How to tunnel all traffic from one port to another except management VLAN
I'm trying to configure an N2048 with what is probably an unusual use case and am having trouble getting exactly what I need. What I'd like to do is take all traffic (tagged or untagged) received at port A and send it out port X, except for management traffic, which is configured for VLAN 100, which should go to port Y.
I've come up with a few configurations that have almost worked, but not quite.
I started out trying to use "switchport trunk native." This mostly works. But I found that frames tagged with a CVLAN are not received at port X.
I then tried "switchport mode dot1q-tunnel." This resolves the CVLAN limitation and correctly forwards all traffic to port X, but I can't figure out a way to get the management traffic to port Y.
I went back to experimenting with trunk mode and figured out that I can get the CVLAN traffic to pass if I change the dot1q ethertype to something nonstandard, but then that once again breaks the VLAN100 management traffic. Possibly because that traffic is now also using the configured nonstandard ethertype?
Is there any way to have one configuration that doesn't have either of these limitations?
