Meraki

Hello team, I have a tenant with both MS130 and C9300 with Meraki firmware switches. The C9300L-48P-4X stack (2 appliances) periodically loses network connectivity. All switches are layer 2 only; the stack keeps switching packets, downstream devices (such as one MS130) work just fine and can be managed by the dashboard. Yet the C9300 stack doesn't respond to ping and of course can't communicate with the dashboard. a hard reboot solves the issue, then after a week or so it loses once again IP connectivity. It happened three weeks in a row, with no discernible pattern for time. These 2 are the only Catalyst switches in the tenant; all the MS130 and all Access Points in the tenants show no issues. All devices have static IPs on the same subnet. can you please suggest a few troubleshooting steps for this issue? thanks in advance Fabio

Hello team, I have a setup with two uplinks (WAN1 and WAN2), from 2 different service providers, connected to an MX250 (18.211.6) appliance. Both ISP routers are connected to a switch and through different VLANs they get to MX fiber ports. The setup is as Load Balancing 50/50 (the two lines are both 1Gbps) with no relevant flow preferences. trying a failover test, powering off one router at the time, I can see that failover from WAN1 (primary) to WAN2 takes about 20 to 30 pings (which is a lot) whereas failover from WAN2 to WAN1 is extermely fast (1 or 2 pings lost at most). is this expected? Does it take more for the MX to "give up" on the Primary WAN even in symmetrical load balancing? Or am I experiencing some kind of issue that needs to be adressed? thanks F.
