pruning and trunk allowed

mattsthe2

So is vtp pruning and switch trunk allowed the same thing in essence??

I understand that vtp pruning is a little bit more intelligent versus hard coding the vlans allowed on the trunk, but doesnt it all amount to the same thing?

trunking = all vlans can travel on the link.

prunning (can only use prunning on a trunk link) = only vlans past this link will go across the trunk (saves bandwidth)

i think you missed my "allowed" keyword.

Sorry very tired just can't get this python script right, 7 hours now


You would hard code the Vlans as a simple form of traffic shaping, or let prunning do the job if no shaping reqiured. Can use both too.

Hope this more what you after?

i think so...so your answer is yes its basically the same.

Well yes in the sense thy could do the same thing but there is a BIG but:

With hard code you'd have to work out what Vlans are where and hard code these. Taking ages and wold prob mess up - Not very dynamic, as if the network changes you'd have to go in all your switches and change the hard code. Prunnning works this all out before you can blink.

In a production network you would have prunning turned on and maybe some shaping to stop certain Vlans ( voice vlans for example) going through certain switches on thier way to their dest.
