3850 management not working on SVI IP VLAN

Good Morning.

 

I have two SVIs configured on my switch. One IP address on VLAN 1 Default (192.168.0.15) and another on VLAN 50 (10.50.50.15), but web and telnet access is only taking place via the IP address of VLAN 1.

 

From my station I can ping the IP of VLAN 50.

 

I would be grateful if someone could help me.

I believe that this image can help a little to understand the situation:topology.png

Guys, I continued to investigate further and analyzed the packets in the 3850. As you can see in the image below, the 3850 even sent a syn-ack,  but did not get the station's ack.

So, at first I thought it could be something in the configuration of the route between the VLANs on the router, but as I was able to normally access all the other devices on the VLAN 50, I insisted that the problem was really with the 3850.

And it is with joy that I come to share with you that I managed to solve the problem. I simply removed the IP address from VLAN 1 and deactivated it:

interface Vlan1
no ip address
shutdown
!

 

Now I can access and manage the 3850 normally via VLAN 50.

Thank you all so much!
