210 CHAPTER 16: CONFIGURING LAPB AND X.25
Tabl e 250 Specify/Cancel packet pre-acknowledgement
By default, the number of pre-acknowledged packets is 0.4Configure X.25 user facilityX.25 protocol defines various user facility options. The user can choose and configure the facilities. These configurations can be modified in two ways:Configuration based on X.25 interface (use "x25 call-facility....." command); configuration based on address mapping (use "x25 map......" command).The configuration based on X.25 interface will be effective in every call originated from this X.25 interface, while the configuration based on address mapping will be effective only in the calls originated from this address mapping.In the interface view, perform the following task.Tabl e 251 Configure X.25 user facility
