4. ADTRAN IQ PRODUCTS USER MANUAL ADDENDUM This addendum describes the Layer 3 and Top Talker monitoring capabilities recently added to the ADTRAN IQ Frame Relay Product Family These features allow you to gather protocol specific statistics providing information concerning traffic utilization in the frame relay connection This information allows network managers to determine if certain traffic is dominating the frame relay connection without the cost of an expensive probe All information can be gathered by management systems and used to monitor network health and perform long term network planning allowing optimum use of network resources The following sections describe the configuration selections and statistical information related to Layer 3 monitoring CONFIGURATION SELECTIONS Protocol 1 Protocol 2 Access the configuration selections for the Layer 3 capabilities by selecting CONFIGURATION gt SYSTEM gt PROTOCOL 1 or PROTOCOL 2 These selections allow you to arm the IQ Product to gather statistics for particular protocols Select the protocol types most commonly found on your network If you have only one type set PROTOCOL 1 for that type and set PROTOCOL 2 for UNKNOWN The information is displayed in the LAYER 3 portion of the STATISTICS menu see the following section Layer 3 Statistics Descriptions for each of the six selections follow None Statistics are not gathered for that protocol number IP Statistical i
