What u say about inter-vlan communication is it possible ..... if
yes plz tell how ????
A VLAN is a *virtual LAN*, i.e., distinct VLANs appear to be physically
separate Local Area Networks. As with all separate networks,
communication among them can be effected by using a router.
And is inter- port based vlan communication is possible in l 2 switch
or for this the switch controller register support is required
Please read my original response. Communications among VLANs (indeed,
among *any* LANs) can be accomplished using a router. I am sorry if you
do not understand this, or if this is not the answer you want.
I have no idea what a "switch controller register" *is*, much less
whether it may be required for inter-port based VLAN communication.

Hello Sir
I ve a query related to inter-vlan(port based) communication
so first please read my query which in my share web file
named as
stp and vlan case.txt
the link for my share web file is --
http://vikrantpandey.diinoweb.com/files/
please read it and then please reply.
I read your file, and my answer is unchanged. You seem to believe that,
because there are multiple ports physically connected to a single
switch, that the switch *MUST* provide the mechanism for communicating
among all of those ports. However, if you configure some of the switch
ports to be in disjoint VLANs (as you have), then it is possible--
indeed, likely--that the switch will NOT provide such communication. By
configuring separate VLANs as you have shown, you are, in essence,
telling the switch NOT to allow communication directly among those VLANs.
As I have said many times now, communications among VLANs can be
accomplished using a router. In the diagram you have provided, you show
no router, so there will be no communications among the separate VLANs.
If you want communications among all of the ports, then don't configure
them into separate VLANs.
