Subject: Loop issues


The loop issues discussed in earlier emails with respect to the default VLAN
is not a *default* VLAN issue.

The problem (if there is one) manifests itself anytime one device maps a
frame to a different VLAN than another VLAN device.  The "default" VLAN is
just a special case of this issue.

I think that the discussion should separate into
 1) the need/desire for a default VLAN and
 2) the issue of inconsistent VLAN mappings and possible loops.

Also, I am curious if we can come to closure in June on the other requests
that I made.  Specifically:

- VLAN ID 0 is an invalid ID - never used.
- VLAN Ethernet frame format is never less than 68 bytes (4 more than min
  Ethernet frame).

Thanks - Steve
