Interface disable longer then lease will then not when re-enable work

PeterUK

USG FLEX 200H V1.21(ABWV.0)

P3 config as a WAN set to DHCP connected to DHCP server with a lease for 3 minutes.

When you disable P3 WAN for 5 minutes then re-enable the WAN does not work.

Workaround unplug the Ethernet and back in or change port Negotiate to trigger and DHCP restart.

Hi @PeterUK,

We have addressed this issue and investigating it now. I will update you once I get further information.

Hi @PeterUK,

This issue has been fixed. We will add this fix to the future firmware release.

PeterUK

So tested the firmware you sent me (thanks) it works but seems to take a long time for the interface to re-enable and start working again.

Hi @PeterUK,

Do you mean the period between you enabling the port and the WAN port having traffic to pass through? Could you help to confirm how long it is?

PeterUK

Yes you disable it for like 5mins then enable then takes a bit of time to get a a IP and start working again not a big problem but you would think it take like 10 seconds

PeterUK

So one test it failed to get a IP over 3 minutes another test shows after enabling WAN takes over 1 minute 30 seconds before it gets a IP and starts working and another test in 60 seconds.

Hi @PeterUK,

Thanks for your update.

We need your help with the investigation:

1. Collect the diag info after testing and mark the test time. Then we can check the syslog to clarify the process.
2. It would be helpful if you could collect the DHCP packet at the same time. It can help us to clarify the whole timeline during the process.
