I am trying to get the BGP advertised and received prefixes for Arista EOS and Cisco NXOA devices. I tried the below two queries and they only work for IOS and IOS-XE. devicesBGP Received routes ----------------------------------------------------------foreach device in network.devices// where device.name == "jcdwans01"where isPresent(device.bgpRib)let bgpRib = device.bgpRibforeach afiSafi in bgpRib.afiSafisforeach neighbor in afiSafi.neighborswhere isPresent(neighbor.adjRibInPost)let adjRibInPost = neighbor.adjRibInPostselect {  deviceName: device.name,  platform: device.platform.os,  afiSafiAfiSafiName: afiSafi.afiSafiName,  neighborNeighborAddress: neighbor.neighborAddress,  routesCount: length(adjRibInPost.routes)}BGP advertised routes -foreach device in network.deviceswhere isPresent(device.bgpRib)let bgpRib = device.bgpRibforeach

This is both incredibly amazing and absolutely frightening. The cat is extremely out of the bag now.Boston Dynamics put a generative AI into the robot dog Spot. And there are different personalities.

You can now attach EC2 interfaces to multiple different VPCs in AWS: https://aws.amazon.com/about-aws/whats-new/2023/10/multi-vpc-eni-attachments/ The implications of this are pretty huge - previously to control access (with a firewall, etc) between VPCs you needed to use a Transit Gateway, generally associated with a centralized applicance via a Gateway load balancer.  This solution is great and scales very well, but its probably overkill for smaller environments. What if you only have 2-4 VPCs?  This solution would work great - simple attach your NVA interfaces to different VPCs and modify your route tables accordingly.  This eliminates the cost and complexity of TGWs, keeping all the performance benefits. What use cases can you see for this new functionality?  Off the top of my he

WHO DARES TO INVESTIGATE THE DARK PRESENCE WITHIN THE NETWORK DURING AN AUDIT? Network modeling illuminates the dark corners of your network, so you don't have to be scared anymore. No boogeyman can derail your network audit because the 'digital twin' models all of your network devices, even the cloud, with mathematically-accurate precision. It’s the single-source of truth trusted by the world's largest networks. It’s not dark magic — it's Forward Enterprise. 

Is it possible to use a SSH jump server to log into a Telnet server, and then from there log into each of the devices?

In Part 1 we introduced several techniques for dealing with semi-structured data to parse a Juniper Inventory. In Part 2 we will leverage a few more techniques to parse a more complex output. 1. Let’s setup our test by grabbing the output from the “show chassis hardware” command. remember to use the multi-string block delimiter “””We have 5 columns Item, Version, Part number, Serial number and Description, but we are only interested in three: Item, Serial number and Description. output = """Hardware inventory:Item Version Part number Serial number DescriptionChassis JN2221837ABC MX960Midplane REV 03 710-013698 TR0123 MX960 BackplaneFPM Board REV 03 710-014974 JZ1111 Front Pan

Sometimes you need to parse out information that is not in the NQE data model for various reasons. It maybe device specific information that is not generalizable across vendors, or not generally useful in dataplane analysis but maybe important for operations. Importing this data is beyond the scope of this post but you can read more about it here: Getting Custom CommandsFirst, I am going to demonstrate how you build up your parsing chops by leveraging a testing approach to NQE, then will demonstrate how this can be applied to your collection data. Setting up your testing. We need to represent the data that our custom command will import into the snapshot. We can represent this by setting a variable to a multiline string using the delimiter ”””

This is a check I wrote to check BFD Status on Arista and IOS-XE as a single combined query. Unfortunately, I can’t change the name of the title to include Arista && IOS-XEscreenShot /*** @intent BFD State Arista & IOS-XE* @description Add Command 'show bfd neighbors || peers' and report status - apply to EOS and IOX-XE Devices**/EOS_BFDPattern = ```{DstAddr:ipv4Address} {MyDisc:number} {YourDisc:string} {Interface:string} {Type:string} {LastUp:string} {LastDown:string} {LastDiag:string} {State1:string} {State2:string} {State3:string} {State4:string} ```;iosXE_BFDPattern = ```{ip:ipv4Address} {LD:string} {RD:string} {State:string} {Int1:string}```;// Define EOS FunctionArista_BFD = fo

 Many customers often ask me about digging into data, especially when it involves sifting through device status or custom command outputs. Sometimes, it's a piece of cake to handle because the data is nicely structured, but other times, it's like solving a puzzle. Just last week, I was helping out a customer who needed to extract security policy data from their enforcement points to keep tabs on various compliance matters. The data they had to deal with was all over the place – lines of varying lengths, multiple strings scattered within the lines, and positional changes for the data we needed.This got me thinking, and I wanted to share some techniques for handling these tricky data chunks. I can't share the exact customer query with you, but I've thrown together a sample query to show one way of tackling this.Imagine you've got data like this:"Don't teach me how to extract stuff with IP address 10.1.1.1 and float 10 from string."

Audit our DNS configuration on Arista Devices and Cisco Devices - Would like to be able to combine the script as a single check, and started it (Second Code Script), but it’s not working yet, I need a little tutoring. /** * @intent Audit DNS Configuration on Arista * @description Searches through the running configuration for a pattern match. */DNS_Standard = ["name-server 1.7.7.7 & 1.7.7.8", "dns domain net.xyz.com ", "ip domain lookup source-interface Loopback0"];AristaPatternDNS =```ip domain lookup source-interface Loopback0dns domain net.xyz.comip name-server vrf default {ipv4Address} ip name-server vrf default {ipv4Address} ```;/* Select a list of devices by vendor */foreach device in network.deviceswhere device.platform.vendor == Vendor.ARISTA || device.platform.os == OS.ARISTA_EOSlet outputs = device.outputsforeach command

I’d like to use FN APIs to integrate with Splunk and SIEM / Security systems. Has anyone else done this?

Are there any character restrictions for tags? I would like to use ’ : ‘ in a tag as a namespace but want to be sure there won't be any caveats. I don't see anything in the docs.

Is there a reference to building new dashboards using NQE derived values as inputs?

How do you create a custom SSL certificate for the fwd web interface?

Hello Team, we have an NQE thatsearches all L2 switches obtains each interface status obtains speed obtains sfp informationfor all ports in up state. So far, we have the following:foreach device in network.devicesforeach item in device.platform.componentswhere item.partType == DevicePartType.TRANSCEIVERlet interface = (foreach interface in device.interfaces where isPresent(findInterface(device, item.name)) where interface.name == findInterface(device, item.name).interface.name select interface)where length(interface) == 1let int = min(interface)select { deviceName: device.name, iface: int.name, speed: int.ethernet.negotiatedPortSpeed, partType: item.partType, partName: item.name,} Is there a way we could extract and add the below underlined in BLUE as additional col

Is there a way to connect external sources to a postgres database or consume a postgres DB backup? We cannot collect directly from type 1 encryptors but we can get a backup of the encryptor manager DB

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?

For Path Search Ranking, will devices that have a more specific subnet always rank higher than devices with a less specific subnet as the ingress device for a path?

We want to run two clusters in HA Active/Standby. We deployed one cluster yesterday and licensed it. We deployed the second cluster today. I am unclear on how we would license the second cluster. I assume we need a second deployment, but can I apply the same license to that new deployment, or would it require a new license as well?
