Table 1 Memory Recommendations for the Cisco 6400 Aggregator 

Product Name	Software Module Description	Image Name	Recommended Minimum DRAM Memory	Recommended Minimum Flash Memory
NRP	Boot image	c6400r-boot-mz	—	—
NRP-2 and NRP-2SV	IOS NRP-2 base IOS NRP-2 mutlidomain IOS NRP-2 web selection	c6400r2sp-g4p5-mz	256 MB for up to 6500 sessions. 512 MB for over 6500 sessions.	—
NRP-1	IOS NRP-1 base IOS NRP-1 multidomain IOS NRP-1 web selection	c6400r-g4p5-mz	64 MB for up to 750 sessions. 128 MB for over 750 sessions.	8 MB
NSP		c6400s-wp-mz c6400s-html.tar	The standard 64 MB DRAM memory configuration supports up to 12K virtual circuits (VCs). 128 MB DRAM is recommended for supporting up to 32K VCs or for using ATM RMON or ATM Accounting. 128 MB DRAM is also recommended if you are upgrading from an earlier release to Cisco IOS Release 12.1(5)DB.	20 MB or 32 MB1 350 MB recommended for NRP-2 configurations

1 The 20-MB Flash disk is no longer available; the 32-MB Flash disk is now the default Flash configuration.

---

Note In most NRP-2 configurations, 256-MB DRAM is adequate for up to 6500 sessions. If you have more sessions, the requirement is 512-MB DRAM.

---

---

Note When you are running multicast in an NRP-2 configuration, the NRP-2 should have 512 MB of memory.

---

---

Note In most NRP-1 configurations, 64-MB DRAM is adequate for up to 750 sessions. If you have more sessions, you need 128-MB DRAM. If you are using the NRP-1, for an upgrade from an earlier release to Cisco IOS Release 12.2(2)B7, 128-MB DRAM is recommended.

---

Supported Hardware

Cisco IOS Release 12.2(2)B7 supports the Cisco 6400 NRP-1, NRP-2, NRP-2SV, NSP, and NSP-S3B modules. The NSP-S3B, otherwise identical to the NSP, is required if you want to use the Building Integrated Timing Supply (BITS) Network Clocking software feature.

Software Compatibility

For NRP-Service Selection Gateway (SSG) users, Cisco IOS Release 12.2(2)B7 works with the Cisco Service Selection Dashboard (SSD) Releases 2.5(1) and 3.0(1), and Subscriber Edge Services Manager (SESM) Release 3.1(1).

Determining the Software Version

To determine the version of Cisco IOS software currently running on the Cisco 6400 NRP, log in to the NRP and enter the show version EXEC command:

Router> show version

Cisco Internetwork Operating System Software 

IOS (tm) C6400R Software (C6400R-G4P5-M), Version 12.2(2)B7

To determine the version of Cisco IOS software currently running on the Cisco 6400 NSP, log in to the NSP and enter the show version EXEC command:

Router> show version

Cisco Internetwork Operating System Software

New and Changed Information

This section describes new features available in Cisco IOS Release 12.2(2)B7 and enhancements to existing features offered in earlier releases.

There are no new hardware or software features supported by the Cisco 6400 aggregator in Cisco IOS Releases:

•12.2(2)B7

•12.2(2)B6

•12.2(2)B5

•12.2(2)B4

•12.2(2)B3

•12.2(2)B2

Limitations and Restrictions

•L2TP Multihop by remote tunnel hostname is not supported in Cisco IOS Release 12.2(2)B7. L2TP Multihop by domain is supported in Cisco IOS Release 12.2(2)B7 by entering the lcp renegotiation always command on the L2TP network server (LNS) vpdn-group.

•When you flap an ATM subinterface that has traffic shaping enabled, the NRP-2SV SAR can fail. If this occurs, all sessions will eventually timeout and disconnect. This issue can also occur when you change vc-class parameters. If you use traffic shaping and you need to change configurations related to virtual circuits with traffic shaping configured, you must shutdown the ATM main interface, make your configurations changes, then bring up the ATM main interface.

Important Notes

The following sections contain important notes about Cisco IOS Release 12.2(2)B7 that can apply to the Cisco 6400 aggregator.

Session and Tunnel Scalability

Table 4 shows the number of sessions and tunnels supported for the NRP modules in Cisco IOS Release 12.2(2)B7. While using NRP-SSG, Cisco IOS Release 12.2(2)B7 supports the number of sessions and tunnels shown in Table 5.

---

Note To support more than 750 sessions, the NRP-1 must have 128 MB DRAM.

---

---

Note In most NRP-2 configurations, 256 MB DRAM is adequate for up to 6500 (PPPoE) sessions. More sessions require 512 MB DRAM.

---

NRP-2SV Scalability Tuning Parameters

Following are scalability tuning parameter values used during testing for 8000 PPPoA sessions and 2000 L2TP tunnels. These parameters prevent known issue CSCdu86416 from occurring.

interface Virtual-Template1

keepalive 200

ppp timeout retry 25

ppp timeout authentication 20

vpdn-group 1

l2tp tunnel hello 150

l2tp tunnel receive-window 500

l2tp tunnel nosession-timeout 20

l2tp tunnel retransmit retries 12

l2tp tunnel retransmit timeout min 4

l2tp tunnel retransmit timeout max 6

Following is the hold-queue CLI used during testing.

interface ATM0/0/0

 no ip address

 load-interval 30

 atm vc-per-vp 2048

 no atm ilmi-keepalive

 hold-queue 4096 in

 hold-queue 4096 out

end

---

Tip With PPPoA over L2TP network architecture, a few PPP sessions may not have IP addresses allocated during system reboot or interface flapping. If you encounter this problem, configure ppp ncp timeout in the template on LNS as shown here:

interface Virtual-Template1
ppp timeout ncp 60

It is important to note a potential negative impact on PPPoX termination scenarios:

The default is no time-out at all. Configuring ppp timeout ncp 60 tells the router if NCP cannot be established within 60 seconds to tear down LCP and start all over again.

Note that you should only configure ppp timeout ncp 60 if you encounter the IP address allocation problem described here. Do not configure the timeout indiscriminately or to any local termination PPPoA/PPPoE deployment.

---

---

Note In most NRP-2 configurations, 256 MB DRAM is adequate for up to 6500 (PPPoE) sessions. More sessions require 512 MB DRAM.

---

---

Note The default threshold at which Cisco IOS declares a process to have run "too long" is too short for some Cisco IOS processes, when very large numbers of sessions are established on the NRP-2. Use the command scheduler max-task-time 20000 to increase the default threshold. This will avoid unnecessary "CPUHOG" messages.

---

NRP-1 Scalability Tuning Parameters

This section describes the scalability tuning parameters that should be used for running large numbers of sessions on the NRP-1.

interface ATM0/0/0

 hold-queue 1000 in

 hold-queue 1000 out

!

interface Virtual-Template1

 keepalive 120

 ppp max-configure 255

 ppp timeout retry 15

 ppp timeout authentication 15

DHCP Option 82 Support for Routed Bridge Encapsulation

The DHCP Option 82 Support for RBE feature provides support for the Dynamic Host Configuration Protocol (DHCP) Relay Agent Information Option (Option 82) when using ATM RBE.

Service providers are increasingly using ATM RBE to configure DSL access. The DHCP Option 82 Support for RBE feature enables those service providers to use DHCP to assign IP addresses and DHCP Option 82 to implement IP address assignment policies such as limiting the number of IP addresses on specific ports on specific ports or ATM VCs.

The DHCP Relay Agent Information Option enables a DHCP relay agent to insert information about itself when forwarding client-originated DHCP packets to a DHCP server. The DHCP server can use this information to implement IP address or other parameter-assignment policies.

The DHCP Option 82 Support for RBE feature uses a suboption of the DHCP Relay Agent Information Option called Agent Remote ID. The Agent Remote ID suboption enables the DHCP relay agent to report the ATM RBE subinterface port information to the DHCP server when a DHCP IP address request is processed through the ATM RBE subinterface. The DHCP server can use the ATM RBE subinterface information for making IP address assignments and security policy decisions.

Obtaining Technical Assistance

Cisco provides Cisco.com as a starting point for all technical assistance. Customers and partners can obtain online documentation, troubleshooting tips, and sample configurations from online tools by using the Cisco Technical Assistance Center (TAC) Web Site. Cisco.com registered users have complete access to the technical support resources on the Cisco TAC Web Site.

Cisco.com

Cisco.com is the foundation of a suite of interactive, networked services that provides immediate, open access to Cisco information, networking solutions, services, programs, and resources at any time, from anywhere in the world.

Cisco.com is a highly integrated Internet application and a powerful, easy-to-use tool that provides a broad range of features and services to help you with these tasks:

•Streamline business processes and improve productivity

•Resolve technical issues with online support

•Download and test software packages

http://www.cisco.com

Technical Assistance Center

The Cisco Technical Assistance Center (TAC) is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two levels of support are available: the Cisco TAC Web Site and the Cisco TAC Escalation Center.

Cisco TAC inquiries are categorized according to the urgency of the issue:

•Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.

•Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.

•Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.

•Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

The Cisco TAC resource that you choose is based on the priority of the problem and the conditions of service contracts, when applicable.

Cisco TAC Web Site

You can use the Cisco TAC Web Site to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to this URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to this URL to register:

http://www.cisco.com/register/

If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco TAC Web Site, you can open a case online by using the TAC Case Open tool at this URL:

http://www.cisco.com/tac/caseopen

If you have Internet access, we recommend that you open P3 and P4 cases through the Cisco TAC Web Site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.

To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to this URL:

http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml

Before calling, check with your network operations center to determine the level of Cisco support services to which your company is entitled: for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). When you call the center, have available your service agreement number and your product serial number available.
