3Com Router Command Reference Guide — V1.00level working status “1” during the idle time. To improve the compatibility withequipment, you need to change the idle time encoding mode of our routers.You may need to configure the idle-mark command when connecting AS/400, that is,to change the idle time encoding mode in order to accelerate the polling rate ofAS/400.ExampleNone6.1.15 link-protocol sdlcSyntaxlink-protocol sdlcViewSynchronous interface viewParameterNoneDescriptionUsing the link-protocol sdlc command, you can configure SDLC as the link layerencapsulation protocol of synchronous interfaces.By default, the link layer protocol encapsulated at synchronous interface is PPP.SDLC is a link layer protocol related to SNA. Its working principle is very similar toHDLC. To allow DLSw to operate normally, the encapsulation protocol ofsynchronous interface link layer should be changed to SDLC.Notice that the SDLC link protocol can not load the IP protocol, therefore you shouldremove all of the commands related with IP, such as delete interface IP addressbefore encapsulating SDLC.ExampleNone108
