You must check the Speed and Duplex of the SSIM appliance, but when the ethtool utility is ran it only displays the Current message level and Link Detected information.
Output appears as below.
Settings for eth0:
Current message level: 0x0000007 (7)
Link detected: yes
The SSIM is installed to VMWare and VMWare Tools has not been installed yet.
Install VMWare Tools to the VMWare Guest that SSIM is installed on and the ethtool command returns Speed and Duplex information.
If assistance is needed with installing VMWare Tools, then contact VMWare for assistance.
