select No Link and IP Setup (Bonding Slaves) and click Next to access the Network Settings page.
- Create network adapter binding and configure the name for network adapter binding.
On the Network Settings page, click Add to create network adapter binding. Access the Hardware Dialo page.
On the Hardware Dialog page, set Device Type to Bond and configure the name for network adapter binding. Here, the name is set to 0. Click Next to access the Network Card Setup page.
- Configure network parameters of network adapter binding, including the IP address and subnet mask.
On the Address tab page of the Network Card Setup page, enter the IP address and subnet mask of the bound network adapter. For example, the IP address of bond0 is set to 192.168.14.208 and the subnet mask is set to 255.255.255.0.
Click Bond Slaves.
Click Yes in the dialog box that is displayed.
- Select the network adapter to be bound and configure the binding mode.
In Bond Slaves, select the network adapter to be bound.
In Bond Driver Options, click
and select the binding mode.
In the figure, miimon indicates how long a link is checked, in milliseconds. The value 100 indicates 100 ms, that is, 0.1s. That is, when one link is terminated, the backup link is used within 0.1s.
Click Next to access the Network Settings page.
- Add the default route so that bond0 can communicate.
On the Network Settings page, click Routing.
On the Routing tab page, enter the gateway address of the bound network adapter. Click OK.
- Confirm the configuration of the bound network adapter.
On the Network Settings page, select bond0 to check details.
- Save the configuration of the bound network adapter to make the configuration take effect.
Click OK.
Save the configurations automatically.
- Log in to the server as the root user.
and select the binding mode.
Verifying the configuration
- Run the display eth-trunk [ trunk-id ] command in any view to check the Eth-Trunk status. Determine the Eth-Trunk status based on key information in Table 2-17.
