Identifies if the sequence number is added to every GTP-U packet. 

Include UDP Port Ext.Hdr 

Indicates if an extension header, in the GTP-U packet header, allowing for error indication 
messages will be added. 

Max-retransmissions 

The number of user data packet request message retransmissions that can be sent before an 
error condition is established. 

Retransmission Timeout 

The number of seconds between the re-sending of GTP-U echo messages 

IPSEC Tunnel Idle Timeout 

 The number of seconds an IPSec tunnel is idle before tunnel deletion is triggered. 

Allow Error-Indication 

Indicates if the error indication will be allowed or suppressed upon the receipt of a user data
