Thank youThe problem was the settings on the BE switch.After making the changes, my problem was solved.
We has a cluster 12 Node EX300, to launch it, we followed the instructions of the company, which is abbreviated below: -First, we have made iDRAC settings on all Nodes, and access to it was done. [IMAGE] -In the next step, we entered the OS installation by  "ecs-os-setup.x86_64-3.7.0.1-1883.cb8e257.88.install.iso" and mounted the file to the server through iDRAC. [IMAGE]   -In the next step, according to the installation procedure, we tried to connect to IP 192.168.219.1 but this IP was not accessible. To continue the installation, we must have ssh access to this IP. [IMAGE]   Below are the images related to the output of the "ip a"  and other commands. Please guide me. [IMAGE]   [IMAGE]   [IMAGE] made all the physical connections of ports BE, FE, and iDRAC correctly and according to the document.
