Configuring An Isolated Trunk Port - Cisco Nexus 6000 Series Configuration Manual

Configuring Private VLANs
Step 6
The following example shows how to configure Ethernet interface 1/1 as a promiscuous trunk port for a
PVLAN and then map the secondary VLANs to the primary VLAN:
switch# configure terminal
switch(config)# interface ethernet 1/1
switch(config-if)# switchport
switch(config-if)# switchport mode private-vlan trunk promiscuous
switch(config-if)# switchport private-vlan mapping trunk 5 100
switch(config-if)# switchport private-vlan mapping trunk 5 200
switch(config-if)# switchport private-vlan mapping trunk 6 300

Configuring an Isolated Trunk Port

In a PVLAN domain, isolated trunks are part of a secondary VLAN. Isolated trunk ports can carry multiple
isolated VLANs. Configuring an isolated trunk port involves two steps. First, you define the port as an isolated
trunk port and then you configure the association between the isolated and primary VLANs. Multiple isolated
VLANs can be enabled by configuring multiple associations.
Before You Begin
Ensure that the PVLAN feature is enabled.

Configuring an Isolated Trunk Port
Purpose
(Optional)
Removes the PVLAN mapping from the port. If the
primary-vlan-id is not supplied, all PVLAN mappings are
removed from the port.
Purpose
Enters global configuration mode.
Selects the port to configure as a PVLAN isolated trunk
port. This port can be on a FEX (identified by the chassis
option). The PVLAN isolated trunk port can be configured
on a Ethernet port and on a FEX port.
If this is a 10G breakout port, the slot/port syntax
Note
is QSFP-module/port.
If this is a QSFP+ GEM or a breakout port, the port
Note
syntax is QSFP-module/port.
Configures the interface as a Layer 2 interface and deletes
any configuration specific to Layer 3 on this interface.
Configures the port as a secondary trunk port for a PVLAN.
Note The secondary keyword is assumed if it is not
present.
