Configuring a native VLAN in no-default-native-VLAN trunk mode
The following examples illustrate the configuration of a native VLAN in a trunk mode where the native
VLAN does not exist. The native VLAN must be explicitly created in this mode.
The following native VLAN commands are supported in this mode:
• switchport trunk native-vlan-untagged
• switchport trunk native-vlan-xtagged
1. Configure a trunk port without a default native VLAN, then explicitly configure the native VLAN.
switch(config)# interface te 2/1/1
switch(config-if-te-2/1/1)# switchport mode trunk-no-default-native
switch(config-if-te-2/1/1)# switchport trunk native-vlan-xtagged 10 egress tagged
2. In no-default-native-VLAN trunk mode, configure untagged native VLAN 5000 and transport VLAN
6000, and make VLAN 7000 the default VLAN.
switch(config)# interface te 2/1/1
switch(config-if-te-2/1/1)# switchport mode trunk-no-default-native
switch(config-if-te-2/1/1)# switchport trunk native-vlan-untagged 5000
switch(config-if-te-2/1/1)# switchport trunk allow vlan add 6000 ctag 100-200
switch(config-if-te-2/1/1)# switchport trunk default-vlan 7000
3. In no-default-native-VLAN trunk mode, configure transport VLAN 6000 to accept C-TAG range 100
through 200 as well as tagged or untagged native VLAN traffic..
switch(config)# interface te 2/1/1
switch(config-if-te-2/1/1)# switchport mode trunk-no-default-native
switch(config-if-te-2/1/1)# switchport trunk native-vlan-xtagged 6000 ctag 10
egress any
switch(config-if-te-2/1/1)# switchport trunk allow vlan add 6000 ctag 100-200
Configuring additional Layer 2 service VF features
This section addresses additional features that are available on trunk ports once a Virtual Fabric is
established.
Configuring private service VFs
The following examples illustrate the configuration of a variety of private VLANs (PVLANs) as service
VFs and their association on access and trunk ports.
Refer also to PVLANs with service VFs on page 390.
Configuring service VFs and defining and associating PVLANs
1. In global configuration mode, use the interface vlan vlan_id command to create VLAN instances
that are greater than 4095, through 8191.
switch(config)# interface vlan 5000
switch(config)# interface vlan 6000
switch(config)# interface vlan 7000
2. In VLAN configuration mode, use the private-vlan command create the three types of PVLAN.
switch(config)# interface vlan 5000
switch(conf-vlan-5000)# private-vlan primary
switch(config)# interface vlan 6000
switch(conf-vlan-6000)# private-vlan isolated
switch(config)# interface vlan 7000
switch(conf-vlan-7000)# private-vlan community
3. Using the private-vlan association command, associate the secondary PVLANs with the primary
PVLAN.
switch(config)# interface vlan 5000
switch(conf-vlan-5000)# private-vlan association add 6000
switch(conf-vlan-5000)# private-vlan association add 7000
