DSP total Channels/active channels not returned properly on SNMP

Unanswered Question
May 27th, 2009


I did a SNMP walk on a AS5400XM MediaGateway for getting the number of total number of DSP channels available as well as the active DSP channels in it.

We were using OID for DSP Active Channels and for DSP Total Channels. For total channels we are getting 56 indexes with 16 as value for each, so ideally the count comes to 896 only but there are 16 64-channel DSP cards, which is 1024 channels and "show voice dsp summary" also shows that there are 1024 channels available. The same does happen for Active channels too, we are getting 56 indexes only. If we get 64 indexes then we will be getting 1024 channels.

Do let us know if we are missing something or do we need to configure anything on the device to give proper value on SNMP.



I have this problem too.

ensure all the DSP cards are functioning properly or not. Please reinsert the card and try.
