Resolved Caveats—Cisco IOS Release 12.0(28)S1
• CSCed02844
Symptoms: IPv6 adjacencies may appear as incomplete, and connectivity may be broken. This
situation occurs at random times and is not associated with any event in particular. IPv4 adjacencies
may appear as incomplete but recover within a minute.
Conditions: This symptom is observed on a Cisco IOS-based router when you enter the clear
adjacency command.
Workaround: To restore the correct state of the adjacency, enter the shutdown command followed
by the no shutdown command on the affected interface.
• CSCed08168
Symptoms: No SNMP linkup or linkdown trap is generated for a 1CHOC12/4CHSTM1 SONET
layer when a controller goes up and down.
Conditions: This symptom is observed when monitoring a SNMP linkup or linkdown trap for a
1CHOC12/4CHSTM1 SONET layer.
Workaround: Monitor the controller status using the show controller sonet command.
• CSCed16318
Symptoms: When changing the MTU on an Engine 2 3-port 1GE line card, the line card may reload.
Conditions: This symptom is observed on a Cisco 12416 router that is running the gsr-p-mz image
of Cisco IOS Release 12.0(26)S.
Workaround: Ensure there is no traffic going through the Engine 2 3-port 1GE line card when
attempting to change the MTU.
• CSCed22303
Symptoms: The interface on an Engine 3 line card is stuck after hours of testing. When incoming
packets are ignored, PPP does not go up.
Conditions: This symptom is observed on Cisco 12000 series router after hours of testing with an
attenuator.
Workaround: Enter the shutdown command followed by the no shutdown command on the affected
interface.
• CSCed35964
Symptoms: Interoperating problems may occur with a particular third-party vendor 48 MB flash
card, and a router may not be able to read the flash card with “bad majic” and “-13 open file” error
messages.
Conditions: This symptom is observed in the following two scenarios:
– Scenario 1: If the flash card is formatted on one router and then inserted in another router, the
boot image and Cisco IOS image can be read from the flash card until you reload the router.
After the router is reloaded, “bad majic” and “-13 open file” error messages occur.
– Scenario 2: When you remove the first large file from the flash card (irrespective of its position
on the flash card and irrespective of whether or not the file is a Cisco IOS file) and you reload
the router, “bad majic” and “- 13 open file” error messages occur, and the router may enter a
continuous loop. The symptom occurs with the removal of a file that is 12 MB or 14 MB but
does not occur with the removal of a file of 4 MB.
Workaround: There is no workaround.
