Missing "no shutdown" command from configuration uploaded using SCP

[roman.vilu]

Hi

Have a problem with a Cisco ISR4331 router (image isr4300-universalk9.16.09.05.SPA.bin).

1. Successfully uploaded configuration using SCP

2. Router reboots and loads new configuration

3. Configuration is successfully applied, but there are no shutdown command missing from configuration on physical interfaces

In result, interface GigabitEthernet0/0/0 and GigabitEthernet0/0/1 need to by manually enabled. The router gives no errors related to configuration during startup, interfaces settings include only description and no shutdown commands.

Question: what could be a problem causing no shutdown be missed from configuration? Thank you!

No.

3. Configuration is successfully applied, but there are no shutdown command missing from configuration on physical interfaces

if you do not see any "no shutdown" under interface means, the port is in active mode. (as per I have seen you see an only shutdown in interface command)

show run all ( see under interface )

[roman.vilu]

I also see administratively down in

show ip interface brief

and message on startup:

SETUP: new interface GigabitEthernet0/0/0 placed in "shutdown" state

 - Show  interface configuration from running-config.

Ok can you give sample interface config that was uploading to Router.

[marce1000]

 - But

 no shutdown

is a defaulted condition for an interface and it should start by default too , check logs if that does not happen.

It seemed to be so, but I have also tried to upload configuration without

no shutdown

but it is still shut by the router.

What does the log say if the port is manually enabled?

[roman.vilu]

If manually enabled, then it is OK and says that interface put in down state (nothing is connected to that port).

[marce1000]

 - Consider that as normal, the only important thing is that the port becomes connected when something is attached to it.

Wait, what?  If the port was not manually enabled, was it "administratively down" or just "down"?

Thank you all for your help! Problem is solved. Probably the thing was that there was not

ip address

command specified. If it is, ports are successfully enabled after startup.
