On the system with the interfaces to be configured, assume the Primary Administrator role or become superuser. The Primary Administrator role includes the Primary Administrator profile. Determine which interfaces are currently installed on your system. This command reports on all the interface drivers that it finds, regardless of whether the interfaces are currently configured.

Determine which interfaces on the system are currently plumbed. For more information, refer to the ifconfig 1M man page. Example 6—1 Obtaining the Status of an Interface with the dladm command. The next example shows the status display of the dladm command. The output of dladm show-link indicates that four interface drivers are available for the local host. Both the ce and the bge interfaces can be configured for VLANs. The next example shows the status display of the ifconfig -a command. This output shows that only ce0 and bge0 have been plumbed and are ready for use by network traffic.

These interfaces can be used in a VLAN. Because bge0 has been plumbed, you can no longer use this interface in an aggregation. Ensure that the physical interface to be configured has been physically installed onto the system. If you have just installed the interface, perform a reconfiguration boot before proceeding with the next task.

Determine which interfaces are currently installed on the system. Assign an IPv4 address and netmask to the interface. Names such as hostname. Note, too, that a given interface must have only one corresponding hostname file. To prevent these errors, provide an invalid file name to the hostname file that you do not want to use in a given configuration. At a minimum, add the IPv4 address of the interface to the file. You can also add a netmask and other configuration information to the file. Perform a reconfiguration boot. Example 6—2 Adding Persistent Interface Configurations.

The example shows how to configure the interfaces qfe0 and qfe1 to a host.

These interfaces remain persistent across reboots. On the system with the interface to be removed, assume the Primary Administrator role or become superuser. Remove the physical interface. Some applications require every interface on a host to have a unique MAC addresses. For link aggregations, you should use the factory-set MAC addresses of the interfaces in the aggregation configuration.

These interfaces must use their factory-installed MAC addresses. The next procedure shows how to use the eeprom command to check the current value of local-mac-address? Determine whether all interfaces on the system currently use the system-wide MAC address. The value of local-mac-address? You should also change local-mac-address? If necessary, change the value of local-mac-address? Check the MAC addresses of all the interfaces on the system. Look for cases where multiple interfaces have the same MAC address. In this example, all interfaces use the system-wide MAC address Otherwise, go on to the final step.

If necessary, manually configure the remaining interfaces so that all interfaces have unique MAC address. In the example in Step 4, you would need to configure ce0 and ce1 with locally administered MAC addresses. However, any changes made directly with ifconfig are not preserved across reboots. Refer to the ifconfig 1M man page for details.

Basics for Administering Physical Interfaces Network interfaces provide the connection between a system and a network. An Oracle Solaris-based system can have two types of interfaces, physical and logical. Physical interfaces consist of a software driver and a connector into which you connect network media, such as an Ethernet cable. Physical interfaces can be grouped for administrative or availability purposes. Logical interfaces are configured onto existing physical interfaces, usually for adding addresses and creating tunnel endpoints on the physical interfaces.

Most computer systems have at least one physical interface that is built-in by the manufacturer on the main system board. Some systems can also have more than one built-in interface. In addition to built-in interfaces, you can add separately purchased interfaces to a system. A separately purchased interface is known as a network interface card NIC.

Note — NICs are also referred to as network adapters. You must configure at least one interface from the list of interfaces. The first interface to be configured during installation becomes the primary network interface.

Solaris Network Configuration

However, you can configure any additional interfaces during installation or later. Network Interface Names Each physical interface is identified by a unique device name. The variable instance-number can have a value from zero to n, depending on how many interfaces of that driver type are installed on the system. For example, consider a BASE-TX Fast Ethernet interface, which is often used as the primary network interface on both host systems and server systems.

Some typical driver names for this interface are eri, qfe, and hme. When used as the primary network interface, the Fast Ethernet interface has a device name such as eri0 or qfe0. NICs such as eri and hme have only one interface. However, many brands of NICs have multiple interfaces.

For example, the Quad Fast Ethernet qfe card has four interfaces, qfe0 through qfe3. Plumbing an Interface An interface must be plumbed before it can pass traffic between the system and the network. The plumbing process involves associating an interface with a device name. Then, streams are set up so that the interface can be used by the IP protocol. Both physical interfaces and logical interfaces must be plumbed. Interfaces are plumbed either as part of the boot sequence or explicitly, with the appropriate syntax of the ifconfig command.

When you configure an interface during installation, the interface is automatically plumbed. If you decide during installation not to configure the additional interfaces on the system, those interfaces are not plumbed. Some legacy interface types are eri, qfe, and ce. Note — Currently GLDv3 is supported on the following interface types: bge, xge, and eg.

You can create VLANs for local area networks that use switch technology. By assigning groups of users to VLANs, you can improve network administration and security for the entire local network. You can also assign interfaces on the same system to different VLANs. Consider dividing your local network into VLANs if you need to do the following:. Create a logical division of workgroups. For example, suppose all hosts on a floor of a building are connected on one switched-based local network.

You could create a separate VLAN for each workgroup on the floor. Enforce differing security policies for the workgroups. For example, the security needs of a Finance department and an Information Technologies department are quite different. If systems for both departments share the same local network, you could create a separate VLAN for each department.

Then, you could enforce the appropriate security policy on a per-VLAN basis. Split workgroups into manageable broadcast domains. The use of VLANs reduces the size of broadcast domains and improves network efficiency. Each switch manufacturer has different procedures for configuring the ports of a switch. The following figure shows a local area network that has the subnet address Connectivity on LAN The VID on the port must be the same as the VID assigned to the interface that connects to the port, as shown in the following figure. Figure 6—2 shows multiple hosts that are connected to different VLANs.

Two hosts belong to the same VLAN. In this figure, the primary network interfaces of the three hosts connect to Switch 1. The figure also shows that a single host can also belong to more than one VLAN.

SPARC: How to Ensure That the MAC Address of an Interface Is Unique

For a basic example of such a topology, refer to Figure 6—1. On each system, determine which interfaces will be members of a particular VLAN. Determine which interfaces are configured on a system. All interfaces on a system do not necessarily have to be configured on the same VLAN. Note the VID of each interface and the switch port where each interface is connected. Configure each port of the switch with the same VID as the interface to which it is connected. Of the legacy interface types, only the ce interface can become a member of a VLAN.

You can configure interfaces of different types in the same VLAN. Assume the Primary Administrator role, or become superuser. Determine the types of interfaces in use on your system. To create link aggregations for these earlier Oracle Solaris releases, use Sun Trunking, as described in the Sun Trunking 1. Oracle Solaris supports the organization of network interfaces into link aggregations.

A link aggregation consists of several interfaces on a system that are configured together as a single, logical unit.

Link aggregation, also referred to as trunking, is defined in the IEEE The IEEE This link aggregation group is then treated as though it were, in fact, a single link. The following are features of link aggregations:. Increased bandwidth — The capacity of multiple links is combined into one logical link.

Load balancing — Both inbound and outbound traffic is distributed according to user selected load-balancing policies, such as source and destination MAC or IP addresses. Support for redundancy — Two systems can be configured with parallel aggregations. Improved administration — All interfaces are administered as a single unit. Less drain on the network address pool — The entire aggregation can be assigned one IP address.

Link Aggregation Basics The basic link aggregation topology involves a single aggregation that contains a set of physical interfaces. You might use the basic link aggregation in the following situations:. For sites with limited IP address space that nevertheless require large amounts of bandwidth, you need only one IP address for a large aggregation of interfaces.

For sites that need to hide the existence of internal interfaces, the IP address of the aggregation hides its interfaces from external applications. Figure 6—3 shows an aggregation for a server that hosts a popular web site. For security purposes, the existence of the individual interfaces on the server must be hidden from external applications. The solution is the aggregation aggr1 with the IP address This aggregation consists of three interfaces,bge0 through bge2. These interfaces are dedicated to sending out traffic in response to customer queries. The outgoing address on packet traffic from all the interfaces is the IP address of aggr1, Figure 6—3 Basic Link Aggregation Topology.

The figure shows a block for the link aggr1. Three physical interfaces, bge0—bge2, descend from the link block. Figure 6—4 depicts a local network with two systems, and each system has an aggregation configured. The two systems are connected by a switch. If you need to run an aggregation through a switch, that switch must support aggregation technology. This type of configuration is particularly useful for high availability and redundant systems.

In the figure, System A has an aggregation that consists of two interfaces, bge0 and bge1. These interfaces are connected to the switch through aggregated ports.

  • System B has an aggregation of four interfaces, eg0 through eg3. These interfaces are also connected to aggregated ports on the switch. The figure is explained in the preceding context. Back-to-Back Link Aggregations The back-to-back link aggregation topology involves two separate systems that are cabled directly to each other, as shown in the following figure. The systems run parallel aggregations.

    The figure is explained in the following context. In this figure, device bge0 on System A is directly linked to bge0 on System B, and so on. In this way, Systems A and B can support redundancy and high availability, as well as high-speed communications between both systems. Each system also has interface ce0 configured for traffic flow within the local network. The most common application for back-to-back link aggregations is mirrored database servers. Both servers need to be updated together and therefore require significant bandwidth, high-speed traffic flow, and reliability. The most common use of back-to-back link aggregations is in data centers.

    Policies and Load Balancing If you plan to use a link aggregation, consider defining a policy for outgoing traffic. This policy can specify how you want packets to be distributed across the available links of an aggregation, thus establishing load balancing. The following are the possible layer specifiers and their significance for the aggregation policy:. L3 — Determines the outgoing link by hashing the IP L3 header of each packet. Any combination of these policies is also valid.

    The default policy is L4. For more information, refer to the dladm 1M man page. Aggregation Mode and Switches If your aggregation topology involves connection through a switch, you must note whether the switch supports the link aggregation control protocol LACP. However, you can define one of the following modes in which LACP is to operate:. Off mode — The default mode for aggregations. Requirements for Link Aggregations Your link aggregation configuration is bound by the following requirements:.

    You must use the dladm command to configure aggregations. An interface that has been plumbed cannot become a member of an aggregation. Interfaces must be of the GLDv3 type: xge, eg, and bge. All interfaces in the aggregation must run at the same speed and in full-duplex mode. Make sure that the interfaces in your aggregation conform to this requirement. If you are using a switch in your aggregation topology, make sure that you have done the following on the switch:. Configured the ports to be used as an aggregation. The lowest key number is 1. Zeroes are not allowed as keys.

    For example: dladm create-aggr -d bge0 -d bge1 1 Configure and plumb the newly created aggregation. Optional Make the IP configuration of the link aggregation persist across reboots. Enter the IPv4 or IPv6 address of the link aggregation into the file. Example 6—4 Creating a Link Aggregation. This example shows the commands that are used to create a link aggregation with two devices, bge0 and bge1, and the resulting output.

    ProcedureHow to Modify an Aggregation This procedure shows how to make the following changes to an aggregation definition:. Modifying the policy for the aggregation.

    Changing the mode for the aggregation. Modify the aggregation to change the policy. If the switch runs LACP in passive mode, be sure to configure active mode for your aggregation. The values are active, passive, and off. Example 6—5 Modifying a Link Aggregation. This example shows how to modify the policy of aggregation aggr1 to L2 and then turn on active LACP mode. Remove an interface from the aggregation.

    This example shows how to remove the interfaces of the aggregation aggr1. Delete the aggregation. Example 6—7 How to Delete an Aggregation. This example shows how to remove the aggregation aggr1. This section combines configuring VLANs and link aggregations. To create link aggregations, refer to How to Create a Link Aggregation. The key must be in a 3—digit format. VLAN configuration files. In this example, two VLANs are configured on a link aggregation. WordPress Di Responsive Theme. Solaris Networking. Ping ping command can be used to check and display network connectivity.

    To use ping the following five conditions must be met: The interface must be plumbed. Most important options include: snoop Summary output snoop -v Detailed verbose output snoop -V Summary verbose output negation of -v snoop -o filename Redirects the snoop utility output to filename in summary mode snoop -i filename Displays packets that were previously captured in filename snoop -a service To turn on audible clicks for network traffic, for example snoop -a dhcp Note: Press Control-C to stop the snoop utility.

    For more information see Solaris Snoop Packet Sniffer The purpose of this lecture is to give you some understanding of how to set up Solaris network interfaces using the command-line interface. Introduction Sysadmin needs to be able: To use the ifconfig command, To use the ping command, To use the snoop command, Control and monitor the functionality of network interfaces, Display MAC address and IP address, netmask, and routing table Configure interfaces at boot time.
