Observing Solaris 10 tcp/ip stack

Hi, let's take a look for ususal network related command under Solaris 10. To understand how to things work deeply, see this page.

Routing table:

netstat -rn
Routing Table: IPv4
  Destination           Gateway           Flags  Ref     Use     Interface 
-------------------- -------------------- ----- ----- ---------- --------- 
default              192.168.89.2         UG        1         10 e1000g0   
192.168.89.0         192.168.89.130       U         1         22 e1000g0   
224.0.0.0            192.168.89.130       U         1          0 e1000g0   
127.0.0.1            127.0.0.1            UH        1         42 lo0

Seeing realtime amount of traffic:

netstat -in 1 100
    input   e1000g    output       input  (Total)    output
packets errs  packets errs  colls  packets errs  packets errs  colls 
931623  0     470008  0     0      931744  0     470129  0     0     
.
.

State of connections:

netstat -n -f inet
TCP: IPv4
   Local Address        Remote Address    Swind Send-Q Rwind Recv-Q    State
-------------------- -------------------- ----- ------ ----- ------ -----------
192.168.89.130.22    192.168.89.1.49728   65535      0 49232      0 ESTABLISHED

Status of interfaces:

dladm show-link
e1000g0         type: non-vlan  mtu: 1500       device: e1000g0
dladm show-dev 
e1000g0         link: up        speed: 1000  Mbps       duplex: full

Various statistic information related to protocols (like droppe TCP connections, and so on..):

netstat -s
