Having two 3560 switches trunked with 802.1Q, I know Vlan 1 will be used internally by the switches for vtp, pagp, stp traffic. You can't stop this happening. right?
By creating another native vlan say 50 on the trunk, will vlan 50 be use to create stp, vtp information instead of vlan 1. Will STP bpdu sent for vlan 1 across the trunk by dafult?
on a cat 3560 says Spanning tree instance(s) for vlan 1 does not exist
