Configuring the Wideband SIP

---

This chapter provides information about configuring the Wideband SIPs on the Cisco uBR10012 router. It includes the following sections:

•Configuration Tasks

•Resetting a SIP

For information about managing your system images and configuration files, refer to the Cisco IOS Configuration Fundamentals and Network Management Configuration Guide, Release 12.3 and the Cisco IOS Configuration Fundamentals and Network Management Command Reference, Release 12.3.

For more information about the commands used in this chapter, refer to this documentation in the order shown:

1. Chapter 11, "SIP and SPA Commands," in this guide

2. Cisco Broadband Cable Command Reference Guide

Also refer to the related Cisco IOS Release 12.3 command reference and master index publications. For more information about accessing these publications, see the "Related Documentation" section on page 9.

Configuration Tasks

This section describes how to configure the Wideband SIP and includes information about verifying the configuration. It includes the following topics:

•Identifying the Location of Wideband SIPs and SPAs

•Required Configuration Tasks

•Optional Configuration Tasks

Identifying the Location of Wideband SIPs and SPAs

This section describes how to specify the physical locations of a Wideband SIP and Wideband SPA on the Cisco uBR10012 router within the Cisco IOS command-line interface (CLI) to configure or monitor those devices.

Specifying the Location for a Wideband SIP

In Cisco IOS commands, the Wideband SIP is designated by its location in the Cisco uBR10012 chassis. The location is in the form:

slot/subslot

On the Cisco uBR10012 router, the Wideband SIP occupies two full-height line card slots: either slots 1/0 and 2/0, or slots 3/0 and 4/0. On the Cisco IOS CLI, the location of the Wideband SIP is specified as follows:

•If the Wideband SIP occupies slots 1/0 and 2/0, the location for the Cisco IOS CLI is specified as slot/subslot 1/0.

•If the Wideband SIP occupies slots 3/0 and 4/0, the location for the Cisco IOS CLI is specified as slot/subslot 3/0.

---

Note When the Cisco uBR10012 router is used as a wideband CMTS, half-height Gigabit Ethernet (HHGE) line cards and the associated slot splitters must be installed in slot 3 or slot 4. Therefore, the Wideband SIP is installed in slots 1/0 and 2/0.

Figure 4-1 shows the slot numbering on the Cisco uBR10012 router.

Figure 4-1 Cisco uBR10012 Router Slot Numbering

Some Cisco IOS commands, such as show diag, allow you to display information about a Wideband SIP. These commands require you to specify the chassis location for the SIP that you want information about. For example, to display status and information about the Wideband SIP installed in slot/subslot 1/0, enter the following command:

Router# show diag 1/0

For information about Cisco IOS commands that can be used for a SIP, see Chapter 11, "SIP and SPA Commands."

Specifying the Location for a Wideband SPA

In Cisco IOS commands, the Wideband SPA is designated by its location in the Cisco uBR10012 chassis and in the Wideband SIP as follows:

slot/subslot/bay

A bay number identifies the location of each Wideband SPA in the Wideband SIP. Bay numbers in the Wideband SIP are shown in Figure 4-2. The Wideband SPA can be installed in bay 0 or bay 1. Therefore, on the Cisco uBR10012 router when the Wideband SIP is installed in slot/subslot 1/0, the slot/subslot/bay locations for the two Wideband SPAs are 1/0/0 and 1/0/1.

Figure 4-2 Wideband SPA Bay Numbering in Wideband SIP

Each Wideband SPA has two Gigabit Ethernet ports: one active and one redundant. The active port is used to send downstream traffic to one or more edge QAM devices. The individual Gigabit Ethernet ports on the Wideband SPA are not specified on the Cisco IOS CLI.

Some Cisco IOS commands, such as show diag, allow you to display information about a Wideband SPA. These commands require you to specify the chassis location for the SPA that you want information about. For example, to display status and information about the Wideband SPA installed in slot/subslot/bay 1/0/1, enter the following command:

Router# show diag 1/0/1

For information about Cisco IOS commands that can be used for a SPA, see Chapter 11, "SIP and SPA Commands."

Required Configuration Tasks

There are no required configuration tasks for the Wideband SIP.

Optional Configuration Tasks

Preprovisioning is an optional configuration task for the Wideband SIP and Wideband SPA. Preprovisioning on the Cisco uBR10012 router allows you to configure the Wideband SIP and Wideband SPA without their being physically present.

Two steps are required to preprovision the Wideband SIP and Wideband SPA:

1. The Wideband SIP is preprovisioned with the card command and 2jacket-1 as the card type:

card slot/subslot 2jacket-1

For example:

Router# configure terminal 

Router(config)# card 1/0 2jacket-1 

2. The Wideband SPA is preprovisioned with the card command and 24rfchannel-spa-1 as the card type:

card slot/subslot/bay 24rfchannel-spa-1

For example:

Router# configure terminal 

Router(config)# card 1/0/0 24rfchannel-spa-1 

The preceding card command creates 12 wideband channels per Wideband SPA.

Resetting a SIP

To reset a Wideband SIP, use the following command in privileged EXEC configuration mode:

Command	Purpose
Router# hw-module subslot slot/subslot reset	Turns power off and on to the SIP in the specified slot and subslot, where: •slot—Specifies the slot where the Wideband SIP resides. On the Cisco uBR10012 router, slots 1 and 3 can be used for the Wideband SIP. •subslot—Specifies the subslot where the Wideband SIP resides. On the Cisco uBR10012 router, subslot 0 is always specified.

Resetting a Wideband SIP is not usually done but may sometimes be useful when troubleshooting a failed SIP.
