Nexus 5K - SVI Interface Down after installing Enterprise Licence

Hi Community,

I have a Nexus 5K with no licence installed which is about to get in production in our network. I tried to install a LAN_ENTERPRISE_SERVICES_PKG licence and faced a unexpected behaviour in the equipment.

After have installed that licence in the equipment, an SVI interface which was up and working properly went down making the equipment unreachable in our network. After have uninstalled the licence, SVI came up again.

WNCPQACCN1# sh int vlan 999
Vlan999 is down (Non-routable VDC mode), line protocol is down
  Hardware is EtherSVI, address is  002a.6a5a.6f41
  Description: "Gestion in-band"
  Internet Address is X.X.X.X/X
 MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec

After some googling I found that it has happened because I activated an L3 base licence without having a L3 Routing Module installed but it did not convince me and I would like a more technical explanation why it has happened. Does anyone know about a documentation where this behaviour is explained?


Any input will be appreciate.

Cheers,

Antonio
