Description (partial)

Span sessions spanning source ports in the TX directions may not work. 
It means that the destination interface does not send any packets out to 
the attached sniffer. Spanning the source ports in the RX direction 
always works instead.

Example of non working span config:

span session 8
  destination interface fc3/39
  source interface fc3/14 tx

After the MDS has been upgraded via ISSU to version 5.2(8b) from 5.0. Previous
