There are several ways to get this info.
# netstat -v | grep Speed
Media Speed Selected: Auto negotiation
Media Speed Running: 1000 Mbps Full Duplex
Media Speed Selected: Auto negotiation
Media Speed Running: 1000 Mbps Full Duplex
# entstat -d en0
#for en in `netstat -i | grep en | awk ‘{print $1}’ | sort -u | cut -c3`
>do
> adapter=`echo ent${en}`
> entstat -d ${adapter} | grep “Media Speed”
>done
To Change the Network Card speed on AIX –
#chdev -l en0 -a state=detach –> Detach the interface
#chdev -l ent0 -a media_speed=1000_Full_Duplex –> Make appropriate changes
#chdev -l en0 -a state=up –> Change the step to UP
[NOTE: Don’t do ifconfig enX up – this will put an IP address of 0.0.0.0]
#mkdev -l inet0 –> to activate all routes
Hope this will be helpful.
