The global settings for the INTERVAL, HW_THRESHOLD, LW_THRESHOLD and
MAX_TH_LOGFILE_SIZE parameters will be ignored by ZGATE devices that do not sup-
port threshold filtering.
Static Filter Configuration
The format of a static filtering configuration record is:
"C" "," ","
In the above string, is a monotonically increasing number assigned to
the configuration settings by the creator of the file. ZGATE does not use, examine or vali-
date this value.
must represent one of the following parameters:
ETH_ADDR_FILTER
ETH_FRAME_FILTER
IP_SRC_ADDR_FILTER
IP_PROTOCOL_FILTER
TCP_PORT_FILTER
UDP_PORT_FILTER

Because static filtering is performed on inbound packets, the Ethernet address filter exam-
ines the source address of the Ethernet frame. Similarly, the TCP and UDP port number
static filters examine the destination port numbers of inbound TCP and UDP packets.
must represent one of the following parameters:
NONE
WHITELIST
HW_THRESHOLD Value ≥ 100; must be at least twice the
value of LW_THRESHOLD.
LW_THRESHOLD Value ≥ 20; must be less than half the
value of HW_THRESHOLD.
MAX_TH_LOGFILE_SIZE Number between 10 and 100 inclusive.
MAX_LOGFILE_SIZE Number between 10 and 100 inclusive.
