Hello Guys,
Good Day !!
c-Edge devices not sending UDP packets for Control Connections while communicating SD-WAN control controllers: vSmart and vManage.
The control communication happen on UDP ports with vBond but after some random time the connection with vBond auto renew.
Due to this issue c-Edge devices on-boarding not happen successfully.
Refer below PCAPs for the reference and request you to please help me if anybody have the solution for this:
cEdge-2#sh mon cap vbond buffer br
----------------------------------------------------------------------------
# size timestamp source destination dscp protocol
----------------------------------------------------------------------------
0 182 0.000000 SRC IP cEdge Interface -> DEST IP vBond 48 CS6 UDP
1 182 1.000992 SRC IP cEdge Interface -> DEST IP vBond 48 CS6 UDP
2 182 2.001999 SRC IP cEdge Interface -> DEST IP vBond 48 CS6 UDP
3 182 3.003998 SRC IP cEdge Interface -> DEST IP vBond 48 CS6 UDP
4 182 4.005005 SRC IP cEdge Interface -> DEST IP vBond 48 CS6 UDP
5 182 5.007003 SRC IP cEdge Interface -> DEST IP vBond 48 CS6 UDP
c-Edge >>>>>>>> vSmart:
cEdge-2#sh mon cap vsmart buffer br
----------------------------------------------------------------------------
# size timestamp source destination dscp protocol
----------------------------------------------------------------------------
0 86 0.000000 SRC IP cEdge Interface -> DEST IP vSmart 48 CS6 ICMP

4 86 10.020004 SRC IP cEdge Interface -> DEST IP vSmart 48 CS6 ICMP
c-Edge >>>>>>>> vManage:
cEdge-2#sh mon cap vmanage buffer br
----------------------------------------------------------------------------
# size timestamp source destination dscp protocol
----------------------------------------------------------------------------
0 86 0.000000 SRC IP cEdge Interface -> DEST IP vManage 48 CS6 ICMP
1 86 0.720016 SRC IP cEdge Interface -> DEST IP vManage 48 CS6 ICMP
2 86 5.726012 SRC IP cEdge Interface -> DEST IP vManage 48 CS6 ICMP
3 86 10.732024 SRC IP cEdge Interface -> DEST IP vManage 48 CS6 ICMP
4 86 15.738020 SRC IP cEdge Interface -> DEST IP vManage 48 CS6 ICMP
But the traffic coming from Controllers to cEdge is properly communicating via UDP ports.
Early response is highly appreciated.
