The size of the driver is such that it will fit into a two"page partition. It is recommended that the LANIC card driver be the only driver in a partition.

Table Generation

The •Table Generation" portion of the answer file must contain entries that provide one Interface Table (IFT) and one Device Table (DVT) for each card in the system. Example 3"1 shows the entries required for table generation with two LANIC cards in the system. An IFT command is entered for each card in the following form:

IFT,/RTE_A/%ID*67,SC:sc

where:

 

%ID*67

is the relocatable driver file that also contains IFT default parameters.

 

These defaults include:

 

Entry point = ID.67

 

Interface Type = IT:0, defaulted to zero

 

IFT extension size = TX:73, defaulted to 73

SC:sc

specifies the octal select code of the LANIC card (set by switch SW1).

The IFT extension, specified by TX serves as a table area (driver's class table) for Destination Service Access Points (DSAPs)/Program Codes (PCs)/Ethernet Packet Types (ETs), and associated Class I/O class numbers. In addition, it is used to store a Multicast Address List and other variables used in the driver.

The default IFT extension size is sufficient for use with HP's networking software products. If you will be using other applications that access the LAN driver directly, you may need to modify the IFT extension size. See the HP 12079A LAN/1000 Link Direct Driver Access Manual, part number 12079"90001, for more information.

Although there is no device driver associated with the LANIC card, one DVT must be generated for each card. To set up the device table, DVT commands are used. The commands must immediately follow the IFT command for which they apply, and take the following form:

DVT,,LU:lu,DT:67b,TO:200

where:

 

LU:lu

specifies the unique decimal logical unit number to be assigned to the

 

•pseudo device".

 

Because Node Manager Software uses Extended LU EXEC calls

 

(XLUEX), LUs from 2 to 255 may be assigned.

DT:67b

specifies the device type as 67 octal.

TO:200

specifies timeout for device request completion equal to 2 seconds.
