Does TIM support ERSPAN with GRE?



All APM environments up to and including 10.3.



APM does not officially support ERSPAN with GRE.  It is possible to get it working without the GRE tunneling.  


There is some limited success if terminating the GRE Tunnel on the local TIM machine. Then making sure that the data comes out not as GRE data to an interface to then feed the TIM apmpacket process.  Some testing with that technique showed various issues with bandwidth.
