Solaris Question - How to find outgoing traffic on UDP ports

UNIX Solaris
1

Hello All,

I am trying find a command that would show me the stats of outgoing traffic on UPD ports on a Solaris 10 box. I would appreciate if anybody could help me out on this.

Thank you much!!!

Best Regards

netstat -a to see what UDP ports are open.

netstat -sd to get a summary of the traffic

Thank you very much...

when i ran netstat -sd , got the following result..

--- Entry 2 ---
Group = 263, mib_id = 0, length = 40, valp = 0x8078688

UDP udpInDatagrams = 3290 udpInErrors = 0
udpOutDatagrams = 3307 udpOutErrors = 0

what is 3290 and 3307 here ??

Thank you again!!

packet counts

By the way, you can use the -P udp modifier to only receive UDP information
