GVRP question |
|
|
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... |

GVRP is used for propagation of VLAN configuration information.
With a single switch, there is nothing to propagate - all the
configuration would have to be done by hand. To see GVRP in
action, you would need at least two switches. Then you would
hand-configure the VLAN membership for the ports connected to
end-stations and GVRP would correctly determine the VLAN
membership for the switch-to-switch link.

Anoop,
I am curious to know that, would the VLAN configuration be passed on to
second switch from switch on which hand configuarion was done through
GVRP even if only one link exists between the two.
Because in this case switch one would not declare it's attributes as
there is no other link active.
Could you clarify this??
Thanks in advance!!

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.

Thanks for your reply!!
Well so it means Switch 1 (where VLAn's have been manually configured)
would not send anything on the link between Switch 1 and Switch 2 until
leaveall timer expires for registered attributes on port 1.
I assume all Static VLANs on Switch 1 have fixed registration so Switch
1 port would not un-register any attribute but Switch 2 can now know
about the attributes registerd on Switch 1 and may registers those
attributes.
Would this work??
If not then how is Switch 2 going to learn about the configuration on
Switch 1?
Kindly suggest.
Sincerely,
Jassy |

Re: GVRP question |

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 |
