Hi,

You should also keep in mind, for SNMP/syslog interaction, that SNMP/UDP
messages should not be fragmented if possible, to handle the case when
some packets are dropped.

To claim compliance with the standard, implementors must support
messages up to and including 484 octets. They are encouraged to support
larger sizes up to 1472 octets. The 1472 number is the largest SNMP
message that will fit into an Ethernet packet without forcing
fragmentation, if I remember correctly.
