ICMP packets.

Enabling IPv4 local fragment reassembly

This feature improves IPv4 fragment reassembly efficiency on distributed devices as follows:
•
In standalone mode, this feature enables the receiving LPU to reassemble the fragments of an
IPv4 packet if all the fragments arrive at it. If this feature is disabled, all fragments are delivered
to the active MPU for reassembly. The feature applies only to fragments destined for the same
LPU.
•
In IRF mode, this feature enables the receiving subordinate to reassemble the fragments of an
IPv4 packet if all fragments arrive at it. If this feature is disabled, all fragments are delivered to
the master device for reassembly. The feature applies only to fragments destined for the same
subordinate.
To enable IPv4 local fragment reassembly:
Step
1. Enter system view.
2. Enable IPv4 local
fragment reassembly.

Remarks
N/A
By default, the device uses the IP
address of the sending interface as the
source IP address for outgoing ICMP
packets.
Remarks
N/A
By default, IPv4 local fragment
reassembly is disabled.
