Object
column SNMPv2-SMICounter64
As packets travels, it is sometimes necessary to break a packet
into smaller fragments based upon the maximum transmission unit
(MTU) of each network. IP fragments might contain an attacker's
attempt to exploit the vulnerabilities in the packet reassembly
code of specific IP stack implementations. When the victim
receives these packets, the results can range from processing
the packets incorrectly to crashing the entire system.
When the block IP framentation flag is enabled, the device blocks
all IP packet fragments that it receives at interfaces bound to
that zone.
This attribute counts the number of block IP fragment packets.
