Trying to verify actual switchport speed

Connecting network adapter from 100MB switchport to a 1GB switchport.
Trying to verify actual switchport speed.

While connected to 100MB switchport
lsattr -R -l ent0 -a media_speed shows:
10_Half_Duplex
10_Full_Duplex
100_Half_Duplex
100_Full_Duplex
1000_Full_Duplex
Auto_Negotiation

lsattr -EH -l ent0 -a media_speed shows:
attribute value description user_settable
media_speed 100_Full_Duplex Media speed True

netstat-v shows (among other things):
Link Status : Up
Media Speed Selected: 100 Mbps Full Duplex
Media Speed Running: 100 Mbps Full Duplex

After connecting to 1GB switchport.
Regain "ping" in seconds.

chdev -P -l ent0 -a media_speed=1000_Full_Duplex
ent0 changed

lsattr -EH -l ent0 -a media_speed
attribute value description user_settable
media_speed 1000_Full_Duplex Media speed True

However:
netstat-v shows (among other things):
Link Status : Up
Media Speed Selected: 100 Mbps Full Duplex
Media Speed Running: 100 Mbps Full Duplex

What speed am I actually connected at??

Thanks,
