NQE Discussions

I want to feed a list of ~5K IP addresses into forward and track the IP down to whatever info is available (device interface, standby address, device interface neighbor, host).I have two functions that build the lists of records that I need to join by ip address.FromCSV  (~5K records) and allKnownIps  (~200-300K records)What is the most efficient / elegant way to join essentially join these tables?I tried to build the smaller list first and then build the known IP list only if there is a match and then ran a nested loopcsvListIPs = (foreach ip in FromCSV select ip.ipAddr);// List of ~5K IPsallknownIpList = (foreach knownIp in allKnownIps where knownIp.ipAddr in csvListIPs select ip);//Filter for only known IPs in CSVlistforeach knownIp in allknownIpListforeach csvIP in FromCSVwhere knownIp.ipAddr == csvIP.ipaddrselect{};So I have

I finally managed to write a useful NQE query with no help. Yay! This query lists all of the loopback interfaces and their IP addresses. I tested it, and it works. But I am curious if there is a more efficient or elegant way to enumerate the IP addresses. Seems to me a little clumsy. getSubIfaceIpInfos(iface) = foreach subIface in iface.subinterfaces foreach subnet in subIface.ipv4.addresses select subnet;foreach device in network.devicesforeach interface in device.interfaceswhere interface.loopbackModelet ifaceSubnets = getSubIfaceIpInfos(interface)select { deviceName: device.name, interfaceName: interface.name, ipAddress: foreach subnet in ifaceSubnets select ipSubnet(subnet.ip, subnet.prefixLength)} 

I am trying to use a where filter like so: where (a && b) || cPrettify keeps removing the parenthesis. Doesn’t this mess with the order of operations?

I am trying to use the harvest the INVENTORY device state file but target the Description field, but I am unsure on on how to do that so that I can select it. I have the following:import "External/Juniper-EoS";foreach device in network.deviceswhere device.platform.vendor == Vendor.JUNIPERlet outputs=device.outputsforeach command in outputs.commandswhere command.commandType == CommandType.INVENTORYlet platform = device.platformwhere isPresent(platform.model)foreach part in platform.componentswhere isPresent(part.serialNumber)select { deviceName: device.name, model: platform.model, part: part.serialNumber, violation: if part.partId in juniper_eos then true else false} 

Is there a way to add an "or" statement in a NQE? We are checking IOS versions against a model and Cisco says it can be this or that but the NQE we have looks like it's looking for both and throwing a false positive.

Is there a way to filter out duplicate MAC entries to get a unique MAC address count? Using the standard NQE library query under "L2 -> Mac Entries" returns every VLAN and device a MAC entry is seen on, skewing the results as shown in the example image.
