IDBs provide a central location in memory for storing information about network interface cards for use by the interface driver code. They are able to represent all knds of interfaces including subinterfaces.The IDB data stuctures also use alot of memory so Cisco has limited them to 300 per router. Each physical whether it is configured or not or if it is up or shut uses one IDB.It works the same for the subinterfaces, each subinterfaces gets one IDB. e.g one interface has 5 subinterfaces so there are 6 IDBs allocated. Subinterfaces use IDBs but FR PVCs don't.If a FR has 10 PVCs and does not use any subinterfaces it uses a single IDB. Another example:1 interface with 2 subinterfaces each having 3 PVCs only use 3 IDBs. Hope This helps >From: "John W. Redmond" <[EMAIL PROTECTED]> >Reply-To: "John W.
