About the FrameSaver SLV 9124

FrameSaver SLV 9124 Features

The FrameSaver SLV 9124 unit provides the following features:

H Intelligent Service Level Verification. Provides accurate throughput,

latency, and availability measurements to determine network performance and whether service level agreements (SLAs) are being met, along with SLA reporting. SLA parameter thresholds can be configured to provide proactive notification of a developing network problem.

H Security. Provides multiple levels of security to prevent unauthorized access

to the unit.

H TruePutt Technology. Using Frame Delivery Ratios (FDR) and Data

Delivery Ratios (DDR), throughput (within and above CIR, as well as between CIR and EIR, and above EIR) can be measured precisely, eliminating inaccuracies due to averaging. These ratios are available through OpenLane SLV reports.

H Frame Relay Aware Management. Supports diagnostic and network

management features over the frame relay network using the Annex-A, Annex-D, and Standard UNI (User Network Interface) LMI management protocol. The unit’s frame relay capability also supports:

— Inband management channels over the frame relay network using

dedicated PVCs.

— Unique nondisruptive diagnostics. — CIR monitoring on a PVC basis. — Multiple PVCs on an interface. — Multiplexing management PVCs with user data PVCs. — Multiplexing multiple PVCs going to the same location onto a single

network PVC.

H Auto-Configuration. Provides the following automatic configuration features:

— Frame Relay Discovery – For automatic discovery of network DLCIs and

configuration of a user data port DLCI, the PVC connection, and a management PVC, which is multiplexed with user data DLCIs.

— LMI Protocol Discovery – For automatic configuration of the protocol

being used by the network.

— DLCI Deletion – For automatic removal of configuration of unused DLCIs

from the unit’s configuration and statistical databases.

— CIR Determination – For automatic recalculation of the committed rate

measurement interval (Tc) and excess burst size (Be) when a DLCI’s CIR changes.

Excess burst size (Be) and committed burst size (Bc) are recalculated when Committed Burst Size Bc (Bits) is set to CIR. The committed rate measurement interval (Tc) is recalculated when Committed Burst Size Bc (Bits) is set to Other.

About the FrameSaver SLV 9124

H RMON-Based User History Statistics Gathering. Provides everything

needed to monitor network service levels, plus throughput with accurate data delivery, network latency , and LMI and PVC availability.

In addition, port bursting statistics are kept for all frame relay links. These statistics are available real-time via the Enterprise MIB and historically as an RMON2 User History object. In future releases of the OpenLane SLM system, this will enable even more accurate calculations of utilization.

H Network User History Synchronization. Allows correlation of RMON2 User

History statistics among all SLV devices in a network for more accurate OpenLane SLV reports. Using a central clock, called the network reference time, all SLV device user history statistics are synchronized across the network, further enhancing the accuracy of OpenLane SLV reports.

H Extensive Testing Capability. Provides a variety of tests to identify

and diagnose device, network, and other problems. These tests can be commanded from the unit’s menu-driven user interface or the OpenLane system (using its easy-to-use Diagnostic Troubleshooting feature).

These tests include V.54 or FT1-ANSI data channel loopback support so the frame relay network service provider can perform a physical loopback from its own switch without having to contact the leased line provider for loopback activation.

H Dedicated Troubleshooting PVC. Provides a troubleshooting management

link that helps service providers isolate problems within their network. This feature can be configured.

H LMI Packet Capture. Provides a way to upload data that has been captured

in a trace file so the data can be uploaded and transferred to a Network Associates Sniffer for analysis, or viewed via the menu-driven user interface. The 12 most recent LMI messages can be displayed from the menu-driven user interface.

H Maximum Number of PVCs and Management PVCs Supported.

H Router-Independence. Unique diagnostics, performance monitoring,

PVC-based in-band network management, and SNMP connectivity is not dependent upon external routers, cables, or LAN adapters.

H Inverse ARP and Standard RIP Support. Provides Inverse ARP (Address

Resolution Protocol) support so the frame relay router at one end of a management PVC can acquire the IP address of a FrameSaver unit at the other end of the PVC. Standard RIP (Routing Information Protocol) allows the router to automatically learn the routes to all FrameSaver units connected to that FrameSaver unit.

About the FrameSaver SLV 9124

H Configuration Upload/Download and Software Download Capability.

Provides quick transfer of configuration options to and from nodes and software downloads while the unit is running using the standard File Transfer Protocol (FTP). Two software images can be stored.

H Dual Flash Memory. Allows software upgrades while the unit is up and

running. Two software loads can be stored and implemented at the user’s discretion.

H ATM VPI/VCI and DLCI Correlation. For networks with both ATM and frame

relay-access endpoints, allows the FrameSaver unit to report the originating Virtual Path or Channel Identifier (VPI/VCI) in the far-end ATM-access endpoint where the local DLCI is mapped so they can be correlated for OpenLane SLV reports.

H Back-to-Back Operation. Allows two FrameSaver devices to be connected

via a leased-line network or simulation so a point-to-point configuration can be implemented.

H OpenLane Service Level Management Solution. Provides an

advanced, standards-based performance monitoring and management application.

Being standards-based, the OpenLane SLM system can also be used with other management applications like HP OpenView or IBM’s NetV iew. OpenLane includes HP OpenView adapters for integrating OpenLane features with the OpenView Web interface.

Being Web-based, the OpenLane system provides Web access to the data contained in the database to provide anytime, anywhere access to this information via a Web browser.

Some of the OpenLane SLM system’s features include:

— Real-time performance graphs provide exact performance measurement

details (not averages, which can skew performance results) of service level agreement (SLA) parameters.

— Historical SLV graphs provide service level management historical

reports so frame relay SLAs can be verified.

— Diagnostic troubleshooting provides an easy-to-use tool for performing

tests, which include end-to-end, PVC loopback, connectivity, and physical interface tests.

— Basic configuration allows you to configure FrameSaver devices, and set

RMON alarms and thresholds. Network DLCI Circuit IDs can also be assigned.

— Automatic SLV device and PVC discovery allows all SLV devices with

their SLV Delivery Ratio configuration option enabled to be discovered automatically, along with their PVCs.

— A FrameSaver unit can be reset from the OpenLane system. — Firmware downloading provides an easy-to-use tool for downloading to

an entire network or a portion of the network.

— On-demand polling of FrameSaver devices, and SNMP polling and

reporting are available.

H NetScout Manager Plus and NetScout Probe Support. Provides complete

LAN and WAN traffic analysis and monitoring functions for FrameSaver SLV devices. The following features are supported using this application:

— Thresholds for RMON 1 (Remote Monitoring, Version 1) alarms and

events can be configured.

— Performance monitoring can be performed using collected RMON 2

(Version 2) data. NetScout Manager Plus’s Protocol Directory and Distribution functionality allows FrameSaver devices to measure up to eleven network-layer protocols and report the amount of traffic generated by each. Its IP Top Talkers and Listeners reporting identifies the devices using network bandwidth for traffic and protocol analysis, identifying the network’s top six users. In addition, it collects performance statistics from FrameSaver devices. Up to 900 samples can be stored in 15-minute buckets, with 96 buckets in a 24-hour period, for up to five days worth of data.

— Optional standalone NetScout Probes can be used with FrameSaver

devices at sites where full 7-layer monitoring, an unlimited number of protocols, and advanced frame capture and decode capabilities are desired.

Selecting a Frame Relay Discovery Mode

When a Frame Relay Discovery Mode is active, the FrameSaver unit “discovers” network DLCIs from the network LMI status response message. It configures a network DLCI, a user data port DLCI, and automatically connects them to create a PVC.

Main Menu →Auto-Configuration →Frame Relay Discovery Mode

Automatically configured network DLCIs are multiplexed, and each automatically configured port DLCI carries the same DLCI Number as its corresponding network DLCI. These are the same DLCI numbers that would have been available had the FrameSaver unit not been inserted in the link, between your equipment and the network.

NOTE:

A local Management PVC (e.g., the PVC between the router and the FrameSaver unit’s user data port) must be configured manually; it cannot be configured automatically (see Setting Up Local Management at the

Central Site).

Setting Up Management

FrameSaver units are already set up for SNMP management, with Community Name 1 set to Public and Name 1 Access set to Read/Write. For remote sites, other than the IP Address, this is all that is required.

Configuration →Management and Communication → General SNMP Management

See Table 3-13, General SNMP Management Options, for configuration information. For the central site, local management between the unit and the router must be set up, as well (see Setting Up Local Management at the Central Site).

Setting Up Local Management at the Central Site

Set up a local management PVC between the central site unit and its router for local management control by the end-user customer.

" Procedure

To set up management through the router:

1. Create a DLCI that will be used for management on the user data port.

LMI Behavior Possible Settings: Independent,

Port-1_Follows_Net1-FR1, Net1-FR1_Follows_Port-1, Port-1_Codependent_with_Net1-FR1

Default Setting: Independent Configures the device to allow the state of the LMI to be passed from one interface to

another, determining how the unit will handle a change in the LMI state. Sometimes referred to as LMI pass-through.

Independent – Handles the LMI state of each interface separately so that the LMI state of one interface has no effect on the LMI state of another interface. Provides LMI Spoofing. This is the recommended setting when backup is configured, and for Network Service Providers (NSPs).

Net1-FR1_Follows_Port-1 – Brings LMI down on the network interface when LMI on Port-1 goes down, disabling the network interface and deasserting its control leads. When LMI on Port-1 comes back up, the network interface is reenabled. The LMI state on the network interface has no effect on the LMI state on Port-1. That is, the network interface’s LMI follows Port-1’s LMI. Used at central sites, this setting is useful when the remote site router on the other end of the PVC connection can initiate recovery via a redundant central site when there is a catastrophic central site LAN or router failure. Not recommended for NSPs.

Port-1_Follows_Net1-FR1 – Brings LMI down on Port-1 when LMI on the network interface goes down, disabling Port 1 and deasserting its control leads. When LMI on the network interface comes back up, Port-1 is reenabled and its control leads are reasserted. The LMI state on Port-1 has no effect on the LMI state on the network interface. That is, Port-1’s LMI follows the network interface’s LMI. This setting is useful if the router connected to Port-1 is used to initiate recovery when network failures are detected.

Port-1_Codependent_with_Net1-FR1 – Brings LMI down on the network interface when LMI on Port-1 goes down (or LMI down on Port-1 when LMI on the network interface goes down), and allows LMI to come back up when LMI comes back on the other interface. That is, the LMI state for one interface is dependent on the other. Use this setting when backup is through the router instead of the unit. It is not recommended since it makes fault isolation more difficult.

Configuration

When a CGA condition (LOS, OOF, or AIS) is declared for a T1 interface, the signaling bits being transmitted to the other T1 interface for the DS0 are forced to idle for two seconds (except for user-defined patterns which are transmitted immediately). This drops any call in progress. The signaling bits are then forced to the selected state (Busy or Idle), and remain in this state until the CGA condition clears. At this point, the received signaling bits from the T1 interface which formerly had the CGA condition are passed through to the other T1 interface.

NOTE:

Trunk conditioning will only occur on DS0s that are cross-connected to another T1 interface. All other DS0s remain unaffected by trunk conditioning.

Enter one of the values shown in Table 3-7 in each of the fields on both the Network side and the DSX-1 side. Although you can choose any value for the DSX-1 side, the default value displayed is based on a typical setting that would be used with the corresponding Network side value. Typical pairs of values are shown in the table below. If you change the Network side value, the DSX side value is changed to the corresponding default value.

LMI Protocol Possible Settings: Initialize_From_Net1FR1, Initialize_From_Interface,

Auto_On_LMI_Fail, Standard, Annex-A, Annex-D

Default Setting:

For user data port links: Initialize_From_Interface For network links: Auto_On_LMI_Fail

Specifies either the LMI protocol supported on the frame relay interface or the discovery source for the LMI protocol.

Initialize_From_Net1FR1 – The LMI type supported on this frame relay link will be configured to match the LMI protocol initially discovered on the primary Network frame relay link (Net1FR1). LMI Protocol is set to None internally , but once a protocol has become active or is set on the primary Network link, the protocol will be set to the same value on this link (Standard, Annex-A or Annex-D). The protocol will not be updated based on changes to Net1FR1 after being set initially .

Display Conditions – This option value only appears for a user data port.

Initialize_From_Interface – The LMI type supported on this frame relay link will be configured to match the LMI protocol discovered from the attached Network line or DTE device. Once a protocol has become active, the protocol will be set to the protocol discovered (Standard, Annex-A or Annex-D) on the frame relay link. The protocol will not be updated after being initially discovered. Frame relay links on user data ports discover the LMI protocol from an attached device via LMI status polls. Frame relay links on the network interface discover LMI protocol by sending polls to an attached Network line and “listening” for correct poll response messages.

Auto_On_LMI_Fail – The LMI type supported on this frame relay link will be configured to match the LMI protocol discovered from the attached Network line or the DTE device whenever an LMI Link Down failure occurs. This option is available for frame relay links on the Port and network interfaces. Frame relay links on user data ports discover the LMI protocol from LMI status polls by attached DTE devices. Frame relay links on the network interface discover LMI protocol by sending polls to an attached Network line and “listening” for correct poll response messages.

Standard – Supports Standard LMI and the Stratacom enhancements to the Standard LMI.

Annex-A – Supports LMI as specified by Q.933, Annex A. Annex-D – Supports LMI as specified by ANSI T1.617, Annex D
