Ethernet Support Guide for HP-UX 11i v3

Example 1 Displaying the setting of all parameters for a specific device port
Use the following nwmgr command to display all Ethernet parameters for a specific device port
or function, where ppa is the port or function number.
nwmgr -g -A all -c lanppa
The following is an example of output from the command (for port 2, specified as lan2)
lan2 current values:
Link State = Up
Speed = 1000 Mbps Full Duplex
MTU = 1500
MAC Address = 0xb499ba6499ac
Transmit Flow Control = On
Receive Flow Control = On
Transmit Checksum Offload = On
Receive Checksum Offload = On
Virtual MTU = 32160
TCP Segmentation Offload is now enabled.
TX Interrupt Timer = 48
RX Interrupt Timer = 24
Number of Queues = 8
TCP Packet Reassembly in Driver = On
Example 2 Displaying the setting of a specific parameter on a device port
Use the following command to display information about a specific parameter (parameter) for
a specific Ethernet device port or function (lanppa).
nwmgr -g -A parameter -c lanppa
lan0 current values: Transmit Flow Control = On
For example, to display the speed setting for port lan2, specify the following command:
nwmgr -g -A speed -c lanppa
Sample output:
lan2 current values:
Speed = 1000 Mbps Full Duplex
3.4 Displaying and setting the Ethernet MAC address
Ethernet devices are factory-programmed with a unique Ethernet Station Address. This cannot be
modified. By default, this address is used as the MAC address assigned to the device, but you can
change the address by using the nwmgr or ncweb command.
The default value is ON.
NOTE: Multi-function devices include a unique MAC address for each function configured by
HP-UX.
For information about how MAC addresses are assigned for cards, see the appropriate card
installation guide at the following website:

For information about how MAC addresses are assigned in a blade enclosure, see the HP Virtual
