9-24 Frame Relay Module 4.0 User Guide, Rev 01N3is the number of Information LPDUs that will be received before the local node sendsan acknowledgment. This parameter is used in conjunction with T2 to allow stationsto reduce traffic. A counter is initialized to N3 , and will be decremented by one eachtime a valid sequential Information LPDU is received. When the counter reaches 0 anacknowledgment will be sent.N3 will be reset whenever an Information or Supervisory acknowledgment LPDU issent by the local node.Twis the maximum number of sequentially numbered Information LPDUs that the localnode can have outstanding. If Tw is reached, and acknowledgment will be sent.N2is the maximum number of times that an LPDU (including Information LPDUs resentafter a checkpoint operation) will be sent following expiration of T1.Priorityprioritizes intra-nodal traffic; the higher the number, the higher the priority. (This pri-ority has no effect on traffic exiting a node.)Priorities are configured on all logical interfaces that use a physical frame relay port.The device processor in the node uses these priorities to help determine the order inwhich it will process protocols.When configuring priorities, be careful to consider the types oftraffic being routed on other connections in the node.Bandwidth Allocation Groupassigns the LLC2 host to one of sixteen groups whose parameters regulate bandwidthusage. See "Configuring Bandwidth Allocation Groups" on page 7-6.Routing Subscriber IDassociates a Subscriber ID with the LLC2 host, and partially defines the local sub-scriber IDs, all of which must begin with the Routing Subscriber ID.Source MAC Address Maskis used to identify the FRM to inbound frames from a local LAN in an OriginatedLLC2 session. Source address masks and host MAC addresses are placed in a for-warding list that is checked by the software when a frame is received. If the MACaddress in an incoming frame matches a configured Source MAC Address Mask, theframe will be passed through the node for transmission out the frame relay interface.On-Line Temporary Changesdetermines whether changes made will affect the Database or System Memory values(Database values exist in the software, and are recorded as System Memory valueswhen the FRM is booted.) If On-Line Temporary Changes is set to N, the Databasevalue will change. If Y, the System Memory value will change. Pressing [F7] afterchanging either set of values will propagate the change to the other set. (This must bedone at each screen, and affects only those parameters on that screen.)
