I have a Dell Sonicwall NSA 4600 running the latest firmware with an Interface that's configured to have a secondary redundant port. This interface also has a VLAN sub interface assigned to it.
On the switch, a Dell S4048-ON, there is a Port Channel configured with the two physical interfaces connected to the Sonicwall. This Port Channel is a hybrid switchport with one untagged and one tagged VLAN.
I'm having issues with traffic when I connect a client to the switch on either the tagged or untagged VLAN uplink to the Firewall. I can't ping the Firewall's Interfaces when setting the clients IP statically in either VLAN.
If I do this same configuration but on a single physical interface, and thus no Port Channel, it works as I'd expect.
Is there something I'm missing here when trying to introduce a Port Channel?
Let me know if there's anymore info I can provide that might be of use.
