[f-nsp] Odd MRP problem

[Peter Olsen]

Strange,

 

We have 150+rings active, never seen anything like this.

Except for the very strange numbers, is the ring working ?  (is it only
a 'counting' issue)

 

Br,

Peter

See this diagram for reference:

This is pretty simple.  I have one vlan in an MRP ring through 4 MLX
units.  I configure the master, and it works as expected.  I then
configure the members.  The problem is when the last "member"
(non-master) is configured in the ring, the master begins to receive
thousands of RHP and TC RBPDUs per second.  It doesn't matter which one
is the last member configured but as soon as I enable RHP on that last
member, the count of RHP and TC RBPDUs goes haywire.  Here is what my
master currently shows:

RHPs sent            RHPs rcvd            TC RBPDUs rcvd
509883               4193162              3684318

As you can see, it has sent about a half a million RHPs but received
over 4 million of them!

Only one unit is configured as "master".  As long as I have MRP
unconfigured on one of the members, the ring works as expected. There is
no spanning tree of any sort running on that vlan.  I am just in awe of
how RHP packets can seemingly be created in the network somewhere at
such an amazing rate!

Anyone else seen anything like this?  It is just plain wacky!

George
