Description Pekka Järvinen 2018-09-22 09:42:09 UTC
Hello!

man page:
group group-name
  Assign the interface to a group. Any interface can be in multiple groups.
  Cloned interfaces are members of their interface family group by
  default. For example, a PPP interface such as ppp0 is a member
  of the PPP interface family group, ppp.
  
My questions:
- So what is a group actually? What it does or doesn't do to those interfaces? Is it simply cosmetic?
- When I need to (or not) assign something to group?
- Are there security implications with group?
- Are there performance implications with group?
