Vlan Interface down and won't come up

I have a Nexus 5548 and I created a vlan 1211 and then a interface vlan 1211.  When the interface was created the it was named, given an IP address and a no shutdown command.  When I do a show interface vlan 1211 I get Vlan1211 is down (VLAN is down), line protocol is down.  I thought that I may need to have an active Ethernet port untagged in the VLAN so I did that with switchport access vlan 1211 on an test active Ethernet port.  The results are the same.

 

I have done this with many other VLANs but for whatever reason this one is giving me problems.  Does anyone have any ideas?

Eric

Hi Eric,

 

Its important to note that Nexus 5548 run NX-OS not IOS. Have You enabled the SVI feature with the "feature interface-vlan" command?

Hi Eric,What does "show vlan

Hi Eric,

When you created other VLAN's on this switch, did you assign IP addresses to them? Like Steve said, without the "feature interface-vlan" you cannot configure an SVI.
