Release History

 

Cisco IOS Release	Modification
Release 12.3(21)BC	Support for the following SPAs was introduced for the Cisco Wideband SIP on the uBR10012 router: •Cisco 1-Gbps Wideband SPA (referred to in this document as the Cisco Wideband SPA or Wideband SPA)

Supported Features

The Cisco uBR10012 router with a Wideband SIP can support up to two Wideband SPAs. The following is a list of some of the significant hardware and software features supported by each Wideband SPA:

•Up to 12 channel-bonded wideband channels per Wideband SPA

•Up to 24 RF channels (Annex B) or 18 RF channels (Annex A) per Wideband SPA

•Cisco Wideband Cable for DOCSIS Network support

•Two Gigabit Ethernet ports (one of which is redundant) for link to edge QAM devices

•Traditional DOCSIS 1.X/2.0 upstream channels

•64 QAM and 256 QAM support

•6 MHz and 8 MHz support

•BPI (Baseline Privacy Interface)/BPI+ encryption

•Single-wide, half-height SPA form factor

•Small form-factor pluggable (SFP) modules that plug into the Gigabit Ethernet ports

•SFP module support for:

–SX, LX/LH, and ZX optical fiber (1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX)

•Cisco IOS command set for wideband-channel configuration, provisioning, and maintenance

•Cisco IOS command set for wideband channel hardware monitoring, troubleshooting, and debugging

•MIB support

•Online insertion and removal (OIR)

Restrictions

The following restrictions apply to the Wideband SPA for Cisco IOS Releases 12.3(21)BC and 12.3(21a)BC3:

•Wideband services are data-only.

•Only best effort flows are configurable on wideband channels.

•No dynamic services are configurable on wideband channels.

•Traffic from different Wideband SPAs cannot be mixed on the same QAM port.

•Scientific Atlanta DPC2505 and EPC2505 wideband cable modems support multicast traffic on the primary downstream channel only. These modems do not support multicast traffic on wideband downstream channels.

Supported MIBs

The following MIBs are supported in Cisco IOS Release 12.3(21)BC and later for the Cisco uBR10012 router and the Wideband SPA:

•ENTITY-MIB

•CISCO-CABLE-WIDEBAND-MIB

•IF-MIB

•CISCO-VENDORTYPE-OID-MIB

Displaying Wideband SPA Information

To verify the SPA type that is installed in your Cisco uBR10012 router, you can use the show diag command. Table 7-1 shows the card type that appears in the show diag command output for the Wideband SPA.

---

Tip With Cisco IOS commands, the Wideband SPA Gigabit Ethernet ports are not standard user-configurable interfaces and do not appear in the output of the show interfaces command.

You can get information on the Wideband SPA Gigabit Ethernet ports using the show controllers wideband-cable command with the ge_phy keyword. For information on this command, see show controllers modular-cable, page 11-41.

Table 7-1 SPA Card Descriptions in show Commands

SPA	Description in show diag command
Wideband SPA	24rfchannel-spa-1

The 12 wideband channels on each Wideband SPA are similar to cable interfaces and appear in the output of commands such as show interfaces and show interface wideband-cable.

The show hw-module bay command displays a variety of information about the RF channels and wideband channels on a Wideband SPA. For information on this command, see show hw-module bay, page 11-44.
