ADDRESSPAIR

The ADDRESSPAIR structure constructs a capture filter.

typedef struct _ADDRESSPAIR {
  WORD AddressFlags;
  WORD NalReserved;
  ADDRESS DstAddress;
  ADDRESS SrcAddress;
} ADDRESSPAIR, 
 *LPADDRESSPAIR;

Members

• AddressFlags
  Flags that describe the addresses used by a capture filter. See Remarks for more information.

  Value	Meaning
  ADDRESS_FLAGS_MATCH_DST	Matches the destination address.
  ADDRESS_FLAGS_MATCH_SRC	Matches the source address.
  ADDRESS_FLAGS_EXCLUDED	Excludes the frame if this address is found.
  ADDRESS_FLAGS_DST_GROUP_ADDR	Matches group bit only. Use this for broadcast-type messages.
  ADDRESS_FLAGS_MATCH_BOTH	Matches destination and source addresses.

• NalReserved
  This is reserved.

• DstAddress
  Destination address of the address pair element.

• SrcAddress
  Source address of the address pair element.

Remarks

The flags of the AddressFlags member can be combined. For example the following setting excludes the frame if the specified source address is detected.

ADDRESS_FLAGS_MATCH_SOURCE|ADDRESS_FLAGS_EXCLUDED
