Hi All, Will this cause the issue? Stack Member 2 Port 48 IP: 10.5.4.2 MAC: 02:02:0a:05:04:02 VLAN: 404 Stack Member 5 Port 47 IP: 10.5.4.2 MAC: 02:01:0a:05:04:02 VLAN: 404 The same IP address with a different mac address, from what I know it will cause a loop but I don't see any logs showing up in Meraki. Only the Palo Alto Firewall is getting 802.1q packet drops.

Hi, the uplink to PA is this port.

This is the config in Meraki Stack 2 Port 48 Stack 5 Port 47

The configuration is as follows for both ports. interface GE0/x description 32-063 switchport access vlan 464 switchport mode access switchport voice vlan 600 spanning-tree portfast Previously the load-balancer VLAN is using 464, on the new meraki, it is now using 404

Hi All, Just need to get some advice regarding this issue, after the Meraki stacks were installed. The Palo alto started getting flow_rcv_dot1q_tag_err from the same VLAN and Client. I checked the dashboard and it shows the following Stack Member 2 Port 48 IP: 10.5.4.2 MAC: 02:02:0a:05:04:02 VLAN: 404 Stack Member 5 Port 47 IP: 10.5.4.2 MAC: 02:01:0a:05:04:02 VLAN: 404 The customer says that they never encountered packet drops in the firewall before using old switch stacks (not meraki).
