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 Cisco Nexus 5000 Series Troubleshooting Guide 3-8 OL-25300-01
