Basic System Services
• CSCdx55178
Symptoms: Difficulties may occur when you attempt to remotely log in to a Cisco router that
supports ATM. After you have established a virtual terminal connection to the system, the following
user access verification sequence may be displayed, and the connection terminated:
Password:

Password:
% Bad passwords
Conditions: This symptom is observed on a Cisco router that support ATM when an interactive ATM
ping is terminated abnormally.
Workaround: Instead of using an interactive ATM ping, enter the ping atm interface atm interface
vpi vci [seg-loopback | end-loopback] [repeat [timeout]] privileged EXEC command.
• CSCea21328
Symptoms: After a Versatile Interface Processor (VIP) has reloaded, there does not seem to be a
crashinfo file because the crashinfo file is not closed; therefore, it is not visible or accessible. If the
same VIP reloads again, both the first and second crashinfo files are accessible.
Conditions: This symptom is observed on a Cisco 7500 series that is running Cisco IOS
Release 12.2(6f). The symptom may also occur in other releases.
Workaround: There is no workaround.
• CSCec69536
Symptoms: When you reload a Cisco 7500 series router with a new Cisco IOS software image, the
router may reload unexpectedly during the bootup process and generate an “Imprecise cache parity
error” message.
Conditions: This symptom is observed on a Cisco 7500 series that is configured with a Route Switch
Processor 8 (RSP8) and that runs Cisco IOS Release 12.0 S or Release 12.2(18)S when you reload
the router with an image of Cisco IOS Release 12.3 T.
Workaround: Do not reload the router. Rather, power-cycle the router to properly load the image of
Cisco IOS Release 12.3 T.
• CSCed33110
Symptoms: A VIP crash may cause memory exhaustion on an RSP, which in turn may cause the RSP
to crash.
Conditions: This symptom is observed more frequently on routers with a high IDB count.
Workaround: There is no workaround.
• CSCed75238
Symptoms: A serial interface on a Cisco 7500 series may stop transmitting traffic and may report
the following VIP crashes:
