NEC SV8100 - System Crash 1

[irongladiator]

Hello fellow NEC techs,
NEC SV8100 is on Ver. 5.01) Has anyone come across an issue where you plug into the customers network and after about 5 mins the system crashes? And then you unplug it and the system comes back? (Not even doing a power cycle) I plan to call NTAC in the morning, but not sure where to go with this one? This all stemmed from me troubleshooting a VM to email issue.

Thanks,
-Iron

NTAC able to give you any guidance?

Have only seen this at a Secondary location in a Netlink application. Primary never went down, but secondary location would crash if the customers VPN went down. System would not recover until the network cable was unplugged.

Hi conxtel,
That also is a weird issue. For my issue, right now we are trying to transition this customer over to our company. NTAC won't assist us until we get a Associate Dealer change in place. I'm afraid I won't have updates until then. But I will report back.

Thanks,

Have you looked at System Alarms?
We're dealing with an issue involving constant "IP Collisions". Once in a while it overwhelms the DSP's (we think) and there is no talk path for about 5 minutes then it rights itself.
Something to do with Cisco Discovery Protocol.

Hi PFD45,
So we finally got the "Associate Dealer" change request in, and it they are now with us! BUT, alas I did not need to call them. I know the first thing they were gonna have us do is get it to the latest revision. So I took it from 5.01 to 11.00. Once I did that and plugged them in, started working with no issue.

I know.....I'm also like, What in thee "H"?!

So far they've ben up for over a week with no complaints.

Thanks,
-Iron

Hi PFD45,
Where you able to fix the IP Collisions and find the problem?
I'm having the same issue at a site too.
Anything would help!
Thanks

The closest that I've come is to use DIM to pull the arp cache from the 8100.
Apparently this box doesn't like seeing quad zero's for an IP address and Cisco Discovery Protocol generates that somehow.
The one in red belongs to Cisco. I showed it to our network administrator and he said "your box shouldn't be able to see that".
So I've opened a can of worms but haven't sorted it out yet.
I'll post if I get any closer to a solution.
