Features in 54266-01

Patch 54266-01 includes the following enhancements and resolved issues:

PCR: 40563

Module: ADSL

This patch, together with the base software release, supports the AR441S ADSL (Annex B) router. With this patch, the AR440S ADSL port operates in Annex A mode for ADSL over POTS, and the AR441S ADSL port operates in Annex B mode for ADSL over ISDN.

PCR: 40568 Module: SWKLevel: 3

If the Jabber counter in the output of the show switch port counter command had more than four digits, it displayed an incorrect value. This issue has been resolved.

PCR: 40572

Module: M8272

Level: 3

An AR023 synchronous port interface card (PIC) installed in an AR440S failed the Test facility interface test, even when there was nothing wrong with the PIC. This issue has been resolved.

PCR: 40576

Module: Firewall

Level: 2

When the firewall was creating new NAT entries under extremely heavy loads, it occasionally caused a fatal error. This issue has been resolved.

PCR: 40581 Module: BRG

Level: 2

The router could not bridge between an ATM channel and a VLAN interface. This issue has been resolved.

PCR: 40582 Module: BRG

Level: 2

Occasionally a reboot occurred when the router attempted to bridge traffic to an ATM channel before the channel had come up for the first time. This issue has been resolved.

PCR: 40585

Module: IPG

Level: 2

Attaching an IP interface to a VCMux encapsulated ATM interface with

Inverse ARP disabled by using the command:

add ip interface=atm0.1 ipaddress=192.168.1.1 inversearp=off

failed, giving one of the messages:

Error (3005271): Internal Error: Failed to start interface

Error (3005271): Internal Error: Failed to set interface

This issue has been resolved. It is now possible to add an IP address to a VCMux encapsulated ATM interface with inversearp set to off. This is known as RFC 1483 routing. RFC 1577, classical IP and ARP over ATM, still requires the ATM interface to be LLCSNAP encapsulated.
