Two 2950 switches, one in vtp server mode & one in vtp client mode & a trunk between the two. two vlans (vlan1 & vlan2) created on the vtp server switch. Ports 1 & 2 are assigned to vlan1 & ports 3 & 4 are assigned to vlan 2 on the vtp server switch. I now log on to the vtp client & enter the "show vlan" command & the two vlans & port assignments are displayed.
I now assign ports 5 & 6 of the vtp client switch to vlan1 & enter "show vlan" & the new port assignments are displayed. But! If I disconnect from the vtp client switch & then reconnect to the vtp client & enter "show vlan" again, the port assignments that I previously made on the vtp client are no longer shown, only the original assignments made on the vtp server are shown. Why is this?
As mahmood has already mentioned that by default all the ports are in vlan1, try assign the ports 5&6 to other vlan 1 on you client switch and if you disconnect the switch all the ports will show in their respective vlans. VTP is only used to propogate the vlans from the VTP server to client switches it doesnot propogate or related to the local port assignment of the ports in the vlans.
