Resolved Caveats—Cisco IOS Release 12.0(2)
Basic System Services
• CSCdj78490
Cisco 1003 routers sharing S bus frequently have problems. Even though diagnostics show that the
router is responding to IDCKREQ from the ISDN switch, these responses are lost in collisions and
never seen by the ISDN switch.
• CSCdk08376
LANE clients might drop with the message “SNMP CPUHOG processing GetNext IfEntry” on the
ATM subinterfaces. In some cases, numerous subinterfaces were defined, which were not numbered
sequentially. A partial workaround is to issue the command no snmp-server sparse-table, which
lessens the frequency of occurrence.
• CSCdk09806
When configuring traffic-shape groups under interfaces, the second traffic-shape group does not
show in the running-config or startup-config if options are not added to the command as the first
statement.
• CSCdk11908
A Cisco 1005 router might report the following message repeatedly:
%ETHERNET-1-TXERR: Ethernet0: Fatal transmit error. Restarting... %QUICC-5-COLL: Unit
0, excessive collisions. Retry limit 15 exceeded
• CSCdk24065
A router might fail and display this bus error:
System was restarted by bus error at PC 0x6013425C, address 0xD0D0D6D
• CSCdk27388
There might be a problem on the VIP with regard to fragmentation of packets that can cause the
DMA engine to stall (and cause the VIP to fail). The message “DMA receive error” might be
displayed. There is no workaround.
• CSCdk33632
Under noisy line conditions a giant packet followed by a runt packet on a serial line causes a
Cisco 2600 series router to fail.
• CSCdk36156
A router becomes unresponsive when a query router history is attempted and the history table is
empty.
• CSCdk38758
With RSP HSA, issuing the command write memory might not correctly update the ROM monitor
boot variables on the slave processor.
Workaround: Verify that the BOOT variables have been correctly written by issuing the show
bootvar command on the master after every write memory command, and reissuing the write
memory command as many times as necessary.
• CSCdk39738
After a user dials in to a Cisco AS5200 access server and is passed to the TACACS+ server, and is
authenticated, the access list that is passed back to the router by the TACACS+ server is not applied
to the asynchronous interface by the router. There is no workaround.
