Description

We are implementing “EVPN-VXLAN Lightweight Leaf to Server Loop Detection” as described in “https://www.juniper.net/documentation/us/en/software/junos/evpn-vxlan/topics/concept/evpn-vxlan-lightweight-leaf-server-loop-detection.html” and we are getting the following error when checking for the loop-detect status for an interface: “error: the ethernet-connectivity-fault-management subsystem is not running”

 

The switch is:

 

QFX5100-48T-6Q

Solution

QFX5100 devices don't support Enhanced loop detection protocol,

https://apps.juniper.net/feature-explorer/feature-info.html?fKey=9696&fn=Loop+detection+for+EVPN-VXLAN+fabrics

 

In fact, these devices don't support OAM feature,

https://apps.juniper.net/feature-explorer/parent-feature-info.html?pFKey=1139&pFName=Ethernet+OAM+connectivity+fault+management+%28CFM%29

 

Loop detection feature runs over oam, therefore none of the features is supported for the platform
