Configuring a Classical IP over ATM Interface over an ATM Interface
Configuring the ATM Adapter for Classical IP over ATM
Chapter 3 33
Step 6. If an IP interface is already listed in the “Configured Interfaces” list,
highlight the interface and select Modify Interface from the “Actions”
menu. This opens the “Modify IP interface” window.
If no IP interface is listed in the “Configured Interfaces” list, select Add
IP Interface from the “Actions” menu. This opens the “Add IP
interface” window.
NOTE Because you are allowed to create only one Classical IP interface for an
adapter, the Add Interface option does not appear in the “Actions”
menu when an IP interface is already defined.
See the online help for details about the parameters. Also, see Figure 3-3
on page 29 for a sample network.
Step 7. Enter the IP Address and the Subnet Mask of the ATM adapter.
NOTE The IP address must belong to a different subnet than other network
adapters in the same HP 9000 system. It must be unique in your network.
Step 8. Ensure that the MTU Size is not smaller than 576 bytes (as defined in
RFC 1063) or larger than 9180 bytes (the default setting). Note that
these limits are for Classical IP (CIP) interfaces only.
Step 9. Set Node Type to ATM ARP Client.
Step 10. Enter the ATM address of the ATM ARP Server.
Step 11. Select the OK button when you are finished, and verify correct operation
as described in “Verifying That the Classical IP Interface is Operational”
on page 34.
