To modify the history size for a circuit, complete the following tasks:

Preventing Data Loss for PPP and Frame Relay

Buffer size

is the amount of memory allocated to store the transmission history.

You must configure this parameter to protect against data loss if you run PPP or

frame relay. You can use a buffer size of None, Normal, Large, or Very Large. The

default value is Normal. Configure buffer size based on the following conditions:

• Length of time it takes for data to travel over the link

A Normal buffer size is usually large enough for a coast-to-coast connection

within the United States. You may need a Large or Very Large buffer if your

link is over a satellite connection.

• Number of dropped packets

For a link with a high number of dropped packets, increase the buffer size. For

a link with a very low number of dropped packets, decrease the buffer size,

even to None, to conserve memory.
