Release Notes for Cisco uBR904 Cable Access Router for Cisco IOS Release 11.3 NA 13

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

Console message ﬂooding may occur when an XID3 loop occurs with APPN in the router. The

following messages are repeated for each iteration of the loop:

%APPN-3-logcsCS_XXXXIP11_LOGMSG_01: CS - Sending Alert to MS, sense_code = 83E0001,

proc_name = XXXXIP32, port_name = HMAC04, ls_name = @LS00289

%APPN-3-logcsCS_XXXXIP11_LOGMSG_03: CS - Associated outbound XID data in alert (length

>= 29): %APPN-3-Error:

Avoid console logging.

• CSCdm49573

The router crashes with bus error when executing a show dlsw circuit command if there is a

circuit with a local rif of 18 bytes.

This is a regression introduced by CSCdk83294.

• CSCdm50361

DLSw Lite peers leak CLS connect request buffers. If possible, try using a different peer type.

This patch frees an outstanding connect request if additional requests are received while the ﬁrst

request is still pending.

Interfaces and Bridging

• CSCdk10376

SYMPTOM: Crash in frf9_preComp()

This ondition most frequently occurs during times when router trafﬁc is heavy, which causes

memory usage to increase and a possible low-memory condition to occur.

WORKAROUND: Disable compression or use a different type.

Since this problem is aggravated by a low-memory condition, tuning the memory can prevent this

condition from occurring, but there are no guarantees.

• CSCdm41644

This is caused by an over-write issue in bss area with FDDI modules equipped which has

potential to cause serious problem such as crash in 12.0T.

• CSCdm46735

A PA-4R-DTR port may reset under the following circumstances:

1) A high rate of trafﬁc is traversing the port (200 pps or better) .

2) The PA-4R-DTR port is the active monitor of the physical ring.

3) An event on the ring forces the active monitor to purge the ring.

When this problem occurs, the PA-4R-DTR port resets, and the ring experiences a beacon.

Workaround: Make sure the DTR port is not the active monitor on the ring. This can be done by

ensuring that the mac-address of the DTR card is not the highest mac-address on the physical

ring.
