Fellow Frame Relay Mibbers and Mibbettes - I have a comment concerning draft version 5 of the Frame Relay DTE MIB concerning the multicast object for a virtual circuit. It is currently defined in the draft as: frCircuitMulticast OBJECT-TYPE SYNTAX INTEGER { unicast (1), multicast (2) } MAX-ACCESS read-only STATUS current DESCRIPTION "This indicates whether this VC is used as a multicast VC or a single destination" ::= { frCircuitEntry 15 } The first problem (major) is that this is a read-only object. It should be read-write. This object doesn't do much good if you can't manipulate it via an SNMP manager. The second comment is that this object only has a simple yes/no function concerning multicast. The Frame Relay Forum Multicast Service and Protocol Description Implementation Agreement (FRF.7 October 21, 1994), defines a Multicast service as being One-Way, Two-Way or N-Way. I therefore propose the object to be changed as follows: frCircuitMulticast OBJECT-TYPE SYNTAX INTEGER { unicast (1), oneWay (2), twoWay (3), nWay (4) } MAX-ACCESS read-write STATUS current DESCRIPTION "This indicates whether this VC is used as a unicast VC (i.e. not multicast) or the type of multicast service subscribed to" REFERENCE "Frame Relay PVC Multicast Service and Protocol Description Implementation: FRF.7 Frame Relay Forum Technical Committe October 21, 1994" DEFVAL {1} -- the default value of frCircuitMulticast is -- "unicast" (not a multicast VC). ::= { frCircuitEntry 15 } Also since multicast is optional we should allow an implementation to only allow a write of unicast(1) as a value and to allow other values to be optional.
