chdev - how to change the media speed of a network interface in IBM AIX

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

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

Possible values for media_speed are:

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'
