The real answer for 2.4 is:
max age = ageing timer + gc interval
min age = ageing timer
Does ageing out only occur at GCINT? - that is, timing out MAC entries
is based on agingtime + remaining period in gcint??
On 2.4 ageing only occurs at the gc interval. On 2.5/2.6 the gc interval
setting is now ignored and the garbage collection timer is set to minimum of the
remaining entries. This means GC can run less often, but be more accurate
about aging as well.
