0x05 Gateway IP

The host can assign Gateway IP addresses the following ways:

• to the main board alone

• to the main board and all modules together

• to individual modules

If the first data byte of the Gateway IP TLV specifies the main board and all modules together (0x05), then the message must have a TLV block for the main board and for each module, specifying their individual IP addresses and subnet masks.

Important! Data byte 0x05 cannot be used in conjunction with 2 module VDAC-ONE or IP Network Interface Series 2 cards. For a two module VDAC-ONE or IP Network Interface Series 2 card, you must assign the gateway address with each individual module IP address.

Used in:

• IP Address Configure message

• IP Address Query message
