@alimdi The switch is not responding to the ARP request from the Linux server due to a misconfiguration. Try double-checking the settings of both the switch interface and the Linux server's virtual interface, as this should resolve the issue.

  @alimdi If the switch is not responding to the ARP requests from the Linux server, then it is likely a configuration issue. Check the switch configuration and make sure that the VLAN interfaces are properly configured on both the switch and the server. Additionally, ensure the port is enabled on the switch and that there is no firewall blocking the traffic. If after doing those checks, the issue still persists, please contact your network administrator for further assistance.
