<p class="MsoNormal">I'm exporting pcap's from the machine to a tftp server over the internet. But the 912 runs out of memory and pauses the pcap process and thus far I haven't been able to get a single decent pcap to show the carrier.<u></u><u></u></p>

<p class="MsoNormal">I've been on with Adtran support and their answer is to put the tftp server closer to the adtran so that exports finish faster. I'm doing that and will have it done in the am.<u></u><u></u></p>

<div>
<p class="MsoNormal">However I thought I'd ask if there's a magic process that anyone has found for getting good pcaps from these devices. They seem to work well, but troubleshooting is a bitch. You can even log the debug. You have to keep a damn terminal open
and hit a key every 4 minutes to not disconnect.<u></u><u></u></p>
