Hi there, i have 2 switches, a 2960 and a 3750 connected with trunk links. In the 3750 switch i have the native vlan tagging on. On 2960 i was told by cisco personnel that i doesn't support native vlan tagging. Though, i have placed a sniffer on the 3750 and i get tagged and untagged frames. Isn't it a little strange? Shouldn't the 3750 reject all the untagged frames?
