2. Run the System Administration Manager by entering sam.
3. Double-click Networking and Communications.
4. Double-click Network Interface Cards.
5. Highlight the Gigabit Ethernet card and choose Configure from the Actions menu.
6. Fill in the form according to the instructions using the “Network card Configuration
Worksheet” located in Appendix C.
7. Click the OK button to activate the card and then select exit from the File menu
until you exit SAM.
Step 7: Verify the installation
1. Verify that the connector’s Link LED is steadily on (this means the card and driver
are installed successfully).
NOTE On cards that have them, speed LEDs indicate not only speed but also that there is a
LAN connection. The link indication will occur before data activity indication. If the
card and driver have been installed, but there is no LAN connection, all speed LEDs
will be off.
2. Obtain the PPA number and the station address of each card by using the lanscan
command.
3. To verify link-level connectivity with a remote system, enter:
$ linkloop -i PPA_number remote_station_address
4. To verify IP-level connectivity with a remote system, enter:
$ ping Remote_IP_Address
5. Installation is complete when you have successfully run linkloop, ping and
netstat. To configure remote systems, see “Configuring Remote Network
Connectivity Using SAM” on page 31. Do this step only if remote systems have not
been previously configured.
Optional Step: Configure Jumbo Frames Size (Gigabit Ethernet only)
1. Jumbo frames for the gelan and igelan drivers on Hp-UX 11i v1 have an MTU
setting of 9000. For the iether driver on HP-UX 11i v1, the jumbo frames setting is
in the range of 1501-9000 bytes. For all allowable MTU values, refer to the table of
“Allowable MTU Sizes” depending on which Gigabit Ethernet driver and which
HP-UX version you are using.
If you are using Jumbo Ethernet frames, ensure that all end stations on a given
LAN* have the same maximum transmission unit (MTU) setting. However, switch
ports in your LAN can have any MTU setting greater than or equal to the end
station’s MTU. (*Note: here “LAN” means that the end stations do not have any
routers or layer 3 switches in between them.)
2. Obtain the PPA number of the card by entering lanscan.
3. Choose one of two configuration methods that will permanently save your
configuration.
