Nexus 5548 interface vlan is not getting up

[Sharanjeet_Kumar]

Hi team,

I have a single nexus 5548 using as NXOS, create 2 interface vlan (SVI) after enabling feature interface-vlan, but both SVIs is down, i did the no shutdown but still it is in down state meanwhile the core switch 92180 svi is up 

Interface is trunk and all vlans are allowed

i already used command feature interface-vlan

I did the no shutdown to both interfaces

in NSK you need to add VLAN so 
vlan 10 
vlan 11 

if there is no l2 port assign to this vlan you need to use 

no autostate <<- under VALN SVI

I assume you didn't create the VID at L2? Or did you enable the feature? 

feature interface-vlan 

vlan 10 
 name XXX
vlan 11
 name XXY

Hello @Sharanjeet_Kumar ,

you need to have at least one L2 port assigned to corresponding VLAN that is up/up with STP state forwarding.

This is called autostate and it is a concept that was already present on Cisco switches running IOS like Catalyst 6500 or Catalyst 4500.

To be noted a L2 802.1Q trunk port can be used to carry multiple VLANs ( L2 broadcast domains) to some other device.

So either you have at least one active port in Vlan 10 that is an access port or the VLAN 10 is allowed and active on a  L2 802.1Q trunk port. The same for the other VLAN 11.

Hope to help
