GVRP question

Archived from groups: comp.dcom.lans.ethernet (More info?)

Hi !

Does anybody knows some basic facts about GVRP protocol and is it possible
to represent its functionality on a single switch with two computers
attached to it?

Thanks...

If the the two switches 1, 2 are connected by a single and there
is no other link active on either switch, there is nothing for
the switches to tell each other. A switch will use GVRP to
tell another switch about VLAN configuration on all of its ports
other than that connected to the other switch.

Anoop may be mentioned something ghastly wrong over here.
Sorry about that!!
Actually I am a newbie and trying really really hard to understand
GVRP/GARP.
But so far very little success.
There are many issues for which I am looking the awnsers for.

1. Could you please elaborate on how LeaveAll state machine works. I am
sure i don't understand the concept.
2. LeaveAll messages are sent out of physical port always.?? Is that
correct.
e.g
if A and B ports of a switch are part of GIP context on a switch.
And leaveAll timer expires on port A. Then A would send out a message
to other devices connected to its side but port B would still manage
it's own state machines, i.e. unaffected by LeaveAll event from port A

Please elaborate.

Thanks,
Jassy
