TCPRECVSPACE int
specifies the size of the window used for receiving data for the TCP protocol. This
value affects the performance, as it is mapped to the advertised window. The
recommended range is 512 bytes to 12k bytes. The default value is 8K. It is
recommended that this value not be set too low (below 2K).
UDPSENDSPACE int
specifies the size of the window used for sending data for the UDP protocol. The
recommended range is 512 bytes to 12k bytes. The default value is 9216.
UDPRECVSPACE int
specifies the size of the window that is used for receiving data for the UDP
protocol. The recommended range is 512 bytes to 12k bytes. The default value is
41600. It is recommended that these values not be set too low (below 2K).
DELAYACKS { ON | OFF }
specifies whether acknowledgments for TCP packets be sent immediately (as soon
as a packet is received). This mechanism allows more that one packet to be
acknowledged with a single ACK. This helps reduce the network traffic. It also
allows the TCP window to be filled up before an ACK is generated. The default
value for DELAYACKS is ON.
DELAYACKSTIME int
specifies how much the delay time is before an ACK (acknowledgment) is sent for
a packet. This is useful only if the DELAYACKS parameter is ON. It is specified in
intervals of 0.01 seconds. The default value is 5 (50 milliseconds). The range is 1
through 50. It is recommended that the value of this variable not be greater than 20
(200 milliseconds).
HOSTNAME string
is the official name by which the host upon which the TCP6MON is running is
known to the Internet. This is a character string no longer than 50 characters. The
default value is null.
HOSTID int
is the identification number (usually the host number part of the Internet address
that is assigned to this host). It is a 32-bit number.
TCPKEEPIDLE int
is the amount of time in seconds before TCP issues a keep-alive packet on sockets
that have enabled this option. The default is 45 seconds. The range is 1 to 7200.
