WAN link manger fails to test after link restore

Tomorrow's challenge, makes good activity, weather forecast is rain, rain, rain.

I will copy today'y result before starting testing tomorrow and sent it to you in PM. Should not having any parameters for port allowed the capture of all traffic?

Ian

TCPDUMP which you have taken earlier will only capture traffic destined to host 2001:4860:4860::64. DHCP6 traffic won't have this as source or destination so it won't be capture.

On a second thought, I suggest to save pcap on appliance itself so that it can be reviewed later. Please use following command (verified on your appliance) which will save pcap file in /var/sanket-logs folder.

XG115w_XN03_SFOS 19.5.0 EAP1-Build144# tcpdump -n host 2001:4860:4860::64 or port 546 or port 547 -vv -b -w /var/sanket-logs/icmp6_dhcp6.pcap

Okay, will do.

Hi Sanket,

thinking about the command line, it will not produce the results you are after because the IPv6 address is a google one and not a telstra network server.

Ian

I sent you a PM.

Hello Ian,

After doing investigation from the logs and pcaps gathered on your setup, it sounds like defect.

There might be some race condition happening between DHCP IPv6 address assignment and gateway.

Issue is being tracked against NC-108057 internally and we will try to fix it as soon as possible.

Meanwhile only workaround in such scenario is - reboot the appliance :-(

Thanks a lot for all your support and cooperation. And sorry for the inconvenience caused.

Regards,

Sanket Shah
