The ACEB box is near my equipment.
My PC and the ACEB box are both connected to a CISCO Catalyst 4510R.
We have encountered problem with the ntp card of the clock several

When too many clients are connected the clock used to have problems.
May be this problem of latency and asymmetry comes from the ntp card.
