The ping statistics that are displayed indicate whether the network
connection is working or not.
Linux
To verify that the Ethernet interface is up and running on a Linux platform,
run ifconfig to check the status of the Ethernet interface. In addition, it is
possible to use the netstat -i command to check the statistics on the
Ethernet interface. See “Installing Linux Driver Software” on page 54 for
information on ifconfig and netstat.
Ping an IP host on the network to verify connection has been established.
From the command line, type ping IP address, and then press Enter.
The ping statistics that are displayed indicate whether or not the network
connection is working.
Microsoft
Windows Server
2008 Hyper-V
Microsoft Windows Server 2008 Hyper-V™ is a hypervisor virtualization
system. For information on Hyper-V, see http://www.microsoft.com/
windowsserver2008/en/us/hyperv.aspx.
This section addresses issues that affect the configuration of NetXtreme II
network adapters and teamed adapters when Hyper-V is used.
Note
Ensure that Integrated Services, which is a component of Hyper-V,
is installed in the guest operating system (child partition) for full
functionality.
Single Network
Adapter
When configuring a NetXtreme II network adapter for Hyper-V, be aware
of the following:
 An adapter that is bound to a virtual network should not be configured
for VLAN tagging through the driver's advanced properties. Instead,
Hyper-V should manage VLAN tagging exclusively.
 Since Hyper-V does not support Jumbo Frames, it is recommended
that this feature not be used or connectivity issues may occur with the
child partition.
 The Locally Administered Address (LAA) set by Hyper-V takes
precedence over an address set in the adapter's advanced properties.
 A TOE-enabled network adapter that is bound to a Hyper-V virtual
network reports TOE as an offload capability in BACS; however, TOE
does not work. This is a limitation of Hyper-V because this system
does not support TOE.
 In an IPv6 network, a team that supports Checksum Offload (CO) and
Large Send Offload (LSO) and is bound to a Hyper-V virtual network
reports CO and LSO as an offload capability in BACS. Also, in an IPv6
