Resolved Caveats—Cisco IOS Release 12.0(27)S2
• CSCee04454
Symptoms: A Cisco 10000 series router reloads unexpectedly as ATM VCs are coming up.
Conditions: This symptom is believed to occur only when ACLs are applied on ATM interfaces, and,
only rarely then, on images that contain the CSCed72686 fix.
Workaround: There is no workaround.
• CSCee05882
Symptoms: The queue size may not be set up correctly after a Cisco 10000
Conditions: This symptom is observed when an MLP bundle has an output policy attached to an
interface and the service policy contains WRED parameters.
Workaround: Remove and reattach the service policy to the MLP bundle interface after the router
has reloaded.
• CSCee07446
Symptoms: The ping mpls pseudowire and the trace mpls pseudowire commands may fail on a
Cisco 12000 series.
Conditions: This symptom is observed when you enter these commands for an Engine 3 line card.
Workaround: There is no workaround.
• 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.
• 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.
• 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.
