Using BOOTP to Configure Channel 1 for Processors on Subnets
Configure the BOOTPTAB file according to the subnet mask and
gateway address for each SLC 5/05 processor on the link. See the
example below and the corresponding
BOOTPTAB file on the
next page.
Important: Because BOOTP requests are seen only on the local
subnet, each subnet needs its own BOOTP server and
BOOTPTAB file.
