Port name formatting

Some node like qemu allow you to personalize the name of ports in order to match the name of the interfaces inside the emulator.

Simple syntax

The first {} will be replace by the interface number

For example: “eth{}” will give:

  • eth0
  • eth1
  • eth2

Or more verbose “eth{port0}” and “eth{0}” will do the same.

Use segments

Segment allow you to split your interface in multiple ports

For example “Ethernet{segment0}/{port0}” with a segment size of 3:

  • Ethernet0/0
  • Ethernet0/1
  • Ethernet0/2
  • Ethernet1/0
  • Ethernet1/1

You can also change the start number.

For example “Ethernet{segment1}/{port1}” with a segment size of 3:

  • Ethernet1/1
  • Ethernet1/2
  • Ethernet1/3
  • Ethernet2/1
  • Ethernet2/2

This work from port0 to port9 if you need a bigger range ask us.
