NEC SV8100 Netlink issues

[Bowie88]

Hi Guys,

I have an ongoing fault with 2 x SV8100 systems netlinked together. The netlink keeps dropping and causing the secondary system to reboot. I'm looking for some input as to why this would be happening and also to see if anyone has had issues with Netlink like we are experiencing.

The customer has a link managed link between both sites of 10gig I think with a priority being put on voice traffic but we still get drops in the link.

All input would be greatly appreciated.

Here is some output from the alarm logs which i think covers the netlink dropping:

Most likely a network issue. Try a continuous ping across to the netlinked system. After that, set up a wireshark on the network.
