RAQMON Trap PDU size and report transmission time

Hi,

Does anyone know how many RAQMON-RDS-MIB varbinds can fit in 
an unfragmented SNMP Trap PDU?  (IPv4 as well as IPv6).

It seems to me that all of the Basic report parameters should be 
reported at least once per session, otherwise they shouldn't be 
in the common parameter list.  If the Basic report needs to be 
fragmented into multiple Trap PDUs, then RDS complexity is 
increased, and the likelihood goes up that a maximum transmission 
rate of 1 Trap PDU every 2 minutes becomes a bottleneck on the RDS.
