Problem: there are AIX test machines, one is for application, and another is for database, all within the same network segment. And the application network has no problem, while the database machine has network problem, internal network downloading only has 30 KB data.
Solution: antitheses
As these two machines are within the same network segment, machine types are totally same, then you can make a detailed comparison of the network settings of these two machines, check what’s the difference, then change correspondingly.
Use the command netstat -v ent0 | grep -p "Specific Statistics" to check these two machines separately.
Application:
netstat -v ent0 | grep -p "Specific Statistics"
