Node Ping Gateway
Tool
Use the node_script tool to run this skill:
node_script: node="<node>", skill="node-ping-gateway", script="ping-node-gateway.sh", args="<args>"Parameters
| Parameter | Required | Description |
|---|---|---|
--interface IFACE |
yes | Network interface to find gateway for |
--source-ip |
no | flag, auto-detect IP from interface, use as ping source (-I <ip>) |
--source-dev |
no | flag, use interface name as ping source (-I <iface>) |
--count N |
no | Number of ping packets (default: 3) |
--source-ip and --source-dev are mutually exclusive flags (no value needed).
Examples
node_script: node="nodepool-061", skill="node-ping-gateway", script="ping-node-gateway.sh", args="--interface bond0"node_script: node="nodepool-061", skill="node-ping-gateway", script="ping-node-gateway.sh", args="--interface eth0 --source-ip"node_script: node="nodepool-061", skill="node-ping-gateway", script="ping-node-gateway.sh", args="--interface eth0 --source-dev"Switchdev Note
If the target interface is a PF in switchdev mode (e.g. eth0/eth1), ping will always fail —
this is expected behavior, not a network problem. The PF acts as an embedded switch and cannot
send or receive regular traffic.
What to do instead: run node-list-roce-pods on the node to find a RoCE pod,
then use pod-ping-gateway on that pod. This tests the actual VF data path.
See roce-diag-sriov-switchdev for full background.
See pod-ping-gateway for the pod version.
