This topic describes how to create a virtual interface for link aggregation. Procedure
1. In the navigation panel, select the system to configure. 2. Select Hardware > Network > Interfaces.
3. In the Interfaces table, disable the physical interface where the virtual interface is to be added by clicking No in the Enabled column.
4. From the Create menu, select Virtual Interface.
5. In the Create Virtual Interface dialog box, specify a virtual interface name in the veth box.
Enter a virtual interface name in the form vethx, where x is a unique ID (typically one or two digits). A typical full virtual interface name with VLAN and IP Alias is
veth56.3999:199. The maximum length of the full name is 15 characters. Special characters are not allowed. Numbers must be between 0 and 4094, inclusively. 6. Select Aggregate from the Bonding Type menu.
Note
Registry settings can be different from the bonding configuration. When interfaces are added to the virtual interface, the information is not sent to the bonding module until the virtual interface is given an IP address and brought up. Until that time the registry and the bonding driver configuration are different.
7. From the General tab, specify the Bonding Mode.
Specify the mode that is compatible with the requirements of the system to which the interfaces are directly attached. Available modes are as follows:
l Round-robin
Transmit packets in sequential order from the first available link through the last in the aggregated group.
l Balanced
Data is sent over interfaces as determined by the hash method selected. This requires the associated interfaces on the switch to be grouped into an Ether channel (trunk) and given a hash via the Load Balance parameter.
l LACP
Link Aggregation Control Protocol is similar to Balanced, except that it has a control protocol that communicates to the other end and coordinates which links within the bond are available to use. LACP provides a kind of heartbeat failover and must be configured at both ends of the link.
8. If you selected Balanced or LACP mode, specify a bonding hash type. From the General tab, select from the Bonding Hash menu.
Options are: XOR-L2, XOR-L2L3, or XOR-L3L4.
XOR-L2 transmits through a bonded interface with an XOR hash of Layer 2 (inbound and outbound MAC addresses).
XOR-L2L3 transmits through a bonded interface with an XOR hash of Layer 2 (inbound and outbound MAC addresses) and Layer 3 (inbound and outbound IP addresses). XOR-L3L4 transmits through a bonded interface with an XOR hash of Layer 3 (inbound and outbound IP addresses) and Layer 4 (inbound and outbound ports).
9. To select an interface to add to the aggregate configuration, select the checkbox that corresponds to the interface, and then click Next.
The Create virtual interface veth_name dialog appears. 10.Enter an IP address, or enter 0 to specify no IP address.
The Internet Protocol (IP) address is the numerical label assigned to the interface. For example, 192.168.10.23.
11.Enter a netmask address.
The netmask is the subnet portion of the IP address that is assigned to the interface. The format is typically 255.255.255.0. If you do not specify a netmask, the system uses the default netmask determined by the TCP/IP address class (A, B, C) you are using.
12.Specify Speed/Duplex options.
The combination of speed and duplex settings define the rate of data transfer through the interface. Select either:
l Autonegotiate Speed/Duplex
Select this option to allow the network interface card to autonegotiate the line speed and duplex setting for an interface.
l Manually configure Speed/Duplex
Select this option to manually set an interface data transfer rate. – Duplex options are half-duplex or full-duplex.
– Speed options listed are limited to the capabilities of the hardware device. Options are 10 Base-T, 100 Base-T, 1000 Base‑T (Gigabit), and 10,000 (10 Gb). – Half-duplex is only available for 10 Base-T and 100 Base-T speeds.
– 1000 and 10000 line speeds require full-duplex. – Optical interfaces require the Autonegotiate option.
– The 10 GbE copper NIC default is 10 Gb. If a copper interface is set to 1000 or 10000 line speed, duplex must be full-duplex.
13.Specify MTU Settings. See About MTU Size Values on page 48. Do the following:
l Click the Default button to return the setting to the default value.
l Ensure that all of your network components support the size set with this option. 14.Optionally, select Dynamic DNS Registration option.
Dynamic DNS (DDNS) is the protocol that allows machines on a network to
communicate with, and register their IP address on, a Domain Name System (DNS) server.
The DDNS must be registered to enable this option. See Registering a DDNS on page 56 for additional information.
15.Click Next.
The Configure Interface Settings summary page appears. The values listed reflect the new system and interface state.
16.Click Finish and OK.
Modifying a Virtual Interface
Procedure
1. In the navigation panel, select the system to configure. 2. Select Hardware > Network > Interfaces.
3. In the Interfaces column, select the interface and disable the virtual interface by clicking No in the Enabled column. Click OK in the warning dialog box.
4. In the Interfaces column, select the interface and click Configure.
5. In the Configure Virtual Interface dialog box, change the settings that are described in the procedures Creating a Virtual Interface for Failover on page 50 or Creating a Virtual Interface for Link Aggregation on page 52.
6. Click Next and Finish.
Configuring a VLAN
Create a new VLAN interface from either a physical interface or a virtual interface. The recommended total number is 80. You can create up to 100 interfaces (minus the number of aliases, physical and virtual interfaces) before the system prevents you from creating any more.
Procedure
1. In the navigation panel, select the system to configure. 2. Select Hardware > Network > Interfaces.
3. In the interfaces table, select the interface to which you want to add the VLAN. The interface you select must have an IP address before you can add a VLAN. 4. Click Create and select the VLAN option.
5. In the Create VLAN dialog box, specify a VLAN ID by entering a number in the ID field. The range of a VLAN ID is between 1 and 4094 inclusive.
6. Enter an IP address, or enter 0 to specify no IP address.
The Internet Protocol (IP) address is the numerical label assigned to the interface. For example, 192.168.10.23.
7. Enter a netmask address.
The netmask is the subnet portion of the IP address that is assigned to the interface. The format is typically 255.255.255.0. If you do not specify a netmask, the selected system uses the default netmask determined by the TCP/IP address class (A, B, or C) you are using.
8. Specify MTU Settings. See About MTU Size Values on page 48.
The VLAN MTU must be less than or equal to the MTU defined for the physical or virtual interface to which it is assigned. If the MTU defined for the supporting physical or virtual interface is reduced below the configured VLAN value, the VLAN value is automatically reduced to match the supporting interface. If the MTU value for the supporting interface is increased above the configured VLAN value, the VLAN value is unchanged.
Do the following:
l Click Default to return the setting to the default value.
l Specify a specific MTU size. DD System Manager does not accept an MTU size that is larger than that defined for the physical or virtual interface to which the VLAN is assigned.
9. Specify Dynamic DNS Registration option.
Dynamic DNS (DDNS) is the protocol that allows machines on a network to
communicate with, and register their IP address on, a Domain Name System (DNS) server.
The DDNS must be registered to enable this option. See Registering a DDNS on page 56 for additional information.
10.Click Next.
The Configure Interface Settings summary page appears. The values listed reflect the new system and interface state.
11.Click Finish and OK.
