CSMIM2 Installation Guide 3-5
The CSMIM2 must have an Internet (IP) address in its memory before it
can load its operational image across the Ethernet via the IP protocol.
Therefore, you must enter the IP address before booting the CSMIM2
from a UNIX load host. If you do not define an IP address for the
CSMIM2, it will attempt to learn the address using BOOTP or RARP. If
you do not define a subnet mask, the CSMIM2 uses the generic mask for
the specified IP address.
The CSMIM2 tries to boot from a preferred UNIX load host. If you do not
define a preferred load host, the CSMIM2 broadcasts its load request on
the subnet and loads software from the first host that responds.
If the part of the IP address containing the network address differs from
the preferred load or dump host, that host must be reached through a
gateway. The addr command prompts you for this gateway’s IP address.
The CSMIM2 uses the broadcast address parameter when loading a file.
If this parameter contains a specific address (for example,
132.245.6.255), the CSMIM2 uses only that address for broadcast. If the
value is all zeroes (0.0.0.0), the ROM Monitor tries various combinations
of broadcast addresses and subnet or network broadcasts. The CSMIM2
broadcasts its request three times for each possible combination of
broadcast addresses.
You can specify the IP encapsulation type as either ethernet for Ethernet,
or ieee802 for IEEE 802.2/802.3. The default IP encapsulation is
ethernet. Many systems have hardware Ethernet interfaces that are IEEE
802.3 compliant, but very few actually do 802.3 IP packet encapsulation.
NOTE
Do not change this parameter unless you know absolutely that
your Ethernet does 802.2/802.3 IP packet encapsulation. An
incorrect IP encapsulation type prevents your CSMIM2 from
booting.
