switch#
Configuring interface to access port does not allow VLAN <###> to go through
After configuring an interface to access a port for allowing VLAN <###>, the VLAN <###> does not go
through.
Possible Cause
The VLAN was not created.
Solution
In NX-OS, configuring with the switchport access vlan <###> command on an interface does not
automatically create VLAN <###>. You must specifically create VLAN <###> using the vlan <###>
command. Use the show vlan command to determine if VLAN <###> exists. If it does not exist, then
use the vlan <###> command to create the VLAN.
Cannot create VLAN
The VLAN cannot be created.
Possible Cause
All VLAN resources are exhausted.
Solution
For the Nexus 5000, the maximum number of active VLANs and VSANs per switch is 512 (31 reserved
for VSAN; remainder reserved for VLAN). Use the show resource vlan command to determine the
number of available VLANs.
Example:
switch(config)# show resource vlan
