i am doing cascade from Access switch, one of the port which vlan 288 connect to another cisco switch (act like hub), i got the error from the both switch . Native Vlan mismatch.
Switch A (Access Switch).
switchport access vlan 288
switchport mode access
switchport voice vlan 274
Switch B (cascade)
switchport trunk encapsulation dot1q
switchport trunk native vlan 288
so, if i put both site encapsulation dot1q and native vlan .. i wont get the native vlan mismatch. but, i am unable to get the ip address.
