Appendix B: Status Information
This section details the information that is enabled by checking the
Reflect
Status
checkbox while configuring a service object. Figure 115 diagrams the
structure of this status information. Because this 16-byte structure resides in the
database at a user-designated location, it can be accessed from the opposite
port in order to continuously determine the performance of the corresponding
service object.

TX Counter
This is a 32-bit counter that increments when a packet is transmitted from the
gateway.
RX Counter
This is a 32-bit counter that increments when the gateway successfully receives a
valid packet.
RX Error Counter
This is a 32-bit counter that increments when the gateway receives an error
response packet or when an error occurs upon reception of a packet.
Current Status
This byte indicates the status of the most recently received packet. The status is
updated each time the RX Counter or RX Error Counter increments. Refer to
Table 16 for a list of currently used codes.
Last Error
This byte indicates the last reception error that occurred. The last error is
updated each time the RX Error Counter increments. Refer to Table 16 for a list
of currently used codes.
Reserved
These two bytes are currently unused but are reserved for future use.
