If a Gateway is configured as a Partner Gateway with static routing, and the ICMP responder is configured to track the reachability of those routes, a debug.py command is provided to indicate the UP or DOWN states, as follows:
vcadmin@vcg1-example:~$ sudo /opt/vc/bin/debug.py --icmp_monitor
{
"icmpProbe": {
"cTag": 0,
"destinationIp": "0.0.0.0",
"enabled": false,
"frequencySeconds": 0,
"probeFail": 0,
"probeType": "NONE",
"probesSent": 0,
"respRcvd": 0,
"sTag": 0,
"state": "DOWN",
"stateDown": 0,
"stateUp": 0,
"threshold": 0
},
"icmpResponder": {
"enabled": false,
"ipAddress": "0.0.0.0",
"mode": "CONDITIONAL",
"reqRcvd": 0,
"respSent": 0,
"state": "DOWN"
}
}
vcadmin@vcg1-example:~$
When the ICMP responder is enabled, the DOWN state means that there are no Edges connected to the Gateway.
