The big reason that the switch needs to be able to _support_ 64 VLANs is
VTP.
If you have a number of 1912's acting as VTP clients to, say, a Cat 4006
with 35 VLANs configured then the client switches need to be able to
support information for at least 35 VLANs. This is irrespective of whether
the smaller switch actually has enough ports to host all those VLANs. Even
if all of the switch's ports are assigned to a single VLAN, it will still
carry the config info for _all_ the VLANs in the VTP domain.

Hi,
I am trying to understand whether the Catalyst 1912 switch supports upto 64
VLAN's(meaning connected to other vlan's) or you can create upto 64 VLAN's
on this switch. It has only 12 ports. If 1 port can only belong to 1 vlan
at
one time and each port is mapped to 1 mac address, then how come I can
create upto 64 vlan's on this switch.
Please advise.
Thank you.
Kind regards,
