AIX Tip of the Week

Recovering TCP/IP Routes

Audience: All

Date: July 31, 2003

The following command restores TCP/IP routes stored in AIX's ODM. (routes created with the "smit route" or "chdev" command).

mkdev -l inet0

To see which routes are stored in ODM, run

lsattr -El inet0

This is useful if you lose or inadvertently change the IP routing table, as I recently learned the hard way when I detached a Gigabit Ethernet to change a hardware setting. AIX dynamically rerouted to a 10/100 Ethernet, which caused performance problems.
