Suppose we have 4 switches runing in VTP mode. So when i create a VLAN in Server Switch this VLAN info reflect in all other switch. So question is - A) Suppose i m practicing this scenario in BOSON software, When a create a VLAN in server switch n ADD ports of switch to that VLAN, the same number of ports of client switch also belongs to dat VLAN.

Another Switch B (Client mode), its also showing that port number 1,2 & 3 belong the same VLAN. How cud it possible... As we know, VTP share only VLAN configuration information. Cud anyone explain it please....!!!! B)Same thing, when i m practicing in PACKET TRACER 5.0, its only showing that VLAN configuration information is shared. No port information is shared at all.
