Enabling UMC

After UMC is enabled on the MZ510, you can see a maximum of eight vmnics in the ESXi. If FCoE and UMC are enabled at the same time, you can see a maximum of six vmnics and two vmhbas.

On the ESXi System Customization screen, select Configure Management Network and then Network Adapters. The eight ports on the MZ510 are displayed. UMC is enabled and FCoE is disabled so that eight vmnics are displayed. Select the eight vmnics, and press Enter to save the settings and exit. See Figure 5-22.

Figure 5-22 MZ510 physical ports detected in the ESXi after UMC is enabled

Table 5-1 describes the mapping between PFs of the MZ510 and vmnics in the ESXi.

The mapping between PFs of the MZ510 and vmnics varies according to the actual application of NICs. Check the mapping based on the MAC address.

Select IP Configuration, and set an IP address for the management network port (vmnic1 by default).

Select VLAN (Optional), and set a VLAN ID for the management network port, as shown in Figure 5-23. During UMC configuration, a VLAN ID (LPVID) is assigned to each PF. As shown in Figure 5-22, eight vmnics, which belong to the same physical port, are connected. The VLAN ID is the same as the LPVID of PF1 (mapping to vmnic1). In this example, the VLAN ID is VLAN 11, and the management network port is vmnic1.

Figure 5-23 Specifying the VLAN ID of the management network port

After UMC is enabled on the MZ510, the ports on the MZ510 can pass through packets of multiple VLANs. The ports on the peer switch must be configured with the trunk or hybrid mode to pass through packets of multiple VLANs.

On the vSphere Client, click the Configuration tab. On the tab page, click Networking. You can see the eight vmnics associated with vSwitch1, as shown in Figure 5-24. You can choose a vmnic from the eight vmnics when adding a virtual port group.

Figure 5-24 vmnics displayed on the vSphere Client after UMC is enabled

If you do not select all vmnics as the management network on the Network Adapter screen, as shown in Figure 5-25, you can create a vSwitch on the vSphere Client, and associate it with idle vmnics. This is to separate the management network from the service network.

Figure 5-25 Using vmnic0 and vmnic1 for the management network after UMC is enabled

Since the management network uses only vmnic0 and vmnic1, you do not need to specify VLAN(Optional) (leave it blank).

On the vSphere Client, click the Configuration tab. On the tab page displayed, click Networking. In the displayed dialog box, click Add Network, select Create a vSphere standard switch, and then select the vmnics to be associated with, as shown in Figure 5-26.

Click Next. Create a virtual port group for the new vSwitch. Figure 5-27 shows the completed configuration.

On the vSphere Client, select VM_2, and click Configuration. Change the home virtual port group to VM Network3. Then the VM_2 can be associated with six vmnics, as shown in Figure 5-28.

Select VM_3, and click Edit Settings. On the tab page displayed, click Add, select Ethernet Adapter, add network ports for the VM_2, which correspond to vmnic6 to vmnic11, as shown in Figure 5-29.

Log in to the VM_2 OS (SLES 11 SP2), and run the ifconfig command. You can see six ports displayed in the format of eth[num], which correspond to vmnic6 to vmnic11 respectively, as shown in Figure 5-30.
