CirrusIssue on management route
Hi everybody,
I added a static route on the management interface to send logs towards Syslog server; if I type the ip route get "IP address" command, I can notice that destination address should be reached by the right interface (management).
But if I perform a tcpdump on the mgmt interface, with a filter on the destination IP address, I can notice that the source IP address becomes another, NOT the management IP.
Can youhelp me to solve this issue?
Thanks a lot in advance, best regards.

romolo82I add that in the routing tble there is a default route that use the interface with the wrong IP address that now is forwarding logs; but a static route shouldnt' be preferred than a default route?

Hi romolo82,
I have encountered this problem before 🙂
Have you set the local IP parameter on Syslog Configuration remote logging ?

Just to clarify, Did you set this route via cli or UI?
if its management it has to be the cli, the ui is only the data plane for prod traffic.
K13284 commands are key here and make sure your gateway is correct!- romolo82
