4. Attach a logical network to a physical host network interface by selecting and dragging the logical network into the Assigned Logical Networks area next to the physical host network interface.
   Alternatively, right-click the logical network and select a network interface from the drop-down menu.
5. Configure the logical network:
   1. Hover your cursor over an assigned logical network and click the pencil icon to open the Edit Management Network window.
   2. Select a Boot Protocol from:

      • None,
      • DHCP, or
      • Static.
        If you selected Static, enter the IP, Subnet Mask, and the Gateway.
   3. To configure a network bridge, click the Custom Properties drop-down menu and select bridge_opts. Enter a valid key and value with the following syntax: [key]=[value]. Separate multiple entries with a whitespace character. The following keys are valid, with the values provided as examples. For more information on these parameters, see Section C.1, “Explanation of bridge_opts Parameters”.

      forward_delay=1500 
      gc_timer=3765 
      group_addr=1:80:c2:0:0:0 
      group_fwd_mask=0x0 
      hash_elasticity=4 
      hash_max=512
      hello_time=200 
      hello_timer=70 
      max_age=2000 
      multicast_last_member_count=2 
      multicast_last_member_interval=100 
      multicast_membership_interval=26000 
      multicast_querier=0 
      multicast_querier_interval=25500 
      multicast_query_interval=13000 
      multicast_query_response_interval=1000 
      multicast_query_use_ifaddr=0 
      multicast_router=1 
      multicast_snooping=1 
      multicast_startup_query_count=2 
      multicast_startup_query_interval=3125

   4. If your logical network definition is not synchronized with the network configuration on the host, select the Sync network check box. A logical network cannot be edited or moved to another interface until it is synchronized.

      Note

      Networks are not considered synchronized if they have one of the following conditions:

      • The VM Network is different from the physical host network.
      • The VLAN identifier is different from the physical host network.
      • A Custom MTU is set on the logical network, and is different from the physical host network.
6. Select the Verify connectivity between Host and Engine check box to check network connectivity; this action will only work if the host is in maintenance mode.
7. Select the Save network configuration check box to make the changes persistent when the environment is rebooted.
8. Click OK.

Procedure 7.17. Adding Multiple VLANs to a Network Interface using Logical Networks

1. Use the Hosts resource tab, tree mode, or the search function to find and select in the results list a host associated with the cluster to which your VLAN-tagged logical networks are assigned.
2. Click the Network Interfaces tab in the details pane to list the physical network interfaces attached to the data center.
3. Click Setup Host Networks to open the Setup Host Networks window.
4. Drag your VLAN-tagged logical networks into the Assigned Logical Networks area next to the physical network interface. The physical network interface can have multiple logical networks assigned due to the VLAN tagging.
   ⁠

5. Edit the logical networks by hovering your cursor over an assigned logical network and clicking the pencil icon to open the Edit Network window.
   If your logical network definition is not synchronized with the network configuration on the host, select the Sync network check box.
   Select a Boot Protocol from:

   • None,
   • DHCP, or
   • Static,
     Provide the IP and Subnet Mask.

   Click OK.
6. Select the Verify connectivity between Host and Engine check box to run a network check; this will only work if the host is in maintenance mode.
7. Select the Save network configuration check box
8. Click OK.

Procedure 7.18. Adding Network Labels to Host Network Interfaces

1. Use the Hosts resource tab, tree mode, or the search function to find and select in the results list a host associated with the cluster to which your VLAN-tagged logical networks are assigned.
2. Click the Network Interfaces tab in the details pane to list the physical network interfaces attached to the data center.
3. Click Setup Host Networks to open the Setup Host Networks window.
4. Edit a physical network interface by hovering your cursor over a physical network interface and clicking the pencil icon to open the Edit Interface window.

5. Enter a name for the network label in the Label text field and use the + and - buttons to add or remove additional network labels.
6. Click OK.

Procedure 7.20. Saving a host network configuration

1. Use the Hosts resource tab, tree mode, or the search function to find and select the host in the results list.
2. Click the Network Interfaces tab on the Details pane to list the NICs on the host, their address, and other specifications.
3. Click the Save Network Configuration button.
4. The host network configuration is saved and the following message is displayed on the task bar: "Network changes were saved on host [Hostname]."
