I've set up 2 s4148F's with a VLTi and there are several machines connected with LACP across both switches. So far that's working fine.
Now I'd like to add a non-LAG connection on both switches so 2 devices can talk with each other in their own vlan, like this:
device A <--> (untagged port vlan 100) switch B <-VLTi-> switch C (untagged port vlan 100) <---> device D
in this setup, A and D can not reach each other. I suspect this is because the VLTi can only carry port channel traffic and I'm not setting up a LAG here so I'm not configuring these ports to be in a port-channel.
I have a 100g connection between switch B and C, which is in use for the VLTi. It's not allowed to change the port configuration to trunk, because the VLTi usage won't allow it.
How can I get device A and B to talk with each other?
Is the VLT link configured to pass VLAN 100? Everything that I have been able to find does talk about it with port channels so that may be the case.
The interfaces that the VLT runs over can't be configured to allow vlan 100:
sw-06-of01(config)# vlt-domain 1 sw-06-of01(conf-vlt-1)# show configuration ! vlt-domain 1 discovery-interface ethernet1/1/25-1/1/26 peer-routing sw-06-of01(conf-vlt-1)# exit sw-06-of01(config)# interface ethernet 1/1/25 sw-06-of01(conf-if-eth1/1/25)# show configuration ! interface ethernet1/1/25 description "VLTi crosslink to sw-07.of01" no shutdown no switchport mtu 9216 flowcontrol receive off sw-06-of01(conf-if-eth1/1/25)# switchport trunk allowed vlan 100 % Error: vlan100, Interface being added (to VLAN) is not in switchport mode trunk!. sw-06-of01(conf-if-eth1/1/25)# switchport mode trunk % Error: Discovery Interface mode must not be in switchport mode!.
I am wondering what the best practice setup is for these kinds of situations to enable this normal type of traffic to flow through?
Can you private message me the service tag?
