Fragmentation and Reassembly
X330WAN supports fragmentation of IP packets according to RFC 791, and
reassembly of IP packets destined only to its interfaces.
Reassembly is associated with the following user-configurable parameters:
•
Fragment Size - The maximum number of concurrently reassembled packets:
Range: 0-200; Default=100.
• Fragment Timeout - The maximum time, in seconds, to wait for a packet to be
reassembled:
Range: 5-120; Default=10.
• Fragment Chain - The maximum number of fragments allowed per packet:
Range: 2-2048; Default=64.
To configure reassembly, use the following commands:
Configuring X330WAN to Connect Branch Offices to Headquarters
Many businesses have a centralized location for their headquarters and small
branch offices. It is important that communication between the headquarters and
the branches flows quickly. The following figure shows a typical configuration of
the network connecting the headquarters with branch offices.
Note: The following example uses sample IP addresses for illustration only.
• fragment size Sets the maximum number of fragmented IP packets
destined to the router that can be reassembled
concurrently.
• fragment chain Sets the maximum number of fragments that can
comprise a single IP packet destined to the router.
• fragment timeout Sets the maximum number of seconds to reassemble a
fragmented IP packet destined to the router.
• clear fragment Sets the reassembly parameters to their defaults, as well
as clears the reassembly database.
• show fragment Displays information regarding fragmented IP packets
destined to the router (the status of the reassembly
operation).
