Pc1 and pc2 are in the same vlan 10 so don't need default-gateway, and I
disable firewall on both of them!

Putting aside any problems with the network, have you got the default
gateways on the pc setup properly? And what about the windows firewall
on XP?

Link connected between SW1-SW2 and SW2-SW3 is trunking dot1Q!
Nothing wrong with VTP, because SW3 can learn vtp message from SW1!
The problem is PC1 can not ping PC2 if i don't create VLAN10 on SW2!
if I create VLAN10 on SW2, then PC1 can ping PC2
thanks!

HaDucBinh,
For IP connectivity from SW1 to SW3, make sure your connection from SW1 to SW2 and SW2 to SW3 is a trunk ( carrying VLAN 10 & any other VLANs you want).
The purpose of SW2 mode of transparency is to just forward the VTP messages on to SW3. SW2 will never act or perform any action based on the VTP messages (i.e. - you must logon to SW2 to perform any changes). SW3 being a client will act on the messages received.

Hi GS!
I have a funny thing with VTP:
This is my topology:
PC1---SW1--------------SW2---------------SW3---PC2
(VTP server) (VTP Trans) (VTP Client)
This is my configuration on SW1,SW2,SW3: (all cat 2950)
SW1(config)# vtp mode server
SW1(config)# vtp domain CISCO
SW1(config)# vlan 1,2,3,4,5,6,7,8,9,10
SW1(config)# int f0/24
SW1(config-if)# sw mo ac
SW1(config-if)# sw ac vlan 10
SW2(config)# vtp mode transparent
SW2(config)# vtp domain CISCO
SW3(config)# vtp mode client
SW3(config)# vtp domain CISCO
SW1(config)# int f0/24
SW1(config-if)# sw mo ac
SW1(config-if)# sw ac vlan 10
PC1 connected to SW1 f0/24
PC2 connected to SW3 f0/24
This is result:
- SW3 have all VLAN learned from SW1, VLAN 1 to 10
- SW2 have only VLAN 1 (default vlan)
- Then pc1 CAN NOT ping pc2
- I use command: #show mac-address-table on SW3 -> no MAC entry of pc1 and pc2
But if we create vlan 10 on SW2:
SW2(config)# vlan 10
Then pc1 CAN ping pc2 and #show mac-address-table on SW3 -> we can see MAC entry of pc1 and pc2
So is this a bug of IOS?
I try on cat 3550 with ipservice 12.2(25)SEE2 -> still se this error!
If this is not error of IOS, so what's purpose of TRANSPARENT switch (SW3)??
Thanks!
