1. About the FrameSaver SLV
9128-A2-GB20-80 September 2002
1-7
Integral Modem.
Provides an internal 14.4 Kbps modem to support dialing in
to the unit for out-of-band management and automatic dialing out of SNMP
traps.
Modem PassThru.
Provides access to another device’s VT100-compatible
user interface over a dial connection. When this feature is enabled, a logical
connection between the unit’s modem and COM ports is created, allowing
access to a collocated device’s serial port via the FrameSaver unit’s internal
modem. This feature is sometimes referred to as the Router Assist feature.
Configurable FTP Transfer Rate.
Allows you to control the transmit rate
when downloading firmware into the FrameSaver unit and uploading user
history statistics to an NMS (Network Management System) via the COM port
connection or a management PVC so the data can be transferred as a
background task using the standard File Transfer Protocol (FTP) over
extended periods of time using low bandwidth.
RMON User History Performance Statistics via SNMP Polling.
Provides
access to the physical interface and basic frame relay performance statistics
by polling the FrameSaver unit using SNMP (Simple Network Management
Protocol). These statistics are available real-time via the Enterprise MIB and
historically as an RMON2 User History object.
Frame Relay Traffic Policing.
Ensures proper alignment and correlation of
CIR (Committed Information Rate) values between the FrameSaver unit and
the network switch. When this feature is enabled, the unit can enforce CIR and
EIR (Excess Information Rate), marking frames that exceed CIR as DE
(Discard Eligible) using the same method used by the switch.
Service Provider Support.
Provides information and tools useful to network
service providers, which includes the following:
— IP Routing Table – Shows the IP routing table for the FrameSaver unit,
with network as well as host routes, the number of hops to the destination,
the method by which the route was added to the table, the interface used
to get to the destination, and how long the route has been in existence.
— Trap Event Log – Displays the SNMP (Simple Network Management
Protocol) trap event log for the FrameSaver unit from the menu-driven user
interface, with the most recent events first, keeping a running total for all
trap events stored, the amount of time since the event was logged, plus a
description of the trap.
— Troubleshooting PVC – Provides a dedicated troubleshooting
management link that helps service providers isolate problems within their
network.
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 and 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.
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.
