These release notes for the Cisco 6400 node route processor (NRP) support Cisco IOS Release 12.0DC, up to and including Release 12.0(5)DC. These release notes are updated as needed to describe new features, memory requirements, hardware support, software platform deferrals, and changes to the microcode or modem code and related documents.
For a list of the software caveats that apply to Release 12.0(5)DC, see the "Caveats" section and Caveats for Cisco IOS Release 12.0 T . The caveats document is updated for every maintenance release and is located on Cisco Connection Online (CCO) and the Documentation CD-ROM.
Use these release notes in conjunction with the cross-platform Release Notes for Cisco IOS Release 12.0 located on Cisco Connection Online (CCO) and the Documentation CD-ROM.
These release notes discuss the following topics:
This section describes the system requirements for the Cisco 6400 UAC NRP and includes the following sections:
Table 1 describes the memory requirements for the Cisco 6400 NRP.
| Platforms | Image Name | Minimum Required Flash Disk | Required Main Memory | Runs from |
|---|---|---|---|---|
Cisco 6400 NRP | c6400r-g4p5-mz | 8 MB Flash | 64 MB DRAM | RAM |
Cisco 6400 NRP | c6400r-g4p5-mz | 16 MB Flash | 64 MB DRAM | RAM |
Cisco IOS Release 12.0(5)DC supports the Cisco 6400 NRP. For detailed descriptions of the new hardware features, see the "New and Changed Information" section.
Cisco IOS Release 12.0(5)DC works with the Cisco Service Selection Dashboard, version 2.1.
A Cisco 6400 NRP with Release 12.0(5)DC software requires the use of Cisco IOS Release 12.0(4)DB or greater for the Cisco 6400 node switch processor (NSP). If you want to use the combined network management Ethernet (NME) interface features, you must use Cisco IOS Release 12.0(5)DB for the NSP. For information about Release 12.0DB for the NSP, see Release Nodes for Cisco 6400 Node Switch Processor (NSP) for Cisco IOS Release 12.0(5)DB .
To determine the version of Cisco IOS software currently running on your router, log on to the Cisco 6400 NRP and enter the show version EXEC command:
router> show version
An output appears similar to the following. The Cisco IOS version appears in the second line.
Cisco Internetwork Operating System Software IOS (tm) 6400 Software (c6400r-g4p5-mz), Version 12.0(5)DC.......
The output includes additional information including processor revision numbers, memory amounts, hardware IDs, and partition information. To upgrade to a new software release, see the "Cisco Connection Online" section.
The Cisco IOS software is packaged in feature sets (also called software images) depending on the platform. Each feature set contains a specific set of Cisco IOS features. The following section lists the feature set matrix and the features supported by each feature set. The Cisco 6400 NRP can only use a single image called c6400r-g4p5-mz. Table 2 lists features supported by the Cisco 6400 NRP image.
The following sections list the new features supported by the Cisco 6400 NRP in Cisco IOS Release 12.0(5)DC.
The Cisco 6400 NRP supports the use of layer 2 tunnel protocol (L2TP), an extension to the PPP protocol used for virtual private networks (VPNs). Release 12.0(5)DC supports L2TP with up to 400 sessions and up to 25 tunnels. For more information about L2TP, see the Layer 2 Tunnel Protocol feature module.
The combined network management Ethernet (NME) interface allows the entire Cisco 6400 system, including the NSP and all installed NRPs, to be managed through a single Ethernet interface. The NME interface eliminates the need for Ethernet cables and connections on individual NRPs.
Use of the combined NME interface requires Cisco IOS Release 12.0(5)DB for the NSP. See "Software Compatibility" section for more information.
For more information about using the combined NME interface, see "Configuring the NSP" and "Configuring the NRP" in the Cisco 6400 UAC Software Configuration Guide .
RADIUS Virtual Circuit (VC) Logging allows the Cisco 6400 Universal Access Concentrator to accurately record the virtual path interface (VPI) and virtual circuit interface (VCI) of an incoming subscriber session. With RADIUS VC Logging enabled, the RADIUS network access server (NAS) port field is extended and modified to carry VPI/VCI information.This information is logged in the RADIUS accounting record created at session startup. For more information about RADIUS VC logging, see the RADIUS VC Logging feature module.
IP Control Protocol (IPCP) subnet mask support allows customer premise equipment (CPE) to connect to the Cisco 6400 NRP and obtain an IP address and subnet mask range which it can use to populate its DHCP server database. To enable IPCP subnet mask support, you must specify a value for the Framed-IP-Netmask attribute (IETF RADIUS attribute 9) in the RADIUS user profile.
Using IPCP, the Cisco 6400 brings up PPP sessions with the CPE and authenticates each CPE as a separate user. The Cisco 6400 adds a static route for the IP address with the mask specified. If the netmask is specified in the user profile, the Cisco 6400 passes the IP netmask value and the IP address to the CPE during IPCP negotiation. The CPE uses the netmask to calculate an IP address pool from which IP addresses are assigned to PCs using the access link.
The ATM routed bridge encaps feature on the Cisco 6400 NRP is used to route IP over bridged RFC 1483 Ethernet traffic from a stub bridged LAN. Bridged IP packets received on an ATM interface configured in route-bridged mode are routed via the IP header. Such interfaces take advantage of the characteristics of a stub LAN topology and offer increased performance and flexibility over integrated routing and bridging (IRB). For more information about ATM routed bridge encaps, see the ATM Routed Bridge Encaps feature module.
Enhancements to the Cisco 6400 NRP Service Selection Gateway (SSG) include IOS network address translation (NAT), support for Cisco Express Forwarding (CEF), VPI/VCI indexing to service profile, and RADIUS interim accounting record generation. For more information about SSG enhancements, see the Node Route Processor-Service Selection Gateway Enhancements feature module.
The Cisco 6400 NRP now supports Point-to-Point Protocol over Ethernet (PPPoE), which allows you to configure PPP over Ethernet on ATM using a virtual circuit (VC) multiplexed encapsulation mode. Using a PPPoE client, a PPP session can be initiated on a simple bridged Ethernet connected client through a standard Digital Subscriber Line (DSL) modem. The session is transported over the ATM DSL link via RFC 1483 Ethernet bridged frames and terminated in the Cisco 6400 NRP. The Cisco 6400 NRP does not support PPPoE on the Fast Ethernet port.
For more information about PPPoE, see the PPP over Ethernet feature module.
The Node Route Processor-Service Selection Gateway (NRP-SSG) is a switching solution for service providers who offer intranet, extranet and Internet connections to subscribers using high-speed data circuit equipment (DCE) such as Asymmetric Digital Subscriber Line (ADSL) equipment to allow simultaneous access to network services. The NRP-SSG allows the Cisco 6400 to act as a central control point for Layer 2 and Layer 3 services. This can include services available through ATM VCs, virtual private dial-up networks (VPDNs) or normal routing methods. The NRP-SSG feature is designed to work with the Cisco Service Selection Dashboard version 2.1 for Layer 3 services available on CCO.
For more information about the Service Selection Gateway, see the Node Route Processor ---Service Selection Gateway feature module
This section contains open caveats for the current Cisco 6400 NRP release only. Caveats in Cisco IOS Release 12.0 also apply to Release 12.0(5)DC. For information about caveats in the Cisco IOS Release 12.0, refer to the "Caveats" sections in the Cross-Platform Release Notes for Cisco IOS Release 12.0 document located on CCO and the Documentation CD-ROM.
In addition, caveats from Cisco IOS Release 11.3(9)DB and 12.0(3)DC also apply to Release 12.0(5)DC. Information regarding these caveats can be found in Release Notes for Cisco 6400 NRP for Cisco IOS Release 11.3(9)DB and Release Notes for Cisco 6400 NRP for Cisco IOS Release 12.0(3)DC , respectively.
This section describes possibly unexpected behavior by Release 12.0(5)DC. This section describes severity 1, 2, and selected severity 3 caveats.
