Hi GS,

I have a question: when an IP phone connects to a switch, by default,
the switch will automatically establish a trunk with the IPphone.
Good. I didn' check that yet, but this makes me conclude tha DTP is
working in the IP phone. Does it also supports VTP ?

To be clearer, If I configure vtp prunning in my switch domain and
later on I plug a IP phone in an interface, is that new trunked
interface prunned by default or will it be receiving
floods/broadcast/multicast unnecessarily ( and so to solve it I make
tune the vlan allowed list )?

Thanks !

Daniel
