Caveats
Resolved Caveats—Cisco IOS Release 12.0(30)S
CSCin79899
Symptoms: When error recovery is performed on a 3-port Gigabit Ethernet (GE) line card that has
port 0 in the shutdown state, the 3-port GE line card stop passing traffic on all ports.
Conditions: This symptom is observed on a Cisco 12410 that runs Cisco IOS Release 12.0(23)S or
a later release and that is configured with an Engine 2 3-port line card.
Workaround: Reload the 3-port GE line card and leave port 0 in the up/down state.
CSCin80221
Symptoms: A Cisco router crashes when you enter the fsck command for an ATA flash disk.
Conditions: This symptom is observed when the boot sector of the ATA flash disk is corrupted and
when the router runs a release that is listed in the “First Fixed-in Version” field at
http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCed58384. Cisco IOS
software releases that are not listed in the “First Fixed-in Version” field at this location are not
affected.
Workaround: Format the disk.
CSCin82862
Symptoms: Multicast traffic is not switched from a multilink interface on a Cisco 7500 series that
is configured for distributed multilink PPP (MLP).
Conditions: This symptom is observed when the router is reloaded or when the multilink interface
flaps.
Workaround: Enter the clear ip mds linecard * command on the Route/Switch Processor (RSP).
CSCuk49494
Symptoms: An SSO during an MTU change can create FIA buffer inconsistencies between line
cards.
Conditions: This symptom is observed on a Cisco 12000 series.
Workaround: Reapply the MTU change on the new active RP.
CSCuk51177
Symptoms: You may not be able to make a Telnet connection to a Cisco IOS platform.
Conditions: This symptom is observed when the CNS Exec Agent is used to remotely issue an
interactive CLI command.
Workaround: There is no workaround.
CSCuk51269
Symptoms: Multicast packets such as HSRP and OSPF are not received on a port-channel interface.
Conditions: This symptom is observed when a port-channel interface is configured on a
Cisco router, when you reload the router, and when the first member is added to the port-channel
interface by entering the no shutdown interface configuration command on physical interface.
Workaround: Enter the do shutdown interface configuration command followed by the no
shutdown interface configuration command on the port-channel interface.
CSCuk52952
Symptoms: An Engine 3 ATM line card may continuously crash.
Conditions: This symptom is observed on a Cisco 12000 series that runs an interim release for
Cisco IOS Release 12.0(30)S after you configure IP QoS on an ATM interface of the line card. Note,
however, that this caveat is resolved in Release 12.0(30)S.
