IGX 84xx clock problem over satellite, but not in lab.
Between 3 IGX 84xx node network (triangle) there seems to be a problem with the clock on one switch. The network is very unstable and is more busy with itself than passing traffic. There are lots of failures on the trunk as a result. Is this a SCM problem or..... All trunks go via satellite.
Re: IGX 84xx clock problem over satellite, but not in lab.
Passing clocks across a satellite link is typically challenging. The reasons are that though the satellites appear to be stable platforms, they move constantly relative to a point on the earth. As a result, there is a degradation of the clocking information due to Doppler shift.
To better answer your exact situation I need some more information:
1. What is the clock reference for your three nodes? each node? (dspcurclk and dspclksrcs)
2. Are you attempting to pass clocks across the satellites (i.e. pass sync = Y on cnftrk)?
3. Are you using your own v-sat terminals or are these links provided thru a commercial telco? If your own - what satellite modem and does it have built-in buffers? Which telco?
