I want to do some tests with the CNS 'Configuration Engine' and a ME-3400G-2CS-A (4 gig port Metro Switch) .
The target is to implement a zero-touch deployment of these switches but I am struggling with the very first step.
The ME-3400G should get its IP address from a DHCP server but gi 0/1 and gi0/2 are shutdown by default. When the switch is powered up I cannot see any DHCP request from the switch (it is factory default and starts with the config dialog). But the doc says it is possible and do not mention any restriction to the ports:
Since the dual-purpose ports on a ME-3400 are configured as UNIs by default, that means they are shutdown by default. The SFP-only NNI ports are enabled by default, but as you said, you can't use them sicne you don't have SFP modules.
you are right, even 'Zero Touch' needs to be touched :-)
But I thought of the possibility to give a device its initial config via dhcp (IP, hostname and CNS config) and the rest should be handled through the Config Engine.
As the switch does not have any config it should start with a dhcp discover if the initial config dialog will not be answered. I was wondering why I don't see this step when I am connected at the console of the ME-3400. So it seems that the dhcp requests will only be sent if one of the NNI ports is up and running or the requests are just invisible on the console.
I think I need the SFP modules to get a step further - and to get the device located locally and not at a remote site as it is currently...
