Release Notes for Cisco uBR924 Cable Access Router for Cisco IOS Release 12.1(5)T
OL-0385-04 Rev. B0 (2/2001)
New and Changed Information
Note The h323-gateway voip bind command should be used only when the Cisco uBR924
Cable Access Router is operating in routing mode. This command has no effect when the
router is operating in DOCSIS bridging mode.
This feature was tracked as caveat CSCdp11931, and is introduced in Cisco IOS Release 12.1(2)T.
RFC 2233 Support
Cisco IOS Release 12.1(2)T updates the IF-MIB MIB with support for RFC 2233, which makes the
previous RFC 1573 obsolete. This change adds the “ifCounterDiscontinuityTime” attribute and changes
the “ifTableLastChange attribute”.
In addition, this feature adds support for RFC 2233-compliant link-up and link-down traps. By default,
link-up and link-down traps are implemented as given in the CISCO-IF-CAPABILITY.my MIB. To
generate link-up and link-down traps as defined by RFC 2233, use the snmp-server trap link ietf
global configuration command.
This feature was tracked as caveats CSCdp41317 and CSCdp55546, and is introduced in Cisco IOS
Release 12.1(2)T.
No New Hardware Features in Release 12.1(1)T
Cisco IOS Release 12.1(1)T does not contain any new hardware features for the Cisco uBR924 Cable
Access Router.
New Software Features in Release 12.1(1)T
The following new software features are supported by the Cisco uBR924 Cable Access Router for
Cisco IOS Release 12.1(1)T. For more information on these features, see the documentation listed in
the “Related Documentation” section on page 34.
Cable Monitor Web Diagnostics Tool
The Cable Monitor is a web-based diagnostic tool to display the current status and configuration of the
Cisco uBR924 router. The Cable Monitor can also be used when the cable network is down, providing
an easy way for subscribers to provide necessary information to service technicians and
troubleshooters.
The Cable Monitor is introduced in Cisco IOS Release 12.1(1)T.
Cisco Cable Clock Card Support
When using Cisco IOS Release 12.1(1)T or greater, the Cisco uBR924 Cable Access Router
automatically supports the Cisco Cable Clock Card feature for voice traffic when the CMTS is a
Cisco uBR7200 series universal broadband router with the Cisco Cable Clock Card feature. This
feature can enhance reliability in a voice network and reduce delay and jitter in the voice traffic.
