Description (partial)

Symptom:
In the Configuring an ERSPAN Port Profile documentation, http://www.cisco.com/en/US/docs/switches/datacenter/nexus1000/sw/4_0/system_management/configuration/guide/system_7span.html#wp1251544,
the following steps are ommitted:
  vlan <vlan-id>
    name <vlan-name>
  port-profile <port_profile_name>
    switchport mode access

The VLAN should be created before configuring the ERSPAN port-profile, the port-profile should have 'switchport mode' configured before the 'system vlan' command is executed.

Without the above config, the 'system vlan <vlan_id>' command in step 6 will not be accepted.
n1k-pri(config)# port-profile dummy
n1k-pri(config-port-prof)# capability l3control
n1k-pri(config-port-prof)# vmware port-group dummy
n1k-pri(config-port-prof)# switchport access vlan 123
n1k-pri(config-port-prof)# no shut
n1k-pri(config-port-prof)# system vlan 123
ERROR: Mode not set. Please configure switchport mode and
allowed vlan (list) before system vlan configuration.
Inherited properties, if any, are not used for system vlan validation
