Issue

I want to have my eth0 management port use VLAN tagging. How do I configure this?

Environment

• Cumulus Linux 2.0.x
• Cumulus Linux 2.1.x
• Cumulus Linux 2.2.x
• Cumulus Linux 2.5.x

Resolution

Configure a VLAN subinterface for eth0 in /etc/network/interfaces. Do one of the following:

• If eth0 is configured with DHCP, use something similar for the second stanza below:

  auto eth0
  iface eth0
  
  auto eth0.TAG
  iface eth0.TAG dhcp
  

  Where TAG is the VLAN tag number.

• If eth0 is configured with a static IP address, use something similar for the second stanza below:

  auto eth0
  iface eth0
  
  auto eth0.TAG
  iface eth0.TAG
      address specify.some.address.here/mask
  

  Where TAG is the tag number and the address line contains the static IP address and netmask for eth0.
