MX68 Failover on Same Device

Hello there,

 

I am seeing odd failover behavior or really no failover at all happening.  I have a MX68 with WAN1 working fine.  I have a MG52 and connected it to WAN2.  The device shows up, connected, and in a Ready state.  Both green LED.  When I pull the WAN1 cable from the MX, no failover happens?  The LED state goes from both Green on WAN1-2 to NO LED color at all on WAN2.  Failover does not work.  Plug back in WAN1 and connection is working again.  I have toggled from Graceful to Immediate, and no change in behavior?  Any ideas?

WAN failover is automatic, have you tested the MG link beforehand to make sure it is working properly?

Basic Internet testing through the MG52 was tried on a laptop several days before we actually connected it to the MX today.  It was just the MG52 and laptop and we had no issues getting to the Internet.

Is WAN 2 receiving the IP correctly? Did you use the MX dashboard's test tool to see if the internet is actually working via WAN 2?

WAN2 shows a public IP from the sim provider.  It is in a Ready state.  From the Tools section on the MX, ping to 8.8.8.8 works fine selecting Internet2.  Trace route dies as does MTR selecting Internet2.  From the Tools section on the MG, the DNS Lookup seems to look fine and ping to 8.8.8.8 works.

Just out of curiosity, have you tried rebooting your MX?

If you've already tried, I suggest you open a support case.

The behaviour you're seeing certainly isn't expected if you're physically removing the WAN 1 cable.

It should failover very quickly (usually 1-2 ping drops).

I have this setup at many sites, and it works relatively flawlessly.

 

Given the responses above, it sounds like you've done quite a bit of testing already.

I suggest opening a support case.

Hello,

I opened a case a few days ago.  They suggest a reboot of the MX.  Well tonight I am upgrading the firmware and the reboot will take place as well.  I will be testing this again tomorrow hoping for better results.

Update:  Reboot and or firmware upgrade solved the issue.  More than likely the MX just needed a reboot.  Lost 1 ping on failover.  Thx
