Switching

Unlike the EX3300, EX3400 doesnot seem to have ethernet-switching-options when we can specifiy secure-access-port and limit the amount of mac addresses on an interface.

For example:

ethernet-switching-options {
secure-access-port {
    interface ge-1/0/26.0 {
        mac-limit 1 action drop;
        no-dhcp-trusted;
         }

    }

}
I can't seem to find an alternative configuration for EX3400.

NOTE: My EX3400 is running on Junos 18.4R1.8

Any ideas would be much appreciated. Thanks!

The EX3400 uses enhanced layer 2 software, details of which can be found here:
