The release also introduces Catalyst 8000v as a supported platform (closely related to CSR 1000v, with VXLAN temporarily disabled). A unified VM startup readiness script replaces multiple ad-hoc solutions, a new --ready option is added to netlab initial for checking device readiness without configuring them, and a KeyboardInterrupt handler is implemented for all long-running netlab commands. Upgrade via pip3 install --upgrade networklab. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I upgrade netlab to the latest version? Upgrade netlab by running pip3 install --upgrade networklab. This installs the latest release from PyPI, including all new platform support and bug fixes. _Network engineers tracking netlab releases and new platform support find the latest updates on daily.dev._ ### Does netlab 1.8.4 support Catalyst 8000v and what features are available? netlab 1.8.4 adds Catalyst 8000v support. It is closely related to CSR 1000v, so most CSR 1000v features are also configurable on Catalyst 8000v. VXLAN support is temporarily disabled because CSR 1000v VXLAN configuration was accepted but did not work on Catalyst 8000v. MPLS/VPN support has not been tested. _Engineers evaluating Cisco virtual platforms for netlab labs can track feature gaps like these 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 --- Tags: [#networking](https://daily.dev/tags/networking) [View this post on daily.dev](https://daily.dev/posts/netlab-1-8-4-vrnetlab-containers-catalyst-8000v-ipspace-net-blog-amgs4x0jq) ```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":"netlab 1.8.4: vrnetlab Containers, Catalyst 8000v « ipSpace.net blog","url":"https://daily.dev/posts/netlab-1-8-4-vrnetlab-containers-catalyst-8000v-ipspace-net-blog-amgs4x0jq","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/netlab-1-8-4-vrnetlab-containers-catalyst-8000v-ipspace-net-blog-amgs4x0jq"},"datePublished":"2026-08-11T08:51:48.064Z","dateModified":"2026-08-11T08:53:18.413Z","description":"netlab 1.8.4 adds vrnetlab container support for all devices supported by both vrnetlab and netlab, including CSR 1000v and Nexus 9300v.
