From a workstation within the campus network (preferably in the classroom or lab area where students use SAM), run the Tracert sam.cengage.com command from the Windows command line

Note For MacOS or Unix/Linux, use traceroute sam.cengage.com.
C:\>Tracert sam.cengage.com

Trace complete.

The first column is the network hop count, and the fourth column is the transmit time.

  • More than 18 hops may potentially cause issues.
  • Transmit times should be no more than 40-120 ms.

Ping Testing

From a workstation within the campus network (preferably the classroom or lab area where students and instructors use SAM), run the following command from the Windows command line:
Ping -t sam.cengage.com
Note For MacOS or Unix/Linux, use ping sam.cengage.com.
  • The round trip times should be less than 120 ms for optimal performance.
  • Packet loss should be under 1% for optimal performance.
