you mean this? https://kb.netapp.com/on-prem/ontap/da/NAS/NAS-KBs/How_to_prove_that_CFM_frames_are_being_dropped_on_the_network
I usually see one of three scenarios
- The vlan(s) is/are not defined on the connection (trunk or port channel) to the Netapp
- The vlan(s) is/are not defined on the switch
- Both of the above
there are no VLANs defined, neither on Netapp nor on the switch
Are you using everything in access mode then? Everything would be in vlan 1?
If you are specifying an access vlan for the ports and the vlan isn’t defined on the switch then there might be an issue
ok a bit more clarifying information:
access mode: yes. untagged: yes. Port configured for VLAN16
there is an access vlan for the ports, and the vlan is configured. Do you mean a CFM specific config for the vlan?
Traffic is passing fine, so the general VLAN config is working, just not CFM
Maybe IOS blocks all CFM in all but the native VLAN or something? Not sure. In Nexus switches it just works
Ok: is vlan 16 defined on the switch?
Show vlan -> make sure it’s defined. If it’s not
Config t
Vlan 16
Name whatever
End
Wr mem
would it even forward anything if the VLAN was not defined?
It may. I know I’ve seen customers simply make a bunch of access ports a certain vlan and they ask seem to talk. Maybe the cfm depends on the vlan being defined? Don’t know. It was just a question to make sure it was actually there
