No failover on HA Cluster if Nic is in Error-State

Odi

Hello,

we are Using two SG 310 as a active / passive cluster.

Unfortunately we experienced that HA is not working.

Approximately once in a month we are loosing internet-connection.

The external WAN-Interface shows "ERROR" under "Link" and "UP" under "State"

Unfortunately the Cluster isn't switching to the other Node and the whole Office is cut from Internet.

If we turn the Interface off and on again, everything is working fine.

Rebooting the affecting Node will work too.

 

Did someone experince a similar behaviour.

We have to sort this problem out and support is not very helpful in this case

    Which cluster state you see.

    If there is a "unlinked" state the interface-down don't result in cluster failover.

    the problem is that ther is no "interface down". Instead there is a "error" state on the WAN Interface.

    cluster is working fine. If i reboot the affected node then  the second node will take over immediately.

    Often the "error-state" we see, if the speed & duplex settings not the same at router and SG.

    For example ... you could not have "auto" at one side only.

    The true reason for an 'error' state is that it failed the 'uplink monitoring' conditions. 

    Basically the UTM cannot reach whatever hosts on whatever protocols that it uses to check if it has internet access. The 'error' state itself is not a problem but what caused it is. 

    Do you reboot both nodes when this happens or just one?
