Debug Helper Script for Quantum - Configure export TEST_CONFIG_FILE=/etc/quantum/dhcp_agent.ini or export TEST_CONFIG_FILE=/etc/quantum/l3_agent.ini you can also specify config file by --config-file option - Usage quantum-debug commands probe-create Create probe port - create port and interface, then plug it in. This commands returns a port id of a probe port. A probe port is a port which is used to test. The port id is probe id. We can have multiple probe probes in a network, in order to check connectivity between ports. quantum-debug probe-exec probe_id_1 'nc -l 192.168.100.3 22' quantum-debug probe-exec probe_id_2 'nc -vz 192.168.100.4 22' probe-delete Delete probe - delete port then uplug probe-exec 'command' Exec commands on the namespace of the probe `probe-exec ` 'interactive command' Exec interactive command (eg, ssh) probe-list List probes probe-clear Clear All probes ping-all --id --timeout 1 (optional) ping-all is all-in-one command to ping all fixed ip's in all network or a specified network. In the command probe is automatically created if needed. quantum-debug extends the shell of quantumclient, so you can use all the commands of quantum
