ZGATE_get_received_stats
Function Prototype
void ZGATE_get_received_stats( char * pBuff );
Parameters
pBuff A pointer to a buffer into which received packet statistics will be
placed. This buffer should be at least 60 bytes in length.
Return Value
None.
Description
This function generates a NULL-terminated ASCII string containing a count of the pack-
ets processed by each of the ZGATE static filtering layers. The string contains the number
of packets processed by the following four filters, and in the following sequence: Ethernet
filter, IP filter, UDP filter and TCP filter.
These counts are for the static filters only. These counts do not reflect the number of each
type of packet received by the device – only those processed by each filter. For example,
most TCP packets will be recognized by the SPI filter as part of an existing connection.
Because these packets belong to a connection that has already been validated, these packets
will not be passed through the TCP static filter, and do not show up in the TCP filter packet
count. Note:
