Chapter 16 Fragmenting and Interleaving Real-Time and Nonreal-Time Packets

MLP Over Serial-Based LFI

MLP over serial-based LFI uses the fragmentation and interleaving capability of MLP to integrate
real-time packets (such as voice packets) and nonreal-time packets (such as data transfers) on the same
link while reducing real-time packet latency.
MLP allows you to bundle T1 interfaces into logical groups. As indicated in
configure a MLP bundle with up to 10 T1 links. Using MLP, you can create a degree of redundancy by
configuring a MLP bundle that is made up of T1 links from more than one line card. If one line card
stops operating, the part of the bundle on other line cards continues to operate.

Feature History for MLP Over Serial-Based LFI

Cisco IOS Release
Release 12.0(23)SX
Release 12.2(27)SBB This feature was introduced on the PRE2.
Release 12.2(31)SB2

Performance and Scalability for MLP Over Serial-Based LFI

To enhance performance and scalability for MLP over serial-based LFI, configure the hold-queue
command in interface configuration mode for all physical interfaces, except when configuring the ATM
OC-12 line card. The OC-12 does not require the hold-queue command. For example:
Router(config-if)# hold-queue 4096 in

shows a MLP bundle that consists of T1 interfaces from three T3 interfaces.

You can combine up to ten T1s to create a Multilink bundle.
The bundle can include T1 channels assigned to different T3s.

Description
The MLP over serial-based LFI feature was introduced on
the PRE1.
This feature was introduced on the PRE3 and the valid
multilink interface values changed from 1 to 9999
(Release 12.2(28)SB and later) to from 1 to 9999 and
65,536 to 2,147,483,647.
