![]() ![]() A screen capture from Object Details of the switch.I used the following reference to get those OIDs: An SNMP walk of the 3 VLANs and typical OIDs used for mapping the MAC table to switch ports.typically the gigabit ports are connecting to servers and other nodes in the same rack. We always use one of the Ten Gigabit ports as a trunk to the other switches. I picked a simple 24 port gigabit switch, that has an additional 2 ports of ten-Gigabit. I've attached the following files to demonstrate the problem. Seeing that it indirectly connects to a root switch in the core isn't helpful since all my devices connect to one of the two root switches. Is there are way of configuring NetXMS to store all the addresses? I would really like to be able to use the "Find switch port" feature on an object to see the local port it is connected to. So, I'm puzzled at why the static addresses are missing. When I researched cisco literature, I couldn't even find a reference for using SNMP to look at whether an address is static or dynamic. Strangely when I snmpwalk the switches, all the mac addresses appear and I don't see anything obvious that would distinguish between static addresses and dynamic addresses. Apparently, even though those addresses are "learned", Cisco classifies them as Static. This prevents someone from plugging in a foreign device that we don't know about. We use Cisco's security features where it learns what mac addresses are directly connected to a port and only lets those addresses on that port. In researching the problem, I've determined that NetXMS is only storing "dynamic" MAC addresses. It always reports that a given node is indirectly connected to a remote switch. If I try to find a switch port, it never reports a direct connection. ![]() The problem I'm running into is that NetXMS seems to only be aware of some of the MAC addresses on the switch. I am on NetXMS version 1.2.17 at this site. NetXMS is using the CATALYST-GENERIC Driver so it appears that the switches are being recognized. ![]() I have a site that has about 20 Cisco 2960S switches and a couple Cisco 4900M switches that I have NetXMS monitoring. ![]()
