Hi,
I`m configuring 802.1q trunking between CAT 6500 and passport 8600, in CAT 6500 I configure the port as trunk dot1q mode ON. In Passport 8600 I configure the port as TAG port.
I cretate the same vlans in both switch, but the interface vlans are create in CAT Switch. all hosts in Passport Switch that belongs to vlan 1 can ping his default gateaway (Interface Vlan) but hosts that belong to other vlan no.
