= Hi,

When M3UA H= eart beat loss is detected at local node due BEAT ack  not received fo= r the BEAT message sent and Heart beat timer times out it makes the ASP&nbs= p; down locally.
Currently there seems to be no action = take when the M3UA layer makes the ASP  down. The l= ocal node does not  send any message towards the core network for brin= ging up the ASP.
So I would like to know once ASP is down due to HB l= ost at M3UA layer then how does the local node recover the M3UA layer ?
 

Best Regards,
Suchetha

Hi Brian,

Thanks for your response.
I see that the "local" system is not initiating ASP UP message nor abor= ting the association.
Inord= er to recover  from the ASP down state the "local system" expects M3UA= BEAT,ASP UP messages from the peer which the peer is not initiating.
The M3U= A Heat beat mechanism needs to be enabled at both the ends isn't it ?
=
I see that the= M3UA Heart beat is disabled at the remote end resulting in no response fro= m the peer for the BEAT message sent by the "local system".
If M3UA Heart beat was e= nabled at the remote end then on receiving BEAT from the remote node "loca = system" would have responded with BEAT ACK resulting in ASP UP.


Best Regards,
Suchetha
