So, every time a notification sender sends a trap or notification it would set-up a TCP connection to each of the notification receivers in its list and keep that connection up indefinitely? Would it reestablish ithose connections when they fail? How long would it keep a connections up if it never receives a command request on that particular connection? Please remember that not all notification receivers _are_ command requestors, and not all command requestors are notification receivers. I do think that if you built a mechanism for a command responder to open a connection to a command requestor, the MIB for configuring the new mechanism might resemble the MIB that is used to determine notifications should be sent, but I don't think that it will be identical and I do not think that the current MIB should be overloaded in this way. BTW, nothing about your note explains to me why you think that this mechanism should be defined in a Security area WG that is working on a completely separable problem. If you really think that defining call home for SNMP is something that the IETF should do, I would encourage you to get together with Eliot and request a BOF in the OPS area.
