Parameter definitions
This section describes the parameters in the
/etc/grdev1.conf
file that are read from
SNMP variables:
Extension Node Identifier
ibmSPDepNodeName
(read-only)
is a 2-digit value that corresponds to the SP Switch Router slot number for the resident SP
Switch Router Adapter card. Valid values are between 00 and 15.
Switch Router Adapter card. Valid values are between 00 and 15.
Node Name
ibmSPDepNodeNumber
is an integer value that is the node number assigned to this card based on its physical
connection to an SP Switch port.
connection to an SP Switch port.
Switch Token
ibmSPDepSwToken
is an octet string size 10 value that internally identifies the SP Switch Router Adapter card’s
connection to the SP Switch network.
connection to the SP Switch network.
When you edit the
grdev1.conf
file, you should consult the SP system administrator to
determine what the Switch Token value should be since the makeup of this field could change
in future releases. For the initial release of SP Switch Router support, the field includes the
switch board number (octets 1–4), switch chip number (octets 5–8), and chip port number
(octets 9 and 10) to which the adapter is connected. The SP system administrator can
determine these values from the SP System Data Repository (SDR) object for the dependent
node.

Switch ARP
ibmSPDepSwARP
is an integer, either 1 or 2. A value of 2, enabled, indicates that ARP is to be used to resolve
network protocol addresses to switch node numbers for the switch network.
network protocol addresses to switch node numbers for the switch network.
A value of 1, disabled, indicates that ARP is not to be used to resolve network protocol
addresses to switch node numbers for the switch network. Instead, the mapping of IP addresses
to switch node numbers is determined via the IP Host Offset.
addresses to switch node numbers for the switch network. Instead, the mapping of IP addresses
to switch node numbers is determined via the IP Host Offset.
Switch Node Number
ibmSPDepSwNodeNumber
is an integer that indicates the physical address or switch node number for the SP Switch
Router Adapter card on the SP switch network (also called the Node Device ID).
Router Adapter card on the SP switch network (also called the Node Device ID).
IP Address
ibmSPDepIPaddr
is the IP address of the card expressed in standard IP notation, x00.00.00.00, and requires the x
prefix to be attached.
prefix to be attached.
Net Mask
ibmSPDepNetMask
is the subnet netmask for the SP Switch Router Adapter card’s IP address expressed in standard
IP notation, x255.255.255.0, and requires the x prefix to be attached. All network bits must be
set to 1, all host bits set to 0.

set to 1, all host bits set to 0.
Max Link Pckt Length
ibmSPDepIPMaxLinkPkt
(read-only)
is the maximum number of bytes carried in the data portion of the IP datagram transmitted on
the SP Switch network, the required setting is 1024.
the SP Switch network, the required setting is 1024.
IP Host Offset
ibmSPDepIPHostOffset
Specified when ARP is disabled, is an integer whose value is the difference between switch
node numbers and the host portion of the corresponding IP addresses. The value to subtract
from the host portion of an IP address to calculate the corresponding switch node number.
node numbers and the host portion of the corresponding IP addresses. The value to subtract
from the host portion of an IP address to calculate the corresponding switch node number.
