Restrictions for MLP to Be in the Hardware Accelerated Mode

If the restrictions in this section are met, the Multilink PPP (MLP) bundle operates in hardware mode by
default.

•

The maximum supported member link bandwidth is T1. If a clear channel interface is made part of
a Multilink bundle, the bundle will operate in software mode.

•

All links in the bundle must be of equal bandwidth. Adding a link of unequal bandwidth causes the
Multilink bundle to go into software mode.

•

All links must be from the same port adapter. Adding any additional link from another port adapter
causes the bundle to switch to software mode.

•

A maximum of 12 links per bundle is supported. Adding any additional links to the bundle causes
the Multilink bundle to go into software mode.

•

Configuring

ppp multilink multiclass

MLP causes the Multilink bundle to go into software mode.

•

Fragment sizes supported in the hardware mode are 128, 256, and 512 bytes. If different
fragmentation sizes are configured, and if the bundle is in hardware mode, fragment size is adjusted
to the nearest of the supported fragment sizes, and the hardware is programmed accordingly.

•

The bundle will operate in software mode if MLPPP is configured using Virtual-Templates as described
in the following link.

http://cco/en/US/tech/tk713/tk507/technologies_configuration_example09186a00800a3e98.shtml

Use the

show ppp multilink

command to display fragmentation size if the fragment size has been

configured.

If interleaving is enabled, and no fragmentation has been configured, the fragment size is selected
based on the link size displayed in
