literature for your routing devices to see the optimum settings for your
network.

IP Reassembly tab.

To disable IP reassembly, clear the Enable IP reassembly check box. To adjust
reassembly parameters, type the preferred parameters in each field.
Guidelines:
■ If the Maximum Packets Allowed, Maximum Packet Size, Maximum Fragments
per Packet, or Maximum Fragment Size limits are set too low or too high,
memory will be depleted too quickly and performance will suffer.
■ If the Maximum time to receive all fragments limit is set too low, standard
network latency may cause the transfer to be abandoned too soon.
Conversely, if the limit is set too high, the device will wait too long before
reporting missing packets, which will degrade performance.
