Oracle Solaris Administration: IP Services Oracle Solaris 10 1/13 Information An IPMP configuration typically consists of two or more physical interfaces on the . For IPMP configuration tasks, refer to Chapter 31, Administering IPMP (Tasks). Oracle Solaris IPMP involves the following software: You can configure one of the interfaces down to 10 megabits and still place the two interfaces into the. You must have configured all interfaces as members of the IPMP group. role to a user, see Chapter 2, Working With the Solaris Management Console (Tasks).

IPMP requires the ipp fixed network configuration mode resp. Multicast memberships that are associated with Consequently, you must not mark IPv6 link-local addresses as deprecated. Depending on your failure detection requirements, you might need to either use specific types of network interfaces or configure additional IP addresses on each network interface.
Probe-based failure detection involves the sending and receiving of ICMP probe messages that use test addresses. The following two examples show a typical configuration and how that configuration automatically changes when an interface fails. Data Addresses Data addresses are the conventional IPv4 and IPv6 addresses that are assigned to an interface of a NIC at boot time or manually, through the ifconfig command.
In IPv6, link-local addresses are not normally placed in the name service tables.
IPMP Interface Configurations – Oracle Solaris Administration: IP Services
Solaris 11 Administration Information Center unixadminschool. Probe-based failure detection is performed per VLAN-link. Fist i am going to disable eg1 and let see what happens. Interfaces that are configured with IPMP support two types of addresses: For an interface configuratoin use probe-based failure and repair detection, that interface must be configured with at least one test address. Now i am going to enable it back.
The same non-null character string IPMP group name identifies all interfaces in the group.
As a result of load spreading, higher throughput is achieved. The probing rate depends on the failure detection time FDT. If an interface with the same name as another interface that was missing at system boot confiiguration reattached using DR, RCM automatically plumbs the interface.
All requests to detach system components that contain NICs are first checked to ensure that connectivity can be preserved. In such an event, you receive error messages similar to the following moving addresses from failed IPv4 interfaces: These physical interfaces might or might not be on the same NIC.
IPMP Configuration – Solaris 10 vs Solaris 11
If probe-based failure detection is used, the in. The standby interface in an IPMP group is not used for data traffic unless some other interface in the group fails. Network access includes IPv4 unicast, multicast, and broadcast traffic, as well as IPv6 unicast and multicast traffic. You can get information about test address configuration for a physical interface by specifying the logical interface that is assigned to the test address.
Its very clear and simple. A single interface configruation be configured in its own IPMP ipm. Network Interface Card A network interface card is a network adapter that can be built in to the system.
IP network multipathing IPMP provides physical interface failure detection and transparent network access failover for a system with solafis interfaces on the same IP link. You can add new interfaces to an existing group on a live system.
How to configure Solaris 10 IPMP ?
Instead, these failovers might choose an active interface with fewer data addresses that are configured as UP than the standby interface. Internet Key Cnfiguration Overview.
Avoid using spaces in group names. This attachment is often implemented as a device driver and a NIC. Consider the example of four VLANs, bgebgebgeand bge The transmit or receive path of the interface has failed. An active interface is a physical interface that transmits both data traffic and probe traffic.
Introducing IPv6 Overview 4. You can configure one of configuraiton interfaces down to 10 megabits and still place the two interfaces into the same IPMP group. Probe traffic helps to determine the status of the interface and its NIC, including whether an interface has failed. However, some platforms provide other methods. And the result is today’s’ unixadminschool. See Detecting Physical Interface Repairs for more information. No test address configured on interface hme0; disabling probe-based failure detection on it.
After detecting that a NIC has been repaired, IPMP performs failbackthe process cofiguration switching network access back to the repaired interface.
If you want the configuration to be invoked in the current session, do steps 01, 2, and, optionally 3. Suppose you want to create an IPMP group called testgroup1 with the following configuration:. The dynamic reconfiguration DR feature enables you to reconfigure system hardware, such as interfaces, while the system is running.
