<DL>
<DD>Set the size of the buffer used to receive response packets. RFC 1157 stipulates that an SNMP
   implementation must be able to receive packets of at least 484 bytes, so if you try to set the
   size to a value less than this, the receive buffer size will be set to 484 bytes. In addition,
   the maximum size of a UDP packet payload is 65535 bytes, so setting the buffer to a larger size
   will just waste memory. The default value is 512 bytes. The value may need to be increased if
   get-requests are issued for multiple OIDs.
