Maximum Unit Settings

Description

The maximum unit settings are configured using two menu items:

zMaximum receive unit (MRU)—Defines the maximum number of bytes that can be received in a single packet.

zMaximum 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, AI232 will advertise the MRU configured by the user. If the peer negotiates its MRU with AI232, then the MTU on the AI232 side will be set to the peer’s MRU. If the peer does not negotiate its MRU, then the MTU on the AI232 side will be set to the value configured by the user.

Configuration in the AI198 Menu System

1.Do one of the following:

z For an asynchronous PPP link, access Menu 4.2.14.12-2.2. z For a ModMux link, access Menu 4.2.14.12.10.

2.For 05 Maximum Receive Unit, enter 5, and the byte value. The defaults are 1518 for network control protocol BCP and 1500 for network control protocol IPCP.

3.For 06 Maximum Transmit Unit, enter 6, and the byte value. The defaults are 1518 for network control protocol BCP and 1500 for network control protocol IPCP.

This example displays 05 Maximum Receive Unit set to 1000 and 06 Maximum Transmit Unit

set to 900.
