The Trellix DXL Fabric page (in ePolicy Orchestrator) is the central place to view, manage, and troubleshoot the DXL broker infrastructure within your environment. Here’s a quick overview of what you’ll find and do on this page:
Navigation in ePO Console:
Menu → DXL Broker Management → DXL Fabric Page
DXL Fabric Page Overview:
| Section | Description |
| Fabric Topology Map | A visual representation of all DXL brokers in your environment, including their connections, status (green = connected, red = disconnected), and peer relationships. |
| Broker List / Table View | Lists all brokers with details such as hostname, IP, status, broker group, topology version, and last connection time. |
| Topology Version | Shows the version of the current topology distributed to endpoints. If endpoints have an outdated version, communication issues can occur. |
| Broker Groups | Logical grouping of brokers for scalability and routing purposes. Each group typically represents a site or region. |
| Actions Toolbar | Allows actions like push topology, export topology, or view broker properties. |
Common Admin Actions on DXL Fabric Page:
- Verify Broker Connectivity
Check if all brokers are connected (green). If a broker shows red, verify network, service status, and certificates. - Push Topology to Agents
If brokers have been added/removed or topology has changed, click “Push Topology” to update all DXL clients. - Edit Broker Properties
Update broker name, IP, group, or trust settings if needed. - Check Peer Relationships
Ensure brokers are correctly peered for redundancy and performance. Misconfigured peers can lead to lookup failures.
Troubleshooting Tips:
If clients are failing DXL communication:
- Check the broker they’re assigned to and confirm it’s green in the Fabric page
- Look out for any error message such as Outdated topology or certificate issues, which often show up in the Fabric page
- If all mappings look correct but DXL communication is still failing, please contact CSP Global Support so that we can further troubleshoot this
