Re: CP3 Ethernet Issues


 

¿ªÔÆÌåÓý

Ethernet watchdog is virtually always a network issue, specifically broadcast/multicast storms.

Do you have AVoIP devices (e.g. NVX, Dante, etc. on the same VLAN)? If so make very sure that IGMP, etc. is properly configured on all switches.

?

If I recall correctly the dwRxPacketReceived values indicate that it¡¯s receiving more than 4400 packets per second which is not typical.

?

If you fire up wireshark on a hardwired connection on the same VLAN it should be largely quiescent ¨C some ARPing and other housekeeping traffic at? trickle ¨C if you are seeing a constant stream from one or more IPs/MACs, there¡¯s hard evidence of the problem I¡¯m describing.

Hi Guys,

Even I facing the same issue in couple of places, the CP3 errlogs is flooded with watchdog errors. I don't know how to resolve this. When I asked help? from the crestron true blue support they just say its the network issue, the network is getting flooded with traffic. I don't think that's the case because the sane issue cannot be happening in all my clients place at the same time.

FECTimer: Exceeded Receive Packet Trip Count, dwRxPacketReceived: 4408 in 1000 milliseconds

FECTimer: Ethernet disabled by watchdog

FECTimer: ETH RX re-enabled by watchdog

It would be great If anyone could help me out in this issue.
