Description (partial)

1)	When we reload the primary DSC chassis then backup DSC takes becomes primary DSC but the traffic running on Satellite Access Ports are getting dropped in incremental percentage(nearly 40% in 20 mins)
•	I checked the ?sh nv sat status? and found that Tengig 1/0/2/0 port was replaced by Random GigE interface on RACK0 (Gig 0/0/1/14).

2)	Primary DSC (ASR90001-B) is S/W reloaded and checked the status of Satellite on newly Active DSC ASR9000-A that both of the Tengig link is replaced with Random GigE link(0/0/1/14) and  GigE 1/0/0/0.
•	SAT goes to Connecting State and doesn't recover from there.
•	SAT access ports got down and Satellite went to connecting state => 100% Traffic Loss.

When host within the cluster is S/W reloaded
