Resolved Caveats—Cisco IOS Release 12.0(28)S3
Workaround: Enter the shutdown interface configuration command followed by the no shutdown
interface configuration command on the multilink interface of the Cisco 7500 series.
• CSCin88303
Symptoms: The line protocol of unchannelized interfaces on a PA-MC-2T3+ port adaptor remains
down although the link is up.
Conditions: This is observed when you change from the channelized mode to the unchannelized
mode by entering the no channelized command on the T3 controller of the PA-MC-2T3+ port
adaptor.
Workaround: There is no workaround.
• CSCin88356
Symptoms: The output of the show interfaces serial number command does not show the total
output packet drops.
Conditions: This symptom is observed when you apply a service policy on an interface that is
configured for CEF.
Workaround: Enter the show policy map interface interface-name command to see the total output
packet drops.
• CSCin88417
Symptoms: Transmit accumulator loss may occur for MLP interfaces after you have performed an
OIR of a VIP. When the transmit accumulator value goes to zero, MLP may stop forwarding or
packets may be switched by dCEF.
Conditions: This symptom is observed after you have performed an OIR of a VIP while traffic is
running on MLP bundles.
Workaround: Reload the VIP again and ensure that no traffic leaves from the MLP bundles
immediately after the VIP comes up.
• CSCin89330
Symptoms: Distributed MFR does not function, that is, a ping on a distributed MFR interface fails.
Conditions: This symptom is observed on a Cisco 7500 series that has a distributed MFR interface.
Workaround: There is no workaround.
• CSCsa41907
Symptoms: When a channel group is removed from and added to a controller and when a PRE
switchover occurs, the line protocol on another channel goes down after a while and input packets
are not counted.
Conditions: This symptom is observed on a Cisco 10000 series that is configured with 6-port
channelized T3 line card.
Workaround: Enter the shutdown interface configuration command followed by the no shutdown
interface configuration command on the affected interface.
Alternate Workaround: Ensure that the you enter the hw-module standby-cpu reset command
before a PRE switchover occurs.
• CSCsa42857
Symptoms: A duplex configuration (half/full) is not saved to NVRAM. This situation causes the
default configuration (half duplex) to be used after the router reloads.
Conditions: This symptom is observed on a PA-2FE port adapter that is installed in a Cisco 7200
series that runs Cisco IOS Release 12.0(28)S1.
