About FrameSaver SLV In-Line Monitors

FrameSaver SLV In-Line Monitor Features

The FrameSaver SLV in-line monitor 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 FrameSaver SLV In-Line Monitors

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).

H Dedicated Troubleshooting PVC. Provides a troubleshooting management

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

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.

About FrameSaver SLV In-Line Monitors

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 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 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.

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.

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.

Using this special feature, you can set up two FrameSaver units that are connected back-to-back without frame relay switches between them, as in a test bench setup.

Changing Operating Mode

When setting up back-to-back operation:

H One unit must be configured for Standard operation, which is the setting for

normal operation.

H The other unit must be configured for Back-to-Back operation so it presents

the network side of the UNI (user-network interface).

Only one of the units will have its operating mode changed.

" Procedure

To set up back-to-back operation:

1. On the unit to be configured for Back-to-Back operation, manually configure DLCIs; DLCIs should be configured before connecting the two units.

2. Access the Change Operating Mode screen.

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 since it makes fault isolation more difficult.

This feature allows Telnet or FTP access to the unit on this link. Troubleshooting over this link is essentially transparent to customer operations. No alarms or SNMP traps are generated to create nuisance alarms for the customer.

TS_Management_Link is initially disabled in most models, but the link can be enabled at any time. Any valid network Management PVC created on a standard DLCI can be used. When enabled, a troubleshooting link can be accessed any time the service provider requests access. An assigned security level can also control access.
