When I manually disconnect a switch, the system quickly detects SNMP and ICMP errors, but then the node status becomes UNKNOWN, and then the polling of that node seems to stop, and the SYS_NODE_DOWN event cannot be generated,  the node status cannot become CRITICAL, please tell me under what circumstances the node status will become UNKNOWN and how to solve this problem, thanks a lot!

Thank you very much for the pointers!

Thank you very much, but  if  manually exclude the child nodes, it is too much trouble,  can there be any rule than can  automatically adapte  to it?

I would like to ask the expert a question: if an aggregation device is disconnected, all the devices under it will be offline, and each device will send an alarm message at this time. How can we make sure that only the top device performs the action of sending alarm message, and the lower part relies on the device not to send alarm message?

Thank you very much for your advice! This is really the most powerful network manager I have ever tried!

I found that only the physical interface can get the peernode, but seems the value fetched by the vlan interface or bridge-aggregation interface is null, how can I get all the directly connected devices?

Okay，thank you very much！！

A few questions about network map：
1、How to hide the link label in the network map by default, or the default abbreviation, such as gigabitethernetg1/0/1 can be shown as g1/0/1?
2、The default network topology will show subnets, can be canceled?
3、If I want to show only the devices directly connected to the root node in the network topology, how to filter it?
I look forward to your guidance, thank you very much!

ok,thank you very much!!

How can I filter the auto-discovered devices through snmp community, the current script is
sub main()
{
    transport = $1->createSNMPTransport(161,"stonewell2000");
    if(transport != null)
    {
        sysname = transport->getValue(".1.3.6.1.2.1.1.5.0"); 
        if(sysname != null && sysname !="" && sysname !=" ")
        {
            return true;
        }
    } 
    return false;
}

But the script reports an error, suggesting that if $1 is replaced by $node or $ NewNode , it will also report the same error, please ask the experts for guidance, thank you very much!
