Syntax

virtual-defragmentation {maximum-defragmentation-per-host <1-16384>|
maximum-fragments-per-datagram <2-8129>|minimum-first-fragment-length <8-1500>|timeout <1-60>}

Parameters

virtual-defragmentation {maximum-defragmentation-per-host <1-16384>|
maximum-fragments-per-datagram <2-8129>|minimum-first-fragment-length <8-1500>|timeout <1-60>}


maximum- defragmentation-per-host <1-16384>	Optional. Configures the maximum number of active de-fragmentations allowed per host before it is dropped (applicable to IPv4 and IPV6 packets) <1-16384> – Sets a value from 1 - 16384. The default is 8.
maximum-fragments- per-datagram <2-8129>	Optional. Configures the maximum number of fragments allowed in a datagram before it is dropped (applicable to IPv4 and IPV6 packets) <2-8129> – Sets a value from 2 - 8129. The default is 140.
minimum-first- fragment- length <8-1500>	Optional. Defines the minimum length required for the first fragment (applicable to IPv4 and IPV6 packets) <8-1500> – Sets a value from 8 - 1500 bytes. The default is 8 bytes.
timeout <1-60>	Optional. Configures a virtual de-fragmentation timeout, in seconds, applicable to both IPv4 and IPv6 packets <1-60> – Specify a value from 1 - 60 seconds. The default is 1 second.
