Node Show Gateway

Tool

Use the node_script tool to run this skill:

node_script: node="<node>", skill="node-show-gateway", script="show-node-gateway.sh", args="<args>"

Parameters

Parameter	Required	Description
--interface IFACE	no	Network interface name. If omitted, shows all.

Examples

node_script: node="nodepool-061", skill="node-show-gateway", script="show-node-gateway.sh", args="--interface eth0"

node_script: node="nodepool-061", skill="node-show-gateway", script="show-node-gateway.sh"

Output

The output table includes a TYPE column identifying each interface type:

TYPE	Meaning
RoCE	Ethernet interface with an RDMA device attached
Ethernet	Regular Ethernet interface
IB	InfiniBand interface

Detection logic: /sys/class/net/<dev>/type = 32 → IB; type=1 and rdma link contains netdev <dev> → RoCE; otherwise → Ethernet.

Switchdev Note

If the target interface is a PF in switchdev mode, the displayed gateway routes are not meaningful —
the PF acts as an embedded switch and cannot send or receive traffic as an endpoint.

What to do instead: run node-list-roce-pods on the node to find a RoCE pod,
then use pod-show-gateway on that pod. This tests the actual VF data path.
See roce-diag-sriov-switchdev for full background.

See pod-show-gateway for the pod version.
