LU# | This is the Logical Unit number of the LANIC card through which the |
| command is transmitted and from which a response is received. It is a |
| number in the range 2 to 255 (decimal) established during system |
| generation; hence, it always applies to a local LANIC card. See Table 5"1 |
| for default values. |
When a Multicast Address is configured in a card (in RAM), the driver stores a copy in its IFT (Interface Table) extension area. The memory allocated for this use is created during system generation. Three words of memory are required for each Multicast Address.
Note
If there is not enough space in the IFT extension area for the Multicast Addresses, this command will fail with a driver error (DE007, see Appendix A). The default IFT extension size is sufficient for use with HP's networking soft" ware products. If your application accesses the LAN driver directly, you may need to modify the IFT extension size. See the HP 12079A LAN/1000 Link Direct Driver Access Manual product, part number 12079"90001.
Should the card lose its Multicast Addresses, such as on a card reset or powerfail, the driver will rewrite its copy to reconfigure the card.
Note that this command does not add entries in the MCAST.TXT file associated with the card. If a node's MCAST.TXT file requires updating, the HP 1000 editor must be used.
