CCMs not passing

Wed Sep 18, 2019 12:45 pm

On our network we use end-to-end Circuit Connectivity Messages (CCMs) to insure that all switch VLAN configurations are correct. When we installed our first switches we did not have any issues and the CCMs were passed through the Netonix switches (WS-8-150-ac) OK. However since the ERP feature has been added CCMs are no longer passed through the switch. We have had multiple emails with technical support with no success.

CCMs use multicast to establish the end-to-end monitoring. When we look at the port detail statistics we see the muticast packets being received on the port but do not see them being transmitted on any other port.

We even changed the CCM ethernet type to 8100 with no luck.

Has anyone else had this problem and were able to fix it?
