United States Patent Restart the system or reload the team after doing Hot Plug operations with a team that includes a non-Intel adapter. Not all team types are available on all operating systems and all adapters. For a disconnected link, an indication directed to the previous primary aggregation group is sent showing an IGMP Leave Group message is pending. In the case of a failover scenario, the new team member will be connected to another port or even another network device.

Receive Load Balancing RLB Offers increased network bandwidth by allowing reception over two to eight ports from multiple addresses. This manual also for: Something somewhere in HP drivers or firmware is always glitchy.
Weird HP NIC Teaming problem, and a VERY strange Explorer/taskbar issue – Ars Technica OpenForum
When multiple protocols reside on the same network device, a protocol address is usually assigned to each resident protocol. If failover occurs and the old primary does not maintain a link, then the NTID transmits IGMP joins out the new primary for all multicast addresses in the table, and transmits an IGMP join out the current primary before continuing normal teaming operation intdrmediate When one is upgraded all.
Second, a change is made from an old primary to a new primary, for example by changing TxNodeAddress into the MAC address of the new aggregation.
Various embodiments and aspects of a method for failover of multicast traffic flows in a computer system using Network Interface Controller NIC teaming can be implemented.
I have experienced this problem with both the 3Com and the Juniper hardware so I intsrmediate think the network gear is at fault. Occasionally when we restart a server, when it comes back up it will be in network limbo. Get console access, disable the Team NIC and then re-enable it, and everything is perfectly functional again.
The teaming driver can maintain a list of multicast IP addresses that are received by the driver while receiving a multicast flow. Page 47 – Active Path failover configuration: Packet formatting is defined by a selected transmission protocol.
A teaming driver proactively updates a switched network after failure of a team member to enable multicast teamong to be redirected to teaminh validated receive path for the team. Sun Nov 08, 5: Page 91 – Scenario A Configure team member features similarly or failover and team functionality are affected with possible severe consequences.
You can create a VMLB team with mixed-speed adapters.

Adapter Teaming is that of Layer 2 and Layer 3 addresses, and the way they are handled. Essentially, the MAC addresses are decoupled from the network adapters and pooled together. The method according to claim 18 further comprising: For example, the teaming driver simply chooses the team member located in the lowest numbered slot as the primary member.
The failover techniques disclosed herein extend capabilities of a teaming driver to take IGMP messages into consideration.
The physical adapter buffers or descriptors might need to be increased when set into a team. Page 16 – Using Multi-homing for server network re The teaming drivers operate a teaming mechanism whereby a team of network adapter ports can function as a single virtual adapter. If failover occurs and the old primary maintains a linkthen the NTID transmits an IGMP leave on the old primary for all multicast addresses in the table, transmits IGMP joins out the new primary for all multicast addresses in the table, and transmits an IGMP join out the current primary before continuing normal teaming operation Hp laserjet m mfp series – software technical reference pages.
For example, during monitoring of Internet Group Management Protocol IGMP traffic, a list of joined multicast streams can be maintained based on the monitored traffic.
In an example embodiment, the illustrative failover technique can be implemented by adding to a context data structure. In contrast, the protocol address is assigned to device software. A computer-readable medium is an electronic, magnetic, optical, or other physical device or means that can contain or store a computer program for use by or in connection with a computer-related system, method, process, or procedure.
When the old primary is reconnected, the leave group command will be sent immediately before any failover scenarios occur. In some embodiments, an IGMP cache may be implemented.
Programs can be embodied in a computer-readable medium for use by or in connection with an instruction execution system, device, component, element, or apparatus, such as a system based on a computer or processor, or other system that can fetch instructions from an instruction memory or storage of any appropriate type.
