Problem: 

The Interface / Media Speed is incorrectly set on an AIX platform.  How can this be changed via Command Line options?

Solution: 

To change the media speed of a network interface in IBM AIX:

# chdev -l 'ent0' -a media_speed='100_Full_Duplex' '-P'

Valid Options for media_speed are shown below:
 

  • 10_Half_Duplex
  • 10_Full_Duplex
  • 100_Half_Duplex
  • 100_Full_Duplex
  • Auto_Negotiation

Note: The "-P" flag makes this a permament change.

Example:

 

chdev -l 'ent0' -a media_speed='100_Full_Duplex' '-P'
