Red Hat Enterprise Linux 7.3 server.
Kernel version: 3.10.0-514.el7.x86_64
I am trying to set MTU of one of the Intel NIC interface to 9000. By issuing this command: "sshpass -p pwd ssh host_name@Ip_address /sbin/ifconfig interface_name mtu 9000" via Putty SSH. Command didn't get succeed and it will through below error:
SIOCSIFMTU: Operation not permitted
However if I try to set MTU in the actual test machine using the system's terminal by using this command : "ifconfig interface_name mtu 9000" it will work.
I don't see this issue in 7.2 Server.
