A sample init file (ahb.dat) is shown next:

[SLOT 4]

The bridge entry fields (separated by spaces) are:

• Field 1 = host IP address (dotted-decimal)

• Field 2 = host subnet mask (dotted-decimal)

• Field 3 = ATM circuit number (decimal)

• Field 4 = PVC VPI/VCI (decimal, VPI in bits 0-11, VCI in bits 12-23)

• Field 5 = reference VPI/VCI (decimal)

• Field 6 = host flags (decimal, bit field)

• Field 7 = bridge header (hex, 1483 SNAP/LLC + ethernet header)

The host flag bits which can be configured are:

• Bit 0 = no protocol address, do not add bridge entry to table

• Bit 3 = add new PVC (VPI/VCI in field 4) based on reference PVC

• Bit 4 = do not forward packets that match this IP address

• Bit 7 = if set, indicates that host entry should be deleted

The bridge header has the following format:

• Octets 00-09 = encapsulate for 1483 bridged Ethernet packet

• Octets 10-15 = destination MAC address

• Octets 16-21 = source MAC address

• Octets 22-23 = protocol ID (0x800 for IP)

The reference VPI/VCI identify a preconfigured ATM PVC whose parameters are

used as a template when AHB creates a new PVC.
