Configuring Lfi; Displaying And Maintaining Ppp And Mp - HPE FlexNetwork MSR series Configuration Manual

Configuring LFI

Real-time packets, such as Telnet and VoIP packets, might be blocked or delayed on a low-speed
interface.
To reduce delays and jitters on low-speed links, LFI fragments large packets into small fragments.
The fragments are reassembled at the destination.
Figure 2 illustrates the LFI process. When large packets and small voice packets arrive at a
WFQ-enabled interface, LFI performs the following operations:
•
Fragments the large packets into small fragments.
•
Adds the fragments to the queues along with the voice packets.

To configure LFI:
Step
1. Enter system view.
2. Enter
interface, or dialer interface view.
3. Enable LFI.
4. Set the maximum LFI fragment
transmission
maximum LFI fragment size (in
bytes).

By default, LFI is disabled.
Disabling LFI also removes the
user-configured settings of the
maximum LFI fragment delay and
size.
By default, the maximum LFI
lfi
fragment transmission delay is 10
ms, and the maximum
fragment size is the expected
lfi
bandwidth of the interface times
the maximum delay divided by 8.
