Stinger® IP2000 Configuration Guide xiii

About This Guide

A Stinger unit with the IP2000 control module (a Stinger IP2000) supports identical
Asynchronous Transfer Mode (ATM) capabilities to those in Stinger units with the
standard control module. In addition, a Stinger IP2000 can terminate IP traffic and
forward it across a built-in Gigabit Ethernet interface.

Note Instructions for installing and configuring the management functions of the

IP2000 are found in the Getting Started Guide for your Stinger platform.

What is in this guide

This guide focuses on the aspects of Stinger configuration that are specific to IP2000
control module capabilities. To fully configure the system for both ATM and IP
capabilities, use this guide with the Stinger ATM Configuration Guide.

Note You can configure the amount of bandwidth allocated to LIM interfaces and

control modules for carrying upstream traffic. For details about that aspect of using
the IP2000 control module, as well as for ATM quality of service (QoS) and other
traffic management capabilities, see the Stinger ATM Configuration Guide.

This guide describes how to configure IP routing and related functions in the Stinger
Stinger. It includes information about local and global network IP issues, as well as
how to configure both IP-routed switch-through ATM permanent virtual circuits
(PVCs) and RFC 1483 PVCs.

This guide also describes how to set up IEEE 802.1Q virtual local area network
(VLAN) support on the Gigabit Ethernet interface, and how to configure the system
to support multicast video over DSL with Internet Group Management Protocol
(IGMP) version-1 or version-2 messaging.

Warning Before installing your Stinger unit, be sure to read the safety instructions

in the Edge Access and Broadband Access Safety and Compliance Guide. For information
specific to your unit, see the “Safety-Related Physical, Environmental, and Electrical
Information” appendix in the Getting Started Guide for your Stinger unit.

Network architecture overview

Network architecture overview

A Stinger IP2000 supports all standard Stinger ATM features, such as data and voice
services over DSL. In addition, it supports IP services such as multicast video, unicast
video-on-demand, and other video and IPTV applications. The services supported by
the IP2000 are provided downstream to DSL subscribers. In the upstream direction,
DSL subscribers accessing the Stinger IP2000 via IP over ATM can be directly routed
via the IP infrastructure to Internet services.

A Stinger IP2000 supports IP routing, ATM quality of service and traffic shaping,
virtual LAN, and multicasting capabilities to provide fast, efficient access to ATM and
IP services.

Multicast video

A Stinger IP2000 uses the Internet Group Management Protocol (IGMP) to manage
group memberships of downstream video to a PC application or set-top box, as
shown in Figure 1-1. Administrators can configure levels of service that control
subscribers’ access to specific multicast groups. Connection to originating router can
be across the Gigabit Ethernet interface or through a high-speed IP over ATM
connection.

Multiplexing multiple IP flows on a single ATM VCC

A Stinger IP2000 supports an implementation of Class of Service (CoS) that co-exists
with the Stinger ATM QoS implementation. This feature allows transferring multiple
IP video streams (multicast and unicast) over single user-side ATM virtual circuit.

The proprietary CoS implementation enables the delivery of differentiated services
over an IP infrastructure. All traffic handled by the IP2000, whether encapsulated IP
or native ATM, passes through the network processor function.

Non-IP terminated ATM traffic, including operations, administration, and
maintenance (OAM) F5 traffic, is treated as highest priority and handled in an AT M
pass-through mode. This traffic passes through the network processor with no further
processing.

RFC 1483 IP traffic that terminates on the IP2000 is reassembled from ATM cells into
IP packets. It is then classified and assigned to priority output queues. Per-VC strict­priority queuing is supported with three priority levels as described in Table 1-2.

Per-VC queuing operates in conjunction with the associated ATM shaping rate. The
aggregate rate of the combination of three priority queues (Class of Service Queuing
with Strict Priority) associated with a particular ATM virtual circuit is controlled by
the SCR (sustained cell rate) configured for the VC. In this case, SCR is configured
equal to PCR (peak cell rate). Rate information is configurable in the atm-qos profile
for each virtual circuit. For details about configuring ATM QoS, see the Stinger ATM
Configuration Guide.

The IP2000 controller has two Ethernet interfaces, one 10/100 BASE-T interface for
management access to the unit via Telnet or SNMP, and one Gigabit Ethernet
interface for high-speed access to a local IP subnet. For information about configuring
the management interface, see the Getting Started Guide for your Stinger platform.

The Gigabit Ethernet MAC (GMAC) physical interface operates only in full-duplex
mode only for a full 1Gbps throughput. It supports auto-negotiation for advertising
its rate and duplex mode, but not for renegotiating it on the IEEE 802 LAN.

Stinger units with redundant IP2000 controllers can be configured to enable Gigabit
Ethernet port redundancy. With proper configuration, RFC 1483 (MPoA)
connections, VLAN connections, and MBONE interface functions can be maintained
across Gigabit Ethernet following a controller switchover.

2

Configuring the physical and logical interface

The system creates configuration profiles for both IP2000 Ethernet interfaces. For
each controller, interface 1 is always the 10/100 BASE-T management interface, and
interface 2 is the Gigabit Ethernet interface. For example:

admin> dir ethernet
18 07/11/2003 13:55:31 { shelf-1 first-control-module 1 }
24 07/11/2003 19:34:41 { shelf-1 first-control-module 2 }
18 07/11/2003 13:55:31 { shelf-1 second-control-module 1 }
24 07/11/2003 13:57:32 { shelf-1 second-control-module 2 }

admin> dir ip-interface
21 07/11/2003 13:55:31 { { any-shelf any-slot 0 } 0 }
31 07/11/2003 22:46:34 { { shelf-1 first-control-module 1 } 0 }
21 07/11/2003 13:57:01 { { shelf-1 first-control-module 2 } 0 }
21 07/11/2003 13:55:31 { { shelf-1 second-control-module 1 } 0 }
21 07/11/2003 13:57:01 { { shelf-1 second-control-module 2 } 0 }

Stinger® IP2000 Configuration Guide 2-1

Gigabit Ethernet Configuration

Configuring the physical and logical interface

Viewing ethernet profile settings

To configure the data-link functions of the Gigabit Ethernet interface, open the

ethernet profile. For example:
admin> read ethernet { 1 8 2 }
admin> list

[in ETHERNET/{ shelf-1 first-control-module 2 }]
interface-address* = { shelf-1 first-control-module 2 }
link-state-enabled = no
enabled = yes
ether-if-type = fiber
bridging-enabled = no
filter-name = ""
duplex-mode = full-duplex
pppoe-options = { no no }
bridging-options = { 0 no no }
media-speed-mbit = 1000mb
auto-negotiate = no

For details about each of the parameters shown above, see the Stinger Reference.
Following are some Gigabit Ethernet-specific notes about the profile contents:

Parameter Notes about Gigabit Ethernet settings

interface-address*

link-state-enabled

enabled

ether-if-type

bridging-enabled

filter-name

duplex-mode
pppoe-options

The profile index and interface-address value of the
profile for a Gigabit Ethernet interface always specifies
an interface number of 2. For example:

shelf-1 first-control-module 2

With the default value, the system discards packets and
does not choose an alternate route if the interface is
down. If you set this to yes, the system deletes routes to
the interface when the interface is unavailable, and
then restores the routes when the interface becomes
available again.

If you set this to no and write the profile, the interface is
unavailable.

This setting is read-only and specifies either fiber or
utp (CAT5 unshielded twisted pair).

Enable/disable LAN packet bridging on the interface.
Set this parameter to yes to enable bridging on the
Gigabit Ethernet port. This is required for VLAN
operations. See Chapter 3, “VLAN Configuration.”

Applies a data filter to the interface. See Chapter 10,
“Filter Configuration.”

This setting is read-only and specifies full-duplex mode.

Not used by the IP2000.

2-2 Stinger® IP2000 Configuration Guide

Parameter Notes about Gigabit Ethernet settings

bridging-options

media-speed-mbit
auto-negotiate

Not used by the IP2000. If you are configuring VLANs, you
set bridging options in the vlan-ethernet profile (not
in the ethernet profile). For details, see Chapter 3,
“VLAN Configuration.”

This setting is read-only and specifies 1Gbps.
Setting this parameter to yes does not cause the IP2000

to negotiate its duplex mode or speed, but it does cause
the system to advertise a full-duplex 1Gbps port , which
helps to ensure compatibility with remote Gigabit
Ethernet interfaces that support autonegotiation.

Modifying default ethernet settings

With the default settings, the Gigabit Ethernet interface is fully operational. The
following commands enable autonegotiation, to help ensure compatibility with other
Gigabit Ethernet interfaces that can negotiate between full-duplex and half-duplex
operations. (The IP2000 Gigabit Ethernet always operates in full-duplex mode.)

admin> read ethernet { 1 8 2 }
admin> set auto-negotiate = yes
admin> write -f

Gigabit Ethernet Configuration

Verifying the Gigabit Ethernet interface setup

Assigning an IP address in the ip-interface profile

For details about the ip-interface profile, and about enabling dynamic routing or
configuring static routes to enable the system to communicate beyond its own
subnet, see “Configuring ip-interface profiles for Ethernet ports” on page 4-6. The
following commands provide the minimal configuration of an IP address for the
Gigabit Ethernet interface:

admin> read ip-interface { { 1 8 2 } 0 }
admin> set ip-address = 10.99.99.101/24
admin> write -f

Verifying the Gigabit Ethernet interface setup

After you assign an IP address, you can verify that the Gigabit Ethernet interface is
able to handle IP traffic by checking some command output. For details about the
netstat and gmac commands, see the Stinger Reference.

You can also use the debug-level ifmgr -d command to verify that the Gigabit
Ethernet interface is active. This is described in Appendix A, “IP2000 Diagnostics.”

Checking the routing table

The following command output verifies that the routing table has an entry for the
Gigabit Ethernet interface (IP address 100.1.1.3/32):

Verifying the network processor setup for the interface

The network processor on the IP2000 creates a connection entry for the Gigabit
Ethernet interface when the interface becomes operational. You can force the
network processor to create a connection entry for the Gigabit Ethernet interface by
using the following command:

admin> gmac -n
NP setup for gmac done.

Verifying the SAR setup for the interface

The Stinger Segmentation and Reassembly (SAR) creates an ATM connection entry
for the Gigabit Ethernet interface. You can force the SAR setup by using the following
command:

admin> gmac -s
GMAC: SAR conn. open with vpi = 0, vci = 200

Verifying IP packet transfer on the interface

The following command clears statistics gathered on the Gigabit Ethernet interface:

admin> gmac -d -c

The next command pings a host on the same subnet as the Gigabit Ethernet interface:

admin> ping 100.1.1.10

Gigabit Ethernet port redundancy

With the proper configuration, systems with redundant controllers support Gigabit
Ethernet redundancy, which enables the system to maintain RFC 1483 (MPoA)

Stinger® IP2000 Configuration Guide 2-5

Gigabit Ethernet Configuration

Gigabit Ethernet port redundancy

connections, VLAN connections, and LAN MBONE interface functions across a
controller switchover.

Note A soft IP interface configuration is required for Gigabit Ethernet redundancy of

RFC 1483 connections and a LAN MBONE interface.

Configuring a soft IP interface for Gigabit Ethernet redundancy

The soft IP interface is an internal interface that is not associated with a specific
physical port, but that can be accessed through the Ethernet interface of whichever
controller is primary. For background information, see “Defining a soft interface for
increased accessibility” on page 4-8.

The system creates one soft interface profile by default. For example:

admin> dir ip-interface

35 07/10/2003 11:26:10 { { any-shelf any-slot 0 } 0 }
35 07/10/2003 11:26:10 { { shelf-1 first-control-module 1 } 0 }
38 07/10/2003 11:26:11 { { shelf-1 first-control-module 2 } 0 }
35 07/10/2003 11:26:10 { { shelf-1 second-control-module 1 } 0 }
38 07/10/2003 11:26:11 { { shelf-1 second-control-module 2 } 0 }

You can use the default soft IP interface { {0 0 0 } 0 } for Gigabit Ethernet
redundancy. However, if you have already used the default profile for the soft IP
address of the 10/100M base Ethernet management ports, you can create another
soft IP interface using a profile index of { { 0 0 0 } x }, as long as the IP address in
that profile is on the same subnet as the Gigabit Ethernet ports.

Note The system associates its Ethernet interfaces with a particular soft address

based on the subnet assignment. The IP interface address of the Gigabit Ethernet
ports on the primary and secondary controllers and the soft IP interface address must
be on the same subnet.

Configuring Gigabit Ethernet redundancy for RFC 1483 connections

Figure 2-1 shows a Stinger with redundant IP2000 controllers. The Gigabit Ethernet
port in slot 8 ({ { 1 8 2 } 0 }), the Gigabit Ethernet port in slot 9 ({ { 1 9 2 } 0 }),
and the soft IP interface ({ { 0 0 0 } 1 }), all have IP address assignments on the
same subnet. In addition, the external router has a routing table entry that specifies
the soft IP interface address as the gateway to the CPE router destination.
