Caveats

For more information on caveats in Cisco IOS Release 12.1 T, see the Caveats for Cisco IOS

Release 12.1 T document. All caveats in Cisco IOS Release 12.1 are also in Cisco IOS Release 12.1 T.

For information on caveats in Cisco IOS Release 12.1, see Caveats for Cisco IOS Release 12.1. These

documents list severity 1 and 2 caveats and only selected severity 3 caveats, and are located on CCO and

the Documentation CD-ROM.

Note If you have an account with CCO, you can use Bug Navigator II to find caveats of any

severity for any release. To reach Bug Navigator II, go to CCO and press Login. Then go

to Software Center: Cisco IOS Software: Cisco Bugtool Navigator II. Another option

is to go to http://www.cisco.com/support/bugtools (you must have an account on CCO to

Open Caveats—Release 12.1(5)T

All the caveats listed in this section are open in Release 12.1(5)T:

• CSCdp03592

This caveat affects the Cisco uBR924 router when it is configured as an H.323 gateway using the

following cable interface configuration commands:

–

h323-gateway voip interface

–

h323-gateway voip id gklocal ipaddr x.x.x.x 1719

–

h323-gateway voip h323-id [email protected]

When the Cisco uBR924 router reboots, this configuration will fail if these commands are executed

before the cable interface acquires a valid IP address from the DHCP server. In this situation, the

h323-gateway commands will be ignored, and voice calls that use that gateway will fail.

The workaround is to either reenter the gateway commands manually or to reload the entire

configuration using the copy start-config running-config command.

• CSCdm38753

The Cisco uBR924 router, when running the NAT and firewall features, crashes if establishing

roughly 150 Telnet sessions (using the solaris_telnet client). The workaround is to avoid creating

that many Telnet sessions.

• CSCdm75295

The Cisco uBR924 Cable Access Router can stop responding to CMTS requests when upstreams

are configured with different minislot sizes. The workaround is to configure the upstreams on the

CMTS with the same minislot size.

• CSCdp03177

When running Cisco IOS Release 11.3(11)NA, the Cisco uBR924 Cable Access Router does not

come up when all four downstreams are combined through the upconverter and all of the upstreams

of the four cards are combined. When the Cisco uBR924 router is instructed to go to a different

downstream, it obtains the correct IP address for the new downstream, but fails to update the default

gateway according to the DHCP reply; it subsequently fails to obtain the time-of-day (TOD) or to

download the DOCSIS configuration file. The default gateway address must be corrected manually

before the router succeeds in obtaining the configuration file and in getting the current time-of-day.
