Displaying And Debugging Ppp/Mp/Ppp Link Efficiency Mechanisms - 3Com 3C13636 Configuration Manual

3Com Router 3000 Ethernet Family
Configuration Guide
I. Enabling LFI
Perform the following configurations in virtual template interface view or MP-group
interface view.
Table 1-33 Enable LFI
Enable LFI on Virtual Template interface
Disable LFI on Virtual Template interface
LFI is not enabled by default.
II. Configuring maximum time delay of LFI fragments
The following command sets the maximum time delay for transmitting an LFI
fragment.
Perform the following configurations in virtual template interface view or mp-group
interface view.
Table 1-34 Configure maximum time delay of LFI fragment
Configure maximum time delay of LFI
fragment
Restore the default maximum time delay
of LFI fragment
The default fragment delay is 10 milliseconds after LFI is enabled.
The fragment size is calculated considering the specified forwarding delay as follows:
Fragment size = Virtual bandwidth of virtual interface x LFI delay
The minimum fragment size you can configure on the router is 40 bytes. If a smaller
fragment size is calculated for a packet, the router chops it into 40-byte fragments.
For assigning bandwidth to a virtual interface, refer to the qos max-bandwidth
command.
