HP-UX System Administrator's Guide: Configuration Management

• Start web-based HP SMH as described in “Starting an HP SMH Web Client”
(page 24). Then:
1. Navigate to Tools→ Network Interfaces Configuration→Network Interface
Cards.
2. Select the NIC tab.
3. Select the LAN interface by clicking the radio button.
The interface details are displayed below the list box.
4. In the right hand actions column, click View/Modify NIC Attributes.
The View/Modify NIC Attributes window is displayed.
5. To use Jumbo Frames with the iether and igelan drivers, set the MTU
value to a number in the range 1501 to 9000 bytes.
The interface will be configured for Jumbo Frame operation, which will be
retained across reboots.
• Verify the MTU change by entering netstat -rn. If the MTU has not changed,
enter the following commands (as root):
# ifconfig lanPPA unplumb
# ifconfig lanPPA ip_addressnetmask netmask up
Verifying that the Networking Driver is in the Kernel
The Gigabit Ethernet drivers updated in December 2006 work on HP-UX 11i v3. To
verify that the driver was loaded in the kernel, execute the following command:
# what /stand/vmunix |grep drivername
where drivername is igelan for the GigEther-01 bundled Gigabit Ethernet or
iether for the IEther-00 bundle.
You should see a response like:
igelan_ilan Version: 1 Dec 18 2006
igelan Revision: B.11.31.05 Dec 18 2006
