The Linkloop also tells if interface is up or down.

$  linkloop 0x00215A9165DB 
Link connectivity to LAN station: 0x00215A9165DB
 -- OK

Editing the /etc/rc.config.d/netconf file allows you to identify the network interface name, IP address, and subnet mask of your LAN card, and add entries to the network routing table.

To restart network:

/sbin/init.d/net stop; /sbin/init.d/net start

Command: linkloop

It checks connectivity within a LAN by sending data (through a direct Data Link Provider Interface) to the interface card. This is command to be used if IP level connectivity fails. The argument is MAC.

$  linkloop 0x00215A9C4FDD 
Link connectivity to LAN station: 0x00215A9C4FDD
 -- OK

Command: ndd

Kernel parameters are in the file /stand/system and configured with commands like kmtune and mk_kernel.
The networking-related parameters are not configured in this way. They are configured with command ndd.
They affect how various networking software components function as well as how they will react in certain situations. Changes made with ndd are immediate, but they are lost after reboot.
To make a change survive a reboot, configure them in the startup script /etc/rc.config.d/nddconf

To read input from the configuration file /etc/rc.config.d/nddconf and set the tunable parameters, run command:

# ndd -c

Command: Nettl tracing and logging

Nettl control network tracing and logging.

Tracing Information:
Trace Filename:
Max Trace file size(Kbytes): 0
No Subsystems Active

To start tracing in file 'test':

# nettl -tn all -e all -f test

Note:
-traceon (Abbr.: -tn)
-traceoff (Abbr.: -tf)
-entity  (Abbr.: -e)

To stop tracing:

# nettl -tf -e all

Use netfmt to format tracing and logging binary files.

Note:
-N = nice formatting
-n = show port, network address
-c = point to filter file
-f = input binary file

Example of filter file:

# cat filterfile
filter ip_saddr 16.216.98.206
filter ip_daddr 16.216.99.1

$  netfmt -N -n -c filterfile -f test.TRC000

IP/UDP/TCP LAYER TOOLS

Network interfaces are configured in the file /etc/rc.config.d/netconf

To see interface setting use ifconfig

$  ifconfig lan0 
lan0: flags=2000000000001843
        inet 16.216.98.206 netmask fffff800 broadcast 16.216.103.255

Use netstat to see all interface IP assignments.

$  netstat -in

To see MAC of interface use arp

$  arp g9u1158c 
g9u1158c (16.216.98.206) at 0:21:5a:9c:4f:dd ether permanent published

To see current AMC cashed for local subnet:

$  arp -an 
 (16.216.96.1) at 0:0:5e:0:1:2 ether
 (16.216.99.1) at 0:21:5a:9c:51:9 ether

 (16.217.100.104) at 0:21:5a:9c:51:d ether

To see routing table

$  netstat -rn

To list processes that has UDP port open use lsof

$  lsof -n | grep -i udp

Use ttcp (Test TCP) to check throughput between systems. Example, check port 25:

$  ttcp -stp25 g1o0007 
ttcp-t: buflen=8192, nbuf=2048, align=16384/0, port=25  tcp  -> g1o0007
ttcp-t: socket
ttcp-t: connect
ttcp-t: 106496 bytes in 0.08 real seconds = 1228.56 KB/sec +++
ttcp-t: 14 I/O calls, msec/call = 6.19, calls/sec = 165.38
ttcp-t: 0.0user 0.0sys 0:00real 0% 0i+0d 49maxrss 0+0pf 3+0csw
