Re: DHCP Snooping issue after 12.0.13.8 Upgrade

Arnaud_D · ‎2021-12-28

Hello people,

I just upgraded my M4300-52G to the last firmware version and as soon as the switches rebooted none of my devices were able to get an ip from my dhcp servers. Until I turned off DHCP Snooping.

I checked my conf, but Trust Mode was correctly enabled on the Lag that goes to my dhcp servers's switch (and the 4 ports within the LAG).

It was working perfectly before the upgrade and I did no change to my conf, so for me the issue comes from the new firmware

DHCP SERVERS<==>SWITCH (LAG 1)<=========>(LAG 3) M4300-52G

No dhcp snooping DHCP Snooping On, LAG3 Trusted.

Does anyone else has/had this issue ?

Thanks for your feedback 😉

Hello,

Nobody else has this issue since the upgrade ?

I don't have a spare M4300 to do tests to confirm it's caused by the new firmware

Thx for your time 🙂
