I have Mikrotik CCR1036-12G-4S router and Cisco Catalyst 2960-X Series Switch in the Office
The Office is on 2 floors. Mikrotik is on the second floor and the switch on the first. The distance between Mikrotik and Cisco is 50-60m.
On the Switch I configured the only SSH, and on Mikrotik I configured the DHCP server.
On the Switch, there are connected PCs, Printers and Scanners.
For this network I got new subnet 192.168.150.0/24
when I finished everything, the devices got IP addresses and work properly, but after 10 minutes the devices lost IP addresses.
I tried to change the lease time, the default time is 1 hour, and I changed it to 10 minutes.
Devices got IP addresses when lease time is starts again, but in some minutes they lost.
On the Devices, when I change DHCP configuration to static, the devices are pinging, but on DHCP they lost IP.
If you have any solution please advise me to fix this problem.
