The headline addition is `netlab clab tarball`, which packages a containerlab deployment (including startup device configurations) into a tarball that can be used without netsim-tools installed. Other additions include `fetch_config` support for SR Linux and SR OS devices via `netlab collect`, new `--tar` and `--cleanup` options for `netlab collect`, a `--cleanup` option for `netlab down`, management VRF support in Arista vEOS and Juniper vSRX build recipes, and a switch from `ansible_network_os` to `netlab_device_type` for selecting configuration templates — enabling pseudo-devices like ExaBGP without requiring a real OS identifier. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How can I create a containerlab tarball with startup configs using netsim-tools without requiring users to install netsim-tools? The `netlab clab tarball` command (added in netsim-tools 1.1.4) generates a tar package that includes the containerlab configuration file with pointers to startup device configurations. Users of the resulting tarball can deploy the lab with containerlab alone, without needing netsim-tools or Ansible installed. The workflow is: run `netlab up` to configure the lab, `netlab collect` to gather configs, then `netlab clab tarball` to package everything. _Network engineers building shareable virtual labs track netsim-tools releases like this on daily.dev._ ### How do I collect device configuration from SR Linux or SR OS devices using netsim-tools? SR Linux and SR OS gained `fetch_config` action support in netsim-tools 1.1.4, contributed by Jeroen van Bemmel. After this release, `netlab collect` can retrieve the current running configuration from these Nokia devices, enabling mixed-vendor labs that combine Arista cEOS and SR Linux nodes with a unified config collection workflow. _Those running multi-vendor virtual labs can follow netsim-tools updates on daily.dev._ ## Similar posts on daily.dev - [netlab 26.09: Syslog, More DNS, Netmiko « ipSpace.net blog](https://daily.dev/posts/netlab-26-09-syslog-more-dns-netmiko-ipspace-net-blog-7hzbp4smq) · ipSpace.net Blog · 0 upvotes · 0 comments - [netlab 26.10: SRv6, More Netmiko « ipSpace.net blog](https://daily.dev/posts/netlab-26-10-srv6-more-netmiko-ipspace-net-blog-1cocu1zdt) · ipSpace.net Blog · 0 upvotes · 0 comments --- Tags: [#networking](https://daily.dev/tags/networking), [#ansible](https://daily.dev/tags/ansible) [View this post on daily.dev](https://daily.dev/posts/netsim-tools-release-1-1-4-ipspace-net-blog-zg1yn1oxr) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"netsim-tools Release 1.1.4 « ipSpace.net blog","url":"https://daily.dev/posts/netsim-tools-release-1-1-4-ipspace-net-blog-zg1yn1oxr","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/netsim-tools-release-1-1-4-ipspace-net-blog-zg1yn1oxr"},"datePublished":"2026-08-11T08:53:36.590Z","dateModified":"2026-08-24T06:52:41.887Z","description":"netsim-tools release 1.1.4 introduces several new features driven by community contributions.
