trust boundaries

Hi all

can anyone help me out with trust boundaries, if I trust the frames coming in from my phone on my switchport, has this moved the trust boundary then to the phone?

I would of thought the switch is classed as the trust boundary ?

trust boundaries

Hi Carl,

no the trust boundary stays on you switch, which is the network boundary where you take the decision whether trust QoS marking received from 'external' devices or reset them.

I understand that your doubt might arise from the fact that you also own/administer the ip phones, but the trust boundary is a concept typical of switched/routed networks and apply to devices which switch/route traffic only, not to the ones which generate such traffic (phones, pcs, servers or all other hosts in general).
