OpenNMS Horizoon demo environment with Docker and Docker Compose.
Initialize the environment.
git clone https://github.com/opennms-forge/opennms-demo.git
cd opennms-demo
docker-compose up -d
HINT: By default OpenNMS Horizon uses the floating tag latest with the current stable release from DockerHub.
To feed the demo environment with data you can use the demo-data.sh script which does following things:
- Creates a foreign-source without detectors
- Creates a requisition with all nodes from the demo environment
- Uploades a GraphML topology which represents the network topology named OpenNMS Demo
Usage:
cd setup
./demo-data.sh
Forwarding LLDPDU is not enabled by default on Linux bridges.
To enable LLDPDU forwarding it is required to change the group_fwd_mask for a given bridge.
Using docker-compose up -d will create two additional bridges from this repository.
One bridge simulating a local area network and second bridge for a isolated network in a remote office.
To enable LLDPDU forwarding it is required to identify the bridge on the docker host system with:
docker network ls
a0713f06e511 lldp_branch bridge local
2bde8ffcb81b lldp_default bridge local
bb562d6d9e30 lldp_local bridge local
The NETWORK ID is part of the bridge name on the host system. To enable LLDPDU forwarding for the local network a bridge is created.
brctl show | grep bb562d6d9e30
br-bb562d6d9e30 8000.0242deaee63c no veth067f1fa
The filter can be set with
echo 16384 > /sys/class/net/br-bb562d6d9e30/bridge/group_fwd_mask
LLDPDU forwarding is now enabled and works immediately.
