Sits below 5% and occasionally will go to about 60% under high load. The cluster indexes shown in the last two lines of the command output are the operating cluster indexes that reflect how the cluster units are actually operating in the cluster. Since you typically use these tools to troubleshoot, you can allow them in the security policies and on interfaces only when you need them, and otherwise keep the ports disabled for added security. What traceroute can tell you Ping and traceroute have similar functions—to verify connectivity between two points. Note: The default configuration is to have all protocols enabled. Since I also send logs to FortiCloud free for 7 days worth of logs! This article also contains information about sorting the information displayed by the command and about how to use the information displayed by the command to identify the process to stop. I update firmware, install config, and put in place.
It is important to know what interfaces are part of which forwarding domains as this determines which interfaces can communicate with each other. You can stop and restart it at any time. It might also be that the interface is disabled, or has its Administrative Status set to Down. Nothing - still at 99%-100%. Each additional line of the command output displays information for each of the processes running on the FortiGate unit. Master selected using Shows how the primary unit was selected the last four times that the cluster negotiated.
If some processes use all the available memory, other processes will have no memory available and not be able to function. The command also displays information about each process. They overnighted a new firewall to me. Debugging the packet flow requires a number of debug commands to be entered as each one configures part of the debug action, with the final command starting the debug. Normally this should not happen as it shows the FortiGate is overloaded for some reason. Each line includes a time stamp and the criteria used to select the primary unit.
This is an added troubleshooting feature that can be useful in determining why particular services, such as email or web browsing, may not be working properly. Last week I drove 2. With verbosity 4 and above, the sniffer trace will display the interface names where traffic enters or leaves the FortiGate unit. And we have 27 users. The host names of the FortiGates are 5001d-slot4 and 5001d-slot5. The network settings include: Interface settings If you can access the FortiGate unit with the management cable only, the first step is to display the interface settings.
If this cluster was operating with virtual domains enabled, adding virtual cluster 2 is similar to adding a new copy of virtual cluster 1. If one of these processes consumes nearly all the resources. Thank you both for your replies. For example, changing the ports used to maximize accelerated traffic makes a significant difference. If you have determined that network traffic is not entering and leaving the FortiGate unit as expected, debug the packet flow. If you want to test if it is a hardware problem or not, you can disable all the policies and keep one for yourself and test the internet. If so, is it using the correct server, credentials, and interface? This is a secure option as no unscanned traffic is allowed to pass.
However, ping can be used to generate simple network traffic to view with diagnose commands on the FortiGate unit. As far as I can gather, this process handles system logging functions. The following information includes troubleshooting and best practice information. I checked over everything and upon console connection to the firewall found it throwing all kinds of crazy errors. Also when you use the execute ha manage command you select a cluster unit to log into by entering its cluster index. When this happens, it often shows up as intermittent Internet connectivity. This means the actual and operating cluster indexes of the cluster units do not match.
You may also see a line titled Max Concurrent Connections for each protocol. Checking these criteria could result in selecting a cluster unit without the highest serial number to operate as the primary unit. This is usually true, but some applications may have problems with this and start complaining about either not having or being able to open a session. Model The FortiGate model number. How to check hardware connections If there is no traffic flowing from the FortiGate unit, it may be a hardware problem.
By default, all interfaces are in group 0. When increasing logging levels, ensure that alert email is configured and both disk usage and log quota are selected. Ok this is driving me crazy. If Link Status is Down, the interface does not work. Includes whether the interfaces are up or down, how much data they have processed as well as errors found. Setting it to idledrop will drop connections based on the clients that have the most connections open.
If virtual domains are enabled the cluster has two virtual clusters. Checking sessions in use To make troubleshooting this type of problem easier, sessions are broken down by which protocol they use. How to check the bridging information To list the existing bridge instances on the FortiGate unit, use the following command: diagnose netlink brctl list Sample output: diagnose netlink brctl list list bridge information 1. This will display the next three packets on the port1 interface using no filtering, and using verbose level 1. For instance, you may want your oracle or citrix or telnet or ssh sessions to last longer if no activity is seen.
I want to see if anyone else has had similar issues, as well as get some advise on where to go next. The modem diagnose output should not contain any error on the way to initializing. By default both sets of cluster indexes are the same. To support this, note that the maximum session count for each protocol is the same. If virtual domains are enabled, vcluster 1 displays information for virtual cluster 1. The extrange thing is that the fgt was working perfect until last week that i saw the following mesage: 2009-01-02 12:17:47 Fortigate has reached connection limit for 476 seconds 2009-01-02 12:09:42 Fortigate has reached connection limit for 542 seconds 2009-01-02 12:00:31 Fortigate has reached connection limit for 541 seconds 2009-01-02 11:51:20 Fortigate has reached connection limit for 417 seconds 2009-01-02 11:44:12 Fortigate has reached connection limit for 317 seconds And today the cpu usage in 99%. Depending on their workload, each process will use more or less as needed, usually more in high traffic situations.
