108CHAPTER 8: CONFIGURING BRIDGING AND ROUTING

Assigning Addresses If the network administrator at a central site has configured the BOOTP Automatically from server so that your SuperStack II bridge/router is a BOOTP client, then

BOOTP Servers Internet addresses may have automatically been assigned during the automatic startup process. In this case, no action on your part is required. If you are responsible for configuring the boot configuration file on the BOOTP server so that automatic startup can take place, see Using Enterprise OS Software.

To verify whether an Internet address was assigned during the automatic startup process, enter:

SHow -IP NETaddr

If an Internet address is shown, then the SuperStack II bridge/router has been assigned that address. If an address was not assigned, the following message is displayed:

No IP address configured

For more information, or if you are unsure if an Internet address has been assigned, contact the network administrator at the central site or your network supplier.

Internet addresses are assigned for individual ports. To verify whether an Internet address was assigned to an individual port, use:

SHow !<port> -IP NETaddr

When the bridge/router is installed for the first time, BOOTP requests are sent from each connected port requesting a BOOTP server to provide the SuperStack II bridge/router port with its Internet address and other configuration information. The ports continue to send BOOTP requests until the request has been answered. Also, every time a path comes up, if no Internet address has been previously assigned to it, BOOTP requests are sent requesting a BOOTP server to provide an Internet address.

After your bridge/router has been installed for the first time, you can control how it handles BOOTP requests using parameters in the BOOTPC Service. For information on this service, see Reference for Enterprise OS Software.
