Overview
Bridge Direction alert 'Bridge may be connected incorrectly' is an alert that is triggered when the number of packages passing the bridge and intended for the internal subnet, is bigger on the WAN side than on the LAN side of the bridge.
Solution
Exinda uses the Management Interface (usually eth1) to identify the internal subnet. It assumes eth1 and the internal LAN are on the same subnet.
Exinda counts the packages intended for the internal subnet on both sides of the bridge (LAN and WAN interface). If the number of packages on the WAN side is bigger, it assumes that the LAN and WAN cables were not connected to the proper interfaces, hence generates this warning. This is because it assumes that the packages intended for the management interface (and not passing through the bridge) should be coming from the LAN side.
If the Exinda management interface is connected to a subnet after the WAN side, the packages intended for the Exinda management interface are adding to the total number of packages on the WAN side of the bridge, resulting in this warning. In such cases, the best option is to disable the alert.
Verify your Exinda setup is correct
To ensure that your Exinda is correctly set up, and these alarms should not be generated, follow these steps:
- Make sure it is not a connection problem by checking if the LAN-WAN cables within the bridge are connected properly: LAN devices are connected on the LAN side and WAN devices are connected on the WAN side.
- Go to
Monitor > Real Time. Check that the Internal IP column contains IP that belongs to the LAN while the External IP column contains external IPs properly (or if the cables are intentionally connected backward, then the IPs should also be listed in the opposite column - LAN IPs listed in the External IP column). - If you have VLAN assigned to Eth1 (management interface), consider moving it out of the LAN switch bridges to resolve the alert.
Disable the Bridge Direction Alert
If none of the previous steps helped, and you are sure your configuration is correct, you can disable the alarm.
- Disable the Bridge Direction alert in
Configuration > System > Setup > Alerts.
Testing
Check for the disappearance of the Bridge Direction alarm in Exinda's system dashboard. If you are still facing issues, reach out to the support team.
