Booting and Installing an Operating System 3-11
3.1.6 ei*0_protocols or ew*0_protocols
The ei*0_protocols or ew*0_protocols environment variable sets net-
work protocols for booting and other functions.
To list the network devices on your system, enter the show device command.
The Ethernet controllers start with the letters “ei” or “ew,” for example, ewa0.
The third letter is the adapter ID for the specific Ethernet controller. Replace
the asterisk (*) with the adapter ID letter when entering the command.
The syntax is:
set ei*0_protocols protocol_value or
set ei*0_protocols protocol_value
The options for protocol_value are:
mop (default) Sets the network protocol to mop (Maintenance Operations
Protocol), the setting typically used with the OpenVMS oper-
ating system.
bootp Sets the network protocol to bootp, the setting typically used
with the Tru64 UNIX operating system.
bootp,mop When both are listed, the system attempts to use the mop
protocol first, regardless of which is listed first. If not suc-
cessful, it then attempts the bootp protocol.
