Hello Everybody
I will appreciate your comments about the next issue that I see in my LAN:
I have an RB3011 that shows in the next image:

You can see the red line where there is an IP which entry is Ether10 interface
Results that the only interfaces actives are the Ether1 (WAN) and Ether2 (LAN) on the router, the IP addressing is static, the IP 192.168.42.2 is an AD WIN Server, this specific IP has intermittency, I mean, it loss connectivity and affects the connectivity of the other end users
I will appreciate your recommendations or comments about this
