Resolved Caveats—Cisco IOS Release 12.0(3)
• CSCdk46621
When a Cisco router interface is configured as a DCE, it does not track the correct control lead
coming from the DTE. The interface stays up and up when the DTR is low. There is no workaround.
• CSCdk50924
If two users on different tty connections simultaneously attempt to issue commands that access
NVRAM (for example, show startup-config), the router might reload. There is no workaround.
• CSCdk55631
After you load a startup configuration by issuing the copy tftp startup-config command on a Cisco
3620 router, the NVRAM becomes unreadable on the next reload. During the boot sequence the
following messages can be seen:
ERROR in NVRAM sizing. NVRAM could be bad! Hardware indicated 32768 bytes. Software
detected 0 bytes.
and
%C3600-3-BADNV: Detected invalid NVRAM size: -2056 bytes
This condition is extremely rare. To solve this problem, the customer will need to upgrade the ROM
Monitor boot ROM with a version that has this fix.
Workaround: Change each capital V in the configuration to a lower case v.
• CSCdk57202
When two peer subsystems (EECM-EECM or EECM-TDSM) communicate about a call, they
identify the call using their own call instance ID. A race condition occurs after you send a “SETUP”
message to the peer if you send a “RELEASE” message (or some other message) before the peer
has responded to the “SETUP” message. The peer does not get the call instance ID it expects and
therefore the message is lost. There is no workaround.
• CSCdk59099
AAA connection accounting works for a single connection on the router, but with multiple
connections start records are generated for all connections. Only the first disconnected call has a
stop record generated; subsequent closed connections do not. All records have the same
Acct-session-id. This problem exists in Cisco IOS Release 11.3(2.4)T or later. There is no
workaround.
• CSCdk62728
You cannot enter the aaa authorization exec tacacs configuration command. There is no
workaround.
• CSCdk63134
When you boot a Cisco router that has dual Route Switch Processors (RSPs) and multiple VIP
interfaces, the slave RSP might not change to the “Running” state, and might remain in the “Halted”
state. This condition results from a lack of buffers for IPC communication.
Workaround: Issue the slave reload configuration command once the system comes up.
• CSCdk66856
SNMP might be unable to get data on Run-from-Flash partitions. There is no workaround.
• CSCdk67339
When a Cisco 1600 series router is connected in synchronous mode using the “Easy IP” feature,
the WIC-1T synchronous/asynchronous might drop the PPP link. This condition is caused by
having ip address negotiated configured on the serial interface. When a static IP address is
configured, the problem does not occur. There is no workaround.
