OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S4
• CSCee69887
Symptoms: A dual SRP ring fails to become active completely due to an is-type mismatch. The
output of the show clns neighbors command indicates that a certain system interface remains in the
“Init” state indefinitely, although the output of the show ip interface brief command shows that this
interface is up.
Conditions: This symptom is observed when a dual SRP ring is configured on three routers that run
Cisco IOS Release 12.2S. The symptom may also occur in other releases.
Workaround: There is no workaround.
• CSCee70591
Symptoms: A Cisco 7500 series T3 port adapter (PA-2T3+) may not provide a two-second delay
before bringing down the T3 controller.
Conditions: This symptom is observed when an alarm as defined in the ANSI T1.231 specification
occurs.
Workaround: There is no workaround.
• CSCee72906
Symptoms: A VIP may crash when you remove a service policy from a multilink interface or when
a member link is removed from the multilink interface while heavy traffic is being processed.
Conditions: This symptom is observed on a Cisco 7500 series that has an RSP and that is configured
for dLFI over a leased line, MLP, and QoS.
Workaround: There is no workaround.
• CSCee73410
Symptoms: When you enter the redundancy force-switchover command, IPC messages and
tracebacks may be generated on an Engine 2 3-port GE line card.
Conditions: The symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(28)S or an earlier release and that has dual GRPs or dual PRPs.
Workaround: There is no workaround.
• CSCee79728
Symptoms: A Cisco 7200 series that operates in the process switching path may crash with a bus
error exception.
Conditions: This symptom is observed on a Cisco 7200 series that runs Cisco IOS
Release 12.2(13b)M2 and that is configured with a serial or POS port adapter. The symptom may
also occur in other releases.
Workaround: Enter the ip route cache command for all interfaces.
• CSCee83781
Symptoms: A Cisco router may reload when you enter the show ipv6 mfib verbose command for a
large MFIB.
Conditions: This symptom is observed on a Cisco 12000 series that is configured for multicast.
Workaround: There is no workaround.
• CSCee84732
Symptoms: The CPU utilization of a router that is configured for Multiprotocol Label Switching
(MPLS) may temporarily increase to 80 or 90 percent when a peer router is reloaded or when an
interface with a large number of numbered subinterfaces is administratively enabled.
