1.  Feature Enhancements / Functional Changes

This release provides the following additional DSL Router key features:

• Transparent bridging (with spanning tree protocol availability) of all protocols in the service domain. Simultaneous routing of IP traffic with bridging of all other protocol traffic.
• Ethernet type and ICMP message type filter support for bridged and/or routed service domain traffic.
• Simultaneous Basic NAT and NAPT support.

This release contains the following functional changes:

New user interface commands supported (see user’s guide and online help command for details and command
syntax):
– bridge {disable | enable}
– bridge aging-timeout [time]
– bridge priority [priority]
– spanning-tree {disable | enable}
– show spanning-tree
– show bridge
– nat basic purge
– nat napt purge
– ip routing {disable | enable}
– packet processing {disable | enable}
NOTE: This command replaces ip processing {disable | enable}, but this command will continue to be supported
for backward compatibility.
Changes to existing user interface commands (see user’s guide and online help command for details and command
syntax):
– show statistiscs [eth1 | dsl1 | ip | bridge]
NOTE: The display of the Ethernet statistics (show statistics eth1) now includes counts of events that don’t
result in a frame discard, but are useful to know. These include the following events:
• Single Collision on Tx
• Multiple Collisions on Tx
• Late Collision on Tx
• No Carrier Detect on Tx
• Pauses on Tx
• Defers on Tx
– clear statistiscs [eth1 | dsl1 | ip | bridge]
– nat basic {disable | enable}
– nat napt {disable | enable}

• Support NAT/DHCP w/ public and priv IPs on E0
• User Level Traceroute and Ping
• NAT NAPT MAP command now passes traffic on layer 3 endpoints / Intermittent problem NAPT.

For proper operation with an 88xx/86xx DSLAM, this release requires an 8000 IP Conservative MCC, MCC Plus, or MCP with appropriate firmware:

 

Card Type	CCA #	DSLAM
6371 RADSL DSL Router	868-3628-8000	N/A
8373 RASDL 12 Port Card	868-4104-8100	8610, 8810, 8820
8374 RASDL 12 Port Card	868-4104-8100	8820 and 8620
8510 RADSL Port Card	868-3209-80xx (xx = 00, 01, 02, …)	8600, 8800, 8810, 8610, 8820
8000 IP Conservative MCC	868-3362-80xx (xx = 00, 01, 02, …)	8600, 8800, 8810
8000 IP Conservative MCC Plus	868-3882-80xx (xx = 00, 01, 02, …)	8600, 8800, 8810
8000 IP Conservative MCP	868-3883-80xx (xx = 00, 01, 02, …)	8610, 8620 and 8820

 

Card Type	CCA #	Firmware
8373 RASDL 12 Port Card	868-4104-8100	04.00.38 or greater
8374 RASDL 12 Port Card	868-4104-8100	04.00.38 or greater
8510 RADSL Port Card	868-3209-80xx (xx = 00, 01, 02, …)	04.00.38 or greater
8000 IP Conservative MCC	868-3362-80xx (xx = 00, 01, 02, …)	M04.00.38
8000 IP Conservative MCC Plus	868-3882-80xx (xx = 00, 01, 02, …)	M04.00.38
8000 IP Conservative MCP	868-3883-80xx (xx = 00, 01, 02, …)	M04.00.38

This firmware release supersedes all prior releases and is intended to replace firmware currently deployed in all 6371 RADSL DSL Routers.
When the router is upgraded to R3, the center two digits of the device’s model number will be changed to “A3” to reflect the current operating release level.
The factory default configuration is for bridging to be enabled and service domain IP routing to be disabled. However, upgrading existing routers will leave service domain IP routing enabled and bridging disabled.
It is recommended that the latest official release of the RADSL Line Card firmware be used for full feature compatibility.
Please refer to the RADSL Line Card release notes for information about compatibility with other port cards.

 It is recommended that the latest official release of the 8000 MCP card firmware be used for full feature compatibility.
Please refer to the MCP release notes for information about compatibility with other port cards.  In general, the management card firmware release needs to be the same as or newer than the newest firmware release on a port card in the DSLAM.

The following are known problems and limitations with this release:
1. NAT Doesn’t Support Out Of Order Fragments) Out of order fragment packets is not support by
the DSL Router R3 implementation of NAT. This means that it expects the first packet of a fragmented
stream to be received first prior to the receipt of any other packets of that stream.
2. Hotwire PC Download Program Not working with Windows 2000 (Windows 9x and Windoes NT 4.0 supported)
3. NAT NAPT Misconfiguration Resets Endpoint
