We have a Stratix 5400-series switch with Siemens relays connected to three switch ports. The relays need to be able to communicate with each other via GOOSE, the ports are all on the same VLAN, and the GOOSE traffic is all constrained to just that Stratix switch. From reading various documents/tech notes, I know that GOOSE requires a trunk port rather than an access port to the end device, has some requirements around needing to use "VLAN 0" and QOS, but I could not find an example "base" port configuration for a GOOSE end device. The below configuration snippet is what we've been using:
interface FastEthernet1/1
switchport trunk native vlan abc
switchport mode trunk
srr-queue bandwidth share 1 19 40 40
priority-queue out
mls qos trust cos
macro description switch-automation
alarm profile ab-alarm
spanning-tree link-type point-to-point
service-policy input CIP-PTP-Traffic
Where abc is the VLAN where the GOOSE devices reside. Designating abc as the native VLAN for the trunk allows us to ping the Siemens devices. However, we have no way to test if the Siemens devices are actually exchanging GOOSE communications and "working"; that is another vendor's responsibility. But we'd like to know that the correct configuration is in place before that testing begins. Can anyone suggest such a "base" port configuration, and/or a way to test that these devices are able to speak GOOSE to each other?
