VLAN cannot talk to sophos firewall
Hi
I have an issue after rebooting the switch and Netgear M4300 not able to talk to the
firewall. the switches are connected via Port 13 port 14 configured as a LAG, is that any one have the same experience? Can share the solutions thank you.

What was done before the reboot then?
The LAG must be configured for each VLAN [T]agged, optionally one VLAN can be [U]ntagged if the LAG PVID is set to the same. This does logically apply ot the Sophos side, too.

We never change any configuration.
I called netgear support and they advised me to update the new firmware which fixed the LAG issue. After update firmware reboot again and LAG interface back to normal can ping to sophos firewall. but unfortunately cannot ping downstream. I tried a cool restart again (2nd time) downstream, able to ping upstream but the firewall lost communication, tried restart 3rd time now both not working (firewall and downstream).New firmwareEnhancements:
- Assigns the service port (OOB port) IP address to 0.0.0.0 by default. As a fallback, if the service port is connected and the DHCP request times out, the switch assigns the IP address to 192.168.0.239.
Bug Fixes:
- Fixes an issue where the switch can go into a restart loop.
- The stack is unstable after a restarted stack member comes back online.
- The SFP link between the S3300-28X-PoE+ and XSM4348S switches is not restored after the S330028X-POE+ is restarted.
- The DiffServ wizard in the UI doesn't work.
- When the 10G/1G SFP module is used in an SDVoE environment, video tearing is observed.
- After a cold restart of the M4300-24XF stack, communication over an LACP LAG fails.
- Querier is not set when the IGMP-plus is configured for VLANs other than VLAN1.
- When using an FQDN to access the switch or stack, the switches lock up or restart.
- When a stack contains the M4300-52G, stack links experience issues with multicast load-balancing.
- Fixes an issue that caused intermittent crashes in certain environments.
- Stack ports of the switch don't work with DAC cables.
- 40G stack links are not stable with QSFP BiDi modules.
