The interface VLAN is down.
Possible Cause
The VLAN was not created.
Solution
Although VLAN <###> is not yet created, the NX-OS allows the configuration of the interface vlan <###>. As a result, the interface vlan <###> does not come up. Use the show vlan command to determine if VLAN <###> exists. If it does not exist, use the vlan <###> command to create the VLAN. After the VLAN is created, you must bounce the interface VLAN to have it come up.
Example:
switch(config)# interface vlan 600
switch(config-if)# no shutdown
switch(config-if)# show interface vlan 600 brief
-------------------------------------------------------------------------------
Interface Secondary VLAN(Type) Status Reason

switch(config)# show vlan id 600
VLAN 600 not found in current VLAN database
switch(config-if)# vlan 600
switch(config)# show vlan id 600

Possible Cause
VLAN was suspended by the vPC configuration on the Nexus 5000 pair.
Solution
Show that the vPC consistency parameters are global and make sure that the VLAN was not suspended. Otherwise, fix the configuration mismatch on the Nexus 5000 pair:
Example:
switch# sh vpc consistency-parameters global
Legend:
Type 1 : vPC will be suspended in case of mismatch
