Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S
• CSCin64927
Symptoms: The xconnect command is not supported on Q-in-Q subinterfaces but the command-line
interface (CLI) parser does not prevent you from configuring this command on Q-in-Q
subinterfaces.
Conditions: This symptom is observed on platforms other than the Cisco 12000 series.
Workaround: There is no workaround.
• CSCin66535
Symptoms: On a Cisco 7500 series router, after a RPR, RPR-plus or SSO switchover, the router may
display the following message:
%RSP-3-RESTART: cbus complex
This will be followed by the reload of all VIPS in the router and the following message:
HA-2-NO_QUIESCE: Slot <slot#> did not quiesce, it will be disabled and then reloaded.
Conditions: This problem happens on a Cisco 7500 series router that is running Cisco IOS
Release 12.0 S and occurs after an RPR, RPR-plus, or SSO switchover. Similar symptoms can be
observed if the service single-slot-reload-enable command is not configured on the router, but in
this case, the cbus complex message will follow the “HA-2-NO_QUIESCE” error message.
Workaround: There is no workaround.
• CSCin66542
Symptoms: The line protocol on a T1 of a T3 controller in a PA-MC-2T3+ port adapter may stay in
the down state even when looped.
Conditions: This symptom is observed on a Cisco 7200 series and Cisco 7500 series.
Workaround: There is no workaround.
• CSCin70454
Symptoms: A PPP session may stay down after a long series of link flaps.
Conditions: This symptom is observed when MLP/LFI is enabled on an ATM PVC.
Workaround: There is no workaround.
• CSCin72219
Symptoms: If you enter the shutdown command followed by the no shutdown command on an
interface, traffic that congests the interface may cause the router to crash.
Conditions: This symptom is observed when a policy is attached to the interface.
Workaround: There is no workaround.
• CSCin73703
Symptoms: A router may crash when you enter the set fr-fecn-becn command.
Conditions: This symptom is observed when you enter the set fr-fecn-becn command for an
unsupported interface (that is, a non-Frame Relay interface).
Workaround: There is no workaround.
• CSCuk48013
Symptoms: A Cisco 7500 series router that is running 12.0S may drop traffic to a static route after
a microcode reload. The symptom may also occur in other releases.
Conditions: Traffic loss will occur for static routes to /32 prefixes that are attached to an interface,
that is, the ip route prefix mask interface-type interface-number command is enabled.
