CSX WAN Configuration4-14Configuring the PPP ProtocolRemote MRUThe Remote MRU field displays the Maximum Receive Unit (MRU) establishedfor the remote interface at the other end of the PPP Link (the value that the localentity is using when sending packets to the remote PPP entity).Local —> Remote Comprs (Compression)By default, a PPP link must be able to transmit packets with two-octet PPPProtocol Field values; however to conserve bandwidth on low speed links, PPPwas designed to omit redundant data by allowing some PPP Protocol Field valuesto be compressed into a single octet that can be readily recognized from its two-octet form.The Local–>Remote Comprs configuration option indicates whether ProtocolField Compression (PFC) is Enabled or Disabled at the local PPP entity when ittransmits packets to the remote PPP entity. Packets with compressed ProtocolField values must not be transmitted until this value has been negotiated betweenboth PPP entities.Remote —> Local Comprs (Compression)This configuration option indicates whether Protocol Field Compression (PFC) isEnabled or Disabled at the remote PPP entity when it transmits packets to thelocal PPP entity. Packets with compressed Protocol Field values must not betransmitted until this value has been negotiated between both PPP entities.Tx FCS SizeThe size of the Frame Check Sequence (FCS) in bits that the local node willgenerate when sending packets to the remote node. The value of this object ismeaningful only when the link has reached the open state. 16 bits is the only FCSsize supported.Rx FCS SizeThe size of the Frame Check Sequence (FCS) in bits that the remote node willgenerate when sending packets to the local node. The value of this object ismeaningful only when the link has reached the open state.Link Control Protocol Configuration FieldsThe LCP Configuration section shows parameters which will be communicatedby LCP during the link establishment phase between the CSX’s local interfacesand the remote interfaces at the other end of the link, and lets you alter thoseparameters at the local interfaces, if necessary.If#The SNMP MIB-2 ifIndex of the physical interface on the CSX at which the PPP-Link is configured.
