Configuring the Allowed VLANs for PVLAN Trunking Ports

Isolated trunk and promiscuous trunk ports can carry traffic from regular VLANs along with PVLANs.
Before You Begin
Ensure that the PVLAN feature is enabled.
SUMMARY STEPS
1. switch# configure terminal
2. switch(config)# interface type [chassis/]slot/port
3. switch(config-if)# switchport private-vlan trunk allowed vlan {vlan-list | all | none [add | except | none
| remove {vlan-list}]}

OL-25842-01
Purpose
Enters global configuration mode.
Enables PVLANs on FEX trunk ports.
(Optional)
Saves the change persistently through reboots and restarts by
copying the running configuration to the startup configuration.
Purpose
Enters global configuration mode.
Selects the port to configure as a PVLAN host port. This port can be
on a FEX (identified by the chassis option).
Sets the allowed VLANs for the private trunk interface. The default
is to allow only mapped/associated VLANs on the PVLAN trunk
interface.
Note The primary VLANs do not need to be explicitly added to the
allowed VLAN list. They are added automatically once there
is a mapping between primary and secondary VLANs.
