This allows IT teams to identify issues at the network edge or in core locations quickly, and resolve them before users feel the impact.<\/li>\n<li><strong>Pre-check<\/strong>: Before implementing changes, you can use the ThousandEyes agent to monitor existing performance and ensure that everything is functioning optimally.<\/li>\n<li><strong>Post-check<\/strong>: After changes (e.g., firmware updates or routing adjustments), the agent helps verify that performance remains stable.<\/li>\n<\/ul>\n<\/li>\n<li>\n<p><strong>End-to-End Path Monitoring<\/strong>:<\/p>\n<ul>\n<li>Hosting the agent on a router enables <strong>end-to-end monitoring<\/strong> of the network path. This is crucial during network changes or upgrades, as the agent can detect whether new configurations have affected critical paths between branches or data centers.<\/li>\n<li><strong>Pre-check<\/strong>: Baseline the end-to-end performance before applying changes.<\/li>\n<li><strong>Post-check<\/strong>: Ensure that the modifications have not introduced <span style=\"text-decoration: underline;\"><strong>latency, jitter, or packet loss<\/strong><\/span>.<\/li>\n<\/ul>\n<\/li>\n<li>\n<p><strong>Proactive Problem Detection<\/strong>:<\/p>\n<ul>\n<li>With the ThousandEyes agent directly on a router, you can detect issues <strong>before they escalate<\/strong>. This is particularly important during maintenance windows when changes are being made. The agent allows you to monitor for <strong>early signs of degradation<\/strong> in the network.<\/li>\n<li><strong>Pre-check<\/strong>: Detect potential bottlenecks or problem areas before making changes.<\/li>\n<li><strong>Post-check<\/strong>: Validate that no new issues have emerged after updates or configuration changes.<\/li>\n<\/ul>\n<\/li>\n<li>\n<p><strong>Service Assurance and Application Performance<\/strong>:<\/p>\n<ul>\n<li>The ThousandEyes agent on routers can monitor not just network metrics but also <strong>application performance<\/strong>, especially when critical business apps traverse that router. This ensures that changes do not negatively impact application performance or cloud services accessed through the network.<\/li>\n<li><strong>Pre-check<\/strong>: Ensure application performance meets SLA before updates.<\/li>\n<li><strong>Post-check<\/strong>: Validate that applications continue to meet performance requirements post-change.<\/li>\n<\/ul>\n<\/li>\n<li>\n<p><strong>Impact Analysis of Network Changes<\/strong>:<\/p>\n<ul>\n<li>Routers are often the <strong>first and last hops<\/strong> for traffic entering and exiting your network. Placing a ThousandEyes agent here helps you assess how changes to <strong>routing policies<\/strong>, <strong>firewall rules<\/strong>, or other network adjustments affect overall traffic flow and performance.<\/li>\n<li><strong>Pre-check<\/strong>: Analyze how the current configuration impacts traffic.<\/li>\n<li><strong>Post-check<\/strong>: Compare the pre- and post-change performance to assess the impact of the changes on traffic flow and routing efficiency.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<p>\u00a0<\/p>\n<p>In summary, deploying a ThousandEyes agent on routers gives you <strong>end-to-end network visibility<\/strong>, <strong>proactive monitoring<\/strong>, and <strong>post-change validation<\/strong>, helping you maintain a stable and reliable network environment while making configuration changes with confidence. So can safely wear the Thousandeyes T-shirt with a slogan that says: &#8220;Go ahead blame the network!&#8221; \ud83d\ude05<\/p>\n<p>Keep in mind that Catalyst 8k is not the only platform where the Thousandeyes client can be deployed. The client is also supported on certain Nexus 9k, ASR, ISR 4k and Catalyst 9k devices.

This proves that our network monitoring setup with <strong>ThousandEyes<\/strong> on the <strong>Frankfurt-Edge<\/strong> and <strong>NewYork-Edge<\/strong> agents is functioning correctly and capable of detecting both normal and adverse conditions.<\/p><\/div><\/div><\/div><\/div><\/div><\/div>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-97a46c3 elementor-widget elementor-widget-image\" data-id=\"97a46c3\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a href=\"http:\/\/192.168.1.213:8088\/wp-content\/uploads\/2024\/10\/deploying_thousandeyes_on_catalyst8000v_009.png\" data-elementor-open-lightbox=\"yes\" data-e-action-hash=\"#elementor-action%3Aaction%3Dlightbox%26settings%3DeyJpZCI6MjUyNywidXJsIjoiaHR0cDpcL1wvMTkyLjE2OC4xLjIxMzo4MDg4XC93cC1jb250ZW50XC91cGxvYWRzXC8yMDI0XC8xMFwvZGVwbG95aW5nX3Rob3VzYW5kZXllc19vbl9jYXRhbHlzdDgwMDB2XzAwOS5wbmcifQ%3D%3D\">\n\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"414\" src=\"http:\/\/192.168.1.213:8088\/wp-content\/uploads\/2024\/10\/deploying_thousandeyes_on_catalyst8000v_009-1024x530.png\" class=\"attachment-large size-large wp-image-2527\" alt=\"\" srcset=\"http:\/\/192.168.1.213:8088\/wp-content\/uploads\/2024\/10\/deploying_thousandeyes_on_catalyst8000v_009-1024x530.png 1024w, http:\/\/192.168.1.213:8088\/wp-content\/uploads\/2024\/10\/deploying_thousandeyes_on_catalyst8000v_009-300x155.png 300w, http:\/\/192.168.1.213:8088\/wp-content\/uploads\/2024\/10\/deploying_thousandeyes_on_catalyst8000v_009-768x397.png 768w, http:\/\/192.168.1.213:8088\/wp-content\/uploads\/2024\/10\/deploying_thousandeyes_on_catalyst8000v_009-1536x794.png 1536w, http:\/\/192.168.1.213:8088\/wp-content\/uploads\/2024\/10\/deploying_thousandeyes_on_catalyst8000v_009-2048x1059.png 2048w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/>\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-67a64c6 elementor-widget elementor-widget-heading\" data-id=\"67a64c6\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h5 class=\"elementor-heading-title elementor-size-default\">Summary<\/h5>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0718714 elementor-widget elementor-widget-text-editor\" data-id=\"0718714\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>In this blog post, we explored <strong>application hosting on Catalyst routers<\/strong>, specifically focusing on deploying <strong>ThousandEyes<\/strong> on a <strong>Catalyst 8000v<\/strong> in a <strong>Cisco Modeling Labs (CML)<\/strong> environment. We walked through the deployment process, from enabling <strong>IOx<\/strong> services to installing and configuring the ThousandEyes agent. After setting up the test environment, we created an <strong>Agent to Server<\/strong> test between <strong>Frankfurt-Edge<\/strong> and <strong>NewYork-Edge<\/strong> agents to monitor network performance.<\/p><p>To make things more interesting, we added <strong>latency<\/strong> and <strong>packet loss<\/strong> in CML using link conditions. After running the test, we observed network degradation and saw how the ThousandEyes agent detected packet loss and increased latency. Once we removed the simulated link conditions, the network performance returned to normal, proving that our setup was functioning correctly.<\/p><p>The post highlighted how <strong>ThousandEyes<\/strong> on <strong>Catalyst routers<\/strong> provides real-time network monitoring, offering insights into network performance and resilience under different conditions.<\/p><p>To wrap up, it\u2019s important to keep in mind that deploying <strong>ThousandEyes<\/strong> on <strong>Catalyst routers<\/strong> requires specific hardware and software configurations. While we demonstrated the process using a <strong>Catalyst 8000v<\/strong> in a lab environment, <strong>only certain Catalyst models<\/strong> officially support application hosting, such as the <strong>Catalyst 8300<\/strong> and <strong>Catalyst 8500<\/strong> series.<\/p><p>Additionally, when planning a deployment, ensure your router has sufficient <strong>RAM<\/strong> and <strong>CPU resources<\/strong>. For example, running ThousandEyes typically requires at least <strong>4GB of RAM<\/strong> for smooth operation. You\u2019ll also need to check if your router supports the <strong>IOx platform<\/strong> and ensure you&#8217;re using a supported <strong>IOS-XE software version<\/strong>.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0c67284 elementor-widget elementor-widget-image\" data-id=\"0c67284\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/www.cisco.com\/c\/en\/us\/td\/docs\/routers\/cloud_edge\/c8300\/software_config\/cat8300swcfg-xe-17-book\/thousandeyes-application.html\" rel=\"noopener\">\n\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"338\" src=\"http:\/\/192.168.1.213:8088\/wp-content\/uploads\/2024\/10\/deploying_thousandeyes_on_catalyst8000v_010-1024x432.png\" class=\"attachment-large size-large wp-image-2532\" alt=\"\" srcset=\"http:\/\/192.168.1.213:8088\/wp-content\/uploads\/2024\/10\/deploying_thousandeyes_on_catalyst8000v_010-1024x432.png 1024w, http:\/\/192.168.1.213:8088\/wp-content\/uploads\/2024\/10\/deploying_thousandeyes_on_catalyst8000v_010-300x127.png 300w, http:\/\/192.168.1.213:8088\/wp-content\/uploads\/2024\/10\/deploying_thousandeyes_on_catalyst8000v_010-768x324.png 768w, http:\/\/192.168.1.213:8088\/wp-content\/uploads\/2024\/10\/deploying_thousandeyes_on_catalyst8000v_010.png 1410w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/>\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-72a35f4 elementor-widget elementor-widget-text-editor\" data-id=\"72a35f4\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Lastly, don&#8217;t forget about the <strong>software licenses<\/strong>.
