Diagnostic Feature Set
The following feature set is common to all FrameSaver DSL devices. It provides
basic FrameSaver frame relay and diagnostic capability, which includes the
following features:
Easy Installation. When AutoBaud is used, no configuration is required.
SNMP options may be modified to provide security and enable traps.
Frame Relay Aware Management. Supports diagnostic and network
management features over the frame relay network. The device’s frame relay
capability also supports:
— Inband management channels over the frame relay network using
dedicated PVCs.
— Unique nondisruptive PVC (Permanent Virtual Circuit) diagnosti cs.
— Real-time end-to-end connectivity test and latency snapshots.
— Troubleshooting DLCI for service provider remote management.
— Basic frame relay statistics.
— Committed Information Rate (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.
Router-Independence. Remote access to diagnostics, performance
monitoring, PVC-based in-band network management, and SNMP
connectivity are not dependent upon external routers, cables, or LAN
adapters.
Security. Provides multiple levels of security to prevent unauthorized access
to the unit.
Dual Flash Memory. Allows software upgrades while the unit is running. Two
software loads can be stored and implemented at the user’s discretion.
Auto-Configuration. Provides the following automatic configuration features:
— CIR Determination – Recalculates 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.
Configurable FTP Transfer Rate. Allows control of the transmit rate used for
downloading from the FrameSaver unit and uploading user history statistics to
an NMS (Network Management System) via the COM port connection or a
management PVC. This allows the data to be transferred as a background
task using the standard File Transfer Protocol (FTP) over extended periods of
time using low bandwidth.
