The range of domain IDs is from 1 to 1000.
7. Enter the port-channel number that acts as the interconnect trunk.
VLT DOMAIN CONFIGURATION mode

8. (Optional) To configure a VLT LAG, enter the VLAN ID number of the VLAN where the VLT forwards packets received on
the VLTi from an adjacent peer that is down.
VLT DOMAIN CONFIGURATION mode
peer-link port-channel id-number peer-down-vlan vlan interface number
Associating the VLT LAG or VLT VLAN in a PVLAN
1. Access INTERFACE mode for the port that you want to assign to a PVLAN.
CONFIGURATION mode
interface interface
2. Enable the port.
INTERFACE mode
no shutdown
3. Set the port in Layer 2 mode.
INTERFACE mode
switchport
4. Select the PVLAN mode.
INTERFACE mode
switchport mode private-vlan {host | promiscuous | trunk}
● host (isolated or community VLAN port)
● promiscuous (intra-VLAN communication port)
● trunk (inter-switch PVLAN hub port)
5. Access INTERFACE VLAN mode for the VLAN to which you want to assign the PVLAN interfaces.
CONFIGURATION mode
interface vlan vlan-id
6. Enable the VLAN.
INTERFACE VLAN mode
no shutdown
7. To obtain maximum VLT resiliency, configure the PVLAN IDs and mappings to be identical on both the VLT peer nodes. Set
the PVLAN mode of the selected VLAN to primary.
INTERFACE VLAN mode
private-vlan mode primary
8. Map secondary VLANs to the selected primary VLAN.
INTERFACE VLAN mode
private-vlan mapping secondary-vlan vlan-list
The list of secondary VLANs can be:
● Specified in comma-delimited (VLAN-ID,VLAN-ID) or hyphenated-range format (VLAN-ID-VLAN-ID).
● Specified with this command even before they have been created.
● Amended by specifying the new secondary VLAN to be added to the list.
