This specifies the default maximum time (in milliseconds) for
the retransmission timer.
Using the /etc/rc.config.d/nddconf File to Set the ndd Tunable Parameters
The /etc/rc.config.d/nddconf file contains the tunable parameters that are
automatically set during system startup.
The /etc/rc.config.d/nddconf file contains the following fields:
TRANSPORT_NAME
Specifies the name of the transport component.
NDD_NAME Specifies the name of the ndd tunable parameter.
NDD_VALUE Specifies the value for the ndd tunable parameter.
To enable ndd to read the input from /etc/rc.config.d/nddconf file and set the
value of the tunable parameter during system startup, enter the following command:
ndd —c
Example 2-4 Configuring an SCTP Parameter in the /etc/rc.config.d/nddconf
file
To set the sctp_rto_max parameter to 65000 milliseconds, the
/etc/rc.config.d/nddconf fields must be specified, as follows:
TRANSPORT_NAME [1] = sctp
NDD_NAME [1] = sctp_rto_max
NDD_VALUE [1] = 65000
Using the netstat Command
This section discusses the various command-line options supported by netstat. It
also provides a sample output for each option.
This section addresses the following topics:
• “Displaying the Protocol Statistics” (page 30)
• “Displaying the Routing Table Information” (page 34)
• “Displaying Network Interface Status”
• “Displaying the Status of Sockets ” (page 36)
The netstat command supports command-line options, to display statistical
information for the network interface and the protocol. The output format varies
depending on the command-line option. For information on the command-line options
supported by netstat, see netstat(1).
Displaying the Protocol Statistics
To display per protocol statistics for the SCTP, UDP, TCP, ICMP, Internet Group
Management Protocol (IGMP) and IP protocols, enter the following command:
netstat -s
