GVRP LeaveEmpty takes longer than expected

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

Hi,

I apologize if this is not the right site to submit this question.
Please advise me if so.

We are using a commercial GARP application utilizing GVRP. The GVRP
enabled system has two ports that is set up similar to the UNH test
suite 12.2.1.2 ftp://ftp.iol.unh.edu/pub/bfc/tes [...] ation.pdf.

Occasionally I see that the LeaveEmpty packet is received much later
than expected. Debugging the protocol shows that the propagated port
for the Vlan Id is in the VP state (leaveall has expired on that port)
when the IndLeave occurs. The IndLeave transitions the port from the
VP to the VO state. The LeaveEmpty is not sent out until the port
expires on the next LeaveAll and the states transgress from VP, AA,
QA, LA.

The usual expected action would be that the IndLeave would occur when
the port is in the QA state causing a transition to the LA state.

Is this correct behavior? Reviewing IEEE 802.1D Applicant State table
it seems to have moved to the expected state when a IndLeave is
received on a port in the VP state

Any help would be appreciated.
