Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S1
• CSCee28481
Symptoms: After working fine for sometime, a 4-port OC-12 ATM line card stops forwarding
unicast packets to the RP, and none of the unicast traffic that is sourced from or destined to the RP
via the 4-port OC-12 ATM line card goes through. Unicast traffic to the 4-port OC-12 ATM line card
interfaces fails too.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(21)ST7 when MPLS is enabled on the line card. IP traffic and IS-IS traffic that pass
through the router are not affected. To recover the line card, reset the line card.
Workaround: There is no workaround.
• CSCee28754
Symptoms: GE interfaces on an EPA-GE/FE-BBRD line card may drop tag packets.
Conditions: The problem is reported on a Cisco 12000 series running Cisco IOS Release 12.0(23)S5
only when you perform an OIR of an EPA-GE/FE-BBRD to install or remove additional
EPA-3GE-SX/LH line cards.
Workaround: Perform a second OIR of the line card.
• CSCee29196
Symptoms: When a Cisco 10000 series does not have a specific route for both end points of a voice
connection, the Cisco 10000 series duplicates one-way audio only for the specific route that
populates its routing table, not for the end point that uses the default route from the routing table.
Conditions: This symptom is observed on a Cisco 10000 series that is runs Cisco IOS
Release 12.0(25)S3 and that is configured with a PRE-1.
Workaround: There is no workaround.
• CSCee30089
Symptoms: If a multilink interface loses members of the bundle, or if you enter the shutdown
command followed by the no shutdown command on a multilink interface, or if the router reloads,
the bandwidth that is allocated for non-real time classes can be allocated incorrectly. The sum of the
bandwidth that is allocated for non-real time classes and the bandwidth that is specified by the police
bps command for real time traffic may exceed the actual bandwidth of a multilink interface.
Conditions: This symptom is observed on a Cisco 10000 series running Cisco IOS
Release 12.0(27)S1 that has the service-policy out command enabled on a multilink interface. The
service policy consists of a real-time class and several classes with reserved bandwidth The
real-time class is configured with the priority command and the police bps command. Other classes
are configured with the bandwidth bandwidth-kbps command.
The bandwidth that is allocated for non-priority traffic should take into account the bandwidth that
is reserved by the police bps command for the real-time class.
Workaround: Remove and reapply the service-policy out command to the multilink interface.
• CSCee30116
Symptoms: CNS config notify events may stop coming.
Conditions: This symptom is observed when the cns config notify diff command is enabled and
when other CNS configuration agents are configured.
Workaround: Enter the no cns config notify command followed by the cns config notify diff
command.
