Kentrox AI296 User Manual

AI296 Version 9.8x User’s Guide

Link Configuration: General PPP Properties Configuration

Maximum Unit Settings

The maximum unit settings are configured using two menu items:

z

Maximum receive unit

 (MRU)—Defines the maximum number of bytes that can be 

received in a single packet.

z

Maximum transmit unit

 (MTU)—Defines the maximum number of bytes that can be 

transmitted in a single packet.



Note: During LCP negotiations on a PPP link, AI296 will advertise the MRU 

configured by the user. If the peer negotiates its MRU with AI296, then the 
MTU on the AI296 side will be set to the peer’s MRU. If the peer does not 
negotiate its MRU, then the MTU on the AI296 side will be set to the value 
configured by the user.
