Release Notes for Cisco uBR904 Cable Access Router for Cisco IOS Release 11.3 NA 15

Caveats for Release 11.3(1) through 11.3(10)NA.

• CSCdm28631

Under stressful conditions of (if the ESA is bringing up a large number of crypto sessions

simultaneously), it may either enter a race condition or get the crypto initiation messages wedged

in the input-q of the interface doing encryption.

• CSCdm31647

A customer reset a VIP card in slot 8 of one Cisco 7513, and the VIP crashed. When the VIP

came up, ISL trunking to slot 4 (PA-2FEISL-TX) started dropping large packets. However, small

packets go through the interface just ﬁne. Workaround is to reset the box.

• CSCdm33429

A Cisco AS5300 gets a bus error when it is under a heavy load caused by outgoing Modem calls.

Have tested with IOS 11.3(9)T and 11.3(8.5)T with same results.

Problem is reproducible within minutes.

• CSCdm33707

After the router is reloaded, ESA can not re-establish active crypto connection. The workaround

is to remove the crpto map, reload the the router again, and reapply the crypto map.

• CSCdm44057

When running virtual-proﬁle, theCisco 7500 keeps on resetting the cbus.

The ﬁrst message is "%RSP-3-RESTART: interface Serial4/0:1, output stuck" .

Then a little later, a reset occurs on the cbus. If debugging cbus, you can see the bus resetting.

This also causes all attached controllers to loose connectivity. The only way to access the box is

through the console port.

• CSCdm49454

Problem description: When cable ip-broadcast-echo is enabled, under certain timing

conditions, it may cause a buffer leak.

Workaround: Do not enable cable ip-broadcast-echo and cable ip-multicast-echo.

VINES

• CSCdk80167

Cisco 2500 series and Cisco 4000 series routers (68000-based routers) might reload a few

minutes after VINES Sequenced Routing Update Protocol (SRTP) is conﬁgured.

Workaround: Do not use VINES SRTP. If it is enabled, disable it by issuing the no vines

srtp-enabled command.

Wide-Area Networking

• CSCdk37517

DDR with dialer dtr does not reset DTR to a down state after an unsuccessful call attempt.

Unsuccessful in this case means that DD; therefore DCD does not come up.

This can be veriﬁed by viewing show dialer to ensure that the dialer state is idle; then enter show

interface serial x to check the state of DTR.

This problem does not seem to occur in Release 11.1.
