Post upgrading the SRX to 22.2R3, ethernet switching is not working across intra VLAN subnets access.
Ping between 2 intra vlan ip-address does not work.
ping between intra vlan ip-addresses stop working post upgrade of the SRX.
The traffic between intra vlan will stop working when STP is configured on the associated interface and ethernet switching mode is enabled on the device.To check STP configuration:protocols { l2-learning { global-mode switching; } rstp { interface all; }
To check ethernet switching mode: > show ethernet-switching global-information

Workaround is to disable spanning-tree protocol, further reboot the SRX for the change to take effect.
