Enabling Ipv4 Local Fragment Reassembly; Displaying And Maintaining Ip Performance Optimization - HP FlexNetwork MSR2003 Configuration Manual

Step
2. Specify the source
address for outgoing
ICMP packets.

Enabling IPv4 local fragment reassembly

Perform this task to enable the local reassembly feature for IPv4 fragments that are destined for the
local device. This feature enables the receiving LPU to reassemble the IPv4 fragments instead of
delivering them to the active MPU for reassembly. It improves the fragment reassembly
performance.
To enable IPv4 local fragment reassembly:
Step
1. Enter system view.
2. Enable IPv4 local
fragment reassembly.
Displaying and maintaining IP performance

Remarks
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.
This feature applies only to fragments
received by the same LPU.
