Re: Sigtran Links

Hi Aditya,

 Thanks for reply.

I have taken this trace next day after starting gctload at time of starting
gctload i have not taken tarce.Once the switch engineer sent this alarms i
have started taken trace.I have restarted the server at 1:48 PM on 24/03/09
but i see some alarams at 3:29PM and 4:58PM on 24/03/09 as M3UA DESITINATION
INACCESSIBLE but when i check in gctload i have not seen any information
regarding link down.

In trace i have seen that ASPUP and ASPAC when i have restarted the gctload
but i have not saved that trace.

Coming to traffic still they have not routed any traffic to our server still
waiting for traffic as once this alarams stops they are planning to send
traffic to server.They are complaing only for alarms.

Request you to please explain me why this alarms are genarating in switch as
there is no traffic to server and as we are not using SG and m3ua for long
time for this reason we are getting this alarms or any other reason.

Can you please explain what is "ceased" state.


Thanks & Regards
