136 Implementing IBM System Networking 10Gb Ethernet Switches
At the prompt, enter the IPv4 address for the selected default gateway (Example 4-23).
Example 4-23 Default gateway IP
Current IP address: 0.0.0.0
Enter new IP address:
Enter the IPv4 address in dotted decimal notation, or press <Enter> without specifying an
address to accept the current setting.
At the prompt, enter y to enable the default gateway, or n to leave it disabled (Example 4-24).
Example 4-24 Enable default gateway
Enable default gateway? [y/n]
If you answer yes, the system prompts you to configure another default gateway
(Example 4-25).
Example 4-25 Next default gateway configuration
Enter default gateway number: (1-4)
Repeat the steps in this section until all the default gateways are configured, in case you want
to configure more than one. When all default gateways are configured, press <Enter> without
specifying any number. In our lab setup, we specified only one default gateway.
IP routing
When IP interfaces are configured for the various IP subnets attached to your switch, IP
routing between them can be performed entirely within the switch. This setup eliminates the
need to send inter-subnet communication to an external router device. Routing on more
complex networks, where subnets might not have a direct presence on the RackSwitch
G8264, can be accomplished through configuring static routes or by letting the switch learn
routes dynamically.
This part of the setup program prompts you to configure the various routing parameters. At
the prompt, enable or disable forwarding for IP Routing (Example 4-26).
Example 4-26 Enable IP forwarding
Enable IP forwarding? [y/n]
Enter y to enable IP forwarding. To disable IP forwarding, enter n. To keep the current setting,
press Enter.
Final steps
When prompted, decide whether to restart the setup or continue (Example 4-27).
Example 4-27 Restart Setup
Would you like to run from top again? [y/n]
Enter y to restart the Setup utility from the beginning, or n to continue.
