The management interface media on a BIG-IP tenant running on F5OS systems does not match the media/speed of the management interface on the system controllers. Running 'tmsh show net interface' reports the media of the management interfaces (i.e. 'mgmt' or '1/mgmt') as "100TX-FD".
The media is reported as "100TX-FD".
BIG-IP tenant running on F5OS systems (rSeries or VELOS).
Ignore the speed reported for the tenant's management interface(s), and instead, look at the speed of the management interfaces as reported in F5OS. While running confd, run the following command to see the correct media settings: VELOS: show interfaces interface 1/mgmt0 rSeries: show interfaces interface mgmt
