Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S
CSCeh97760
Symptoms: In the outputs of the show ip psa-cef and show ip cef commands for an Engine 2 ingress
line card, the “Local OutputQ (Unicast)” information may point to another and incorrect slot than
the slot that the global CEF table points to.
When this symptom occurs, packets that are destined for these specific IP address are dropped.
Conditions: This symptom is observed on a Cisco 12000 series when an Engine 2 line card is used
as an ingress line card for traffic that is directed to a default route.
Workaround: Enter the clear ip route 0.0.0.0 or clear ip route * command.
CSCeh97829
Symptoms: An RP may crash continuously when you reload all the line cards in a dual-RP router
that has the redundancy mode is set to SSO.
Conditions: This symptom is observed on a Cisco 12000 series that is configured with two GRPs or
two PRPs that are configured for SSO and occurs only when a 1-port channelized OC-48 ISE line
card, a 4-port channelized OC-12 ISE line card, or 16-port channelized OC-3 ISE line card is present
in the router.
Workaround: Set the redundancy mode to RPR or RPR+.
CSCei00027
Symptoms: On a channelized OC-48 ISE line card with APS configured, a “Signal Failure”
condition remains after the line card has been reloaded or after you enter the shutdown command
followed by the no shutdown command.
Conditions: This symptom is observed on a Cisco 12000 series and affects only a channelized OC-48
ISE line card with an APS configuration.
Workaround: There is no workaround.
CSCei01644
Symptoms: A 3-port Gigabit Ethernet (3GE-GBIC-SC) line card that is configured for Fast-Path
Multicast Forwarding may reset when receiving specific packets. However, it is not necessary that
the line card will crash all times. The resulting action on these packets could result in a simple drop
as well.
Conditions: This symptom is observed on a Cisco 12000 series when a packet with an IP destination
address from the reserved multicast range (224.0.0.xxx) and a TTL larger than 1 is received on the
3GE-GBIC-SC line card and when multicast hardware acceleration is enabled.
Normally, the TTL should be 1 if the destination address is part of the reserved multicast range.
Workaround: Enter the no hw-module slot slot-number ip multicast hw-accelerate source-table
size 16 offset 0 command.
CSCei03674
Symptoms: Class-default counters (that is, the total number of packets) do not increment.
Conditions: This symptom is observed on a Cisco router when a class map matches an OAM that is
applied to a policy.
Workaround: There is no workaround.
CSCei04350
Symptoms: MVPN PIM neighbors that are associated with both a 1-port channelized OC-48 ISE line
card and a 1-port channelized OC-12 (DS1) ISE line card bounce when you perform a
microcode-reload of a 1-port channelized OC-12 (DS1) ISE line card.
