Resolved Caveats—Cisco IOS Release 12.0(32)S
• CSCei08823
Symptoms: When a ToFab FCRAM single-bit error (SBE) occurs on an Engine 5 line card, the
following error message is generated, and the line card resets:
Tofab BMA has lost a command
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(31)S and occurs only on an Engine 5 line card.
Workaround: There is no workaround.
• CSCei09755
Symptoms: When you remove a multilink bundle by entering the no ppp multilink command under
a serial link configuration, a serial link that is configured in the multilink bundle remains in the “line
protocol down” state and does not recover.
Conditions: This symptom is observed on a Cisco 7600 series that is configured with a SIP1 line
card in which a SPA-CT3 is installed and on a Cisco 12000 series that is configured with a SIP-400
or SIP-600 in which a SPA-CT3 is installed.
Workaround: Reload the SPA by entering the hw-module subslot slot subslot reload command.
• CSCei09876
Symptoms: A router that is configured for MPLS VPN cannot accept a Route Distinguisher with the
value 0:0.
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.0S or
Release 12.4 and that integrates the fix for CSCeh12594. A list of the affected releases can be found
at http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCeh12594. Cisco IOS
software releases that are not listed in the “First Fixed-in Version” field at this location are not
affected.

workaround.
