Resolved Caveats—Cisco IOS Release 12.0(28)S
• CSCee12772
Symptoms: On certain platforms (in particular but not limited to a Cisco 800 series), the CNS agents
code that captures output for later transmission can crash.
Conditions: This symptom is observed on a router that has configuration and EXEC agents and CNS
agents that execute CLI commands when you send an XML file to direct these agents to execute a
CLI command and return the output (if there is any output).
Workaround: Telnet into the router (not through the console) and exit. This may need to be done
multiple times.
• CSCee13315
Symptoms: A router crashes when you attach a policy map to an interface.
Conditions: This symptom is observed when you remove random detect from a class, remove a class
that has random detect configured, or remove a policy map with a class that has random detect
configured.
Workaround: There is no workaround.
• CSCee16581
Symptoms: Traffic is sent using the “net ctrl” queue on the egress interface.
Conditions: This problem occurs on a Cisco 10720 router when IPv6 high-priority traffic (110 or
111 in the first 3 bits of the IPv6 traffic class) is forwarded.
Workaround: There is no workaround.
• CSCee16950
Symptoms: IPv6 traffic forwarding on an Engine 2 DPT line card is performed by the CPU of the
line card; IS-IS, OSPFv2 or OSPFv3 adjacencies, or BGP neighbourships across any of the
interfaces of the Engine 2 DPT line card may fail.
Conditions: This symptom is observed when oversubscribing the CPU of the Engine 2 DPT line card
in terms of its maximum IPv6 packet-per-second forwarding rate, which is about 100 Kpps.
Workaround: There is no workaround. The symptom does not occur for POS and GE Engine 2 line
cards.
• CSCee18844
Symptoms: Traffic forwarding problems may occur when sending MVPN traffic from multiple
sources to the same group.
Conditions: This symptom is observed on a Cisco 12000 series that functions as an MVPN
decapsulation PE router with an Engine 3 line card that forwards multicast packets on an VRF
interface.
Workaround: To ensure that no collisions occur on the VRF interface, configure hardware multicast
on the Engine 3 line card by entering the hw-module slot number ip multicast hw-accelerate
source-table size x offset y command.
• CSCee19222
Symptoms: An MLP bundle configured between a Cisco 7500 series and any other router may not
be able to switch traffic when dCEF is enabled on the Cisco 7500 series.
Conditions: This symptom is observed when LFI is enabled with one member link in the MLP
bundle.
