Network

The NIC Management Agents display all logical HP Network Interface Controllers (NICs) that are configured on the system you are viewing. The following items can appear in the Network section of the navigation frame:

» Virtual NIC

» Single NIC

» Team(s) of NICs

Virtual NIC

The Virtual NIC is the TCP/IP Loopback interface. It is provided by the Operating System to allow a computer to send packets to itself. A packet is the fundamental unit of transmission on the physical network.

Select the Virtual NIC to view detailed Interface Information (NIC Subsystem - NIC Interface Information).

Single NIC

A single NIC is composed of one physical adapter. Select a single NIC from the list to view more information about that NIC. The information displayed may vary depending on the type of NIC. For example, Ethernet Statistics display for Ethernet adapters.

The following types of information are available depending on the type of NIC:

Controller Information ( NIC Subsystem - NIC Controller Information).
Interface Information ( NIC Subsystem - NIC Interface Information)
Ethernet Statistics ( NIC Subsystem - Ethernet Statistics)
Token Ring Statistics ( NIC Subsystem - Token Ring Statistics)

Team(s) of NICs

A team of NICs is composed of two or more physical adapters that present a single, logical interface on the network. Select a NIC team from the navigation frame to view detailed information about that team. The Logical Adapter Information displays by default. You can also select one of the physical adapters in the team to display additional information about that adapter.

There are three kinds of NIC teams:

Network Fault Tolerant Team
The logical adapter has two or more physical adapters associated with it. One physical adapter is active on the network, and the other physical adapters are hot standbys.
Transmit Load Balancing Team
The logical adapter has more than one physical adapter associated with it. One physical adapter transmits and receives data, while the others only transmit. If the receiving adapter fails, one of the other adapters assumes this role.
Switch-assisted Load Balancing
The logical adapter has more than one physical adapter associated with it. All physical adapters can receive and transmit data. This requires a switch that cooperates with the adapters. If any adapter fails, the load is spread among the remaining adapters.
