Resolved Caveats—Cisco IOS Release 12.0(27)S5
Workaround: There is no workaround. Note that the symptom does not occur when SSO is
configured because the MLP state is maintained.
• CSCin88273
Symptoms: After an RPR+ or SSO switchover occurs, an MLP sequence number mismatch may
occur, a ping between back-to-back interfaces may not go through, and the routing protocol through
this link may go down.
Conditions: This symptom is observed on a Cisco 7500 series that is configured for dMLP and RPR+
or SSO.
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.
• 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.
• CSCsa46887
Symptoms: A router builds an Echo Reply that is invalid and may be misunderstood.
Conditions: This symptom is observed on a router that is configured for LSPV when the router
receives an Echo Request with a Pad TLV that has a value of "Copy Pad TLV to reply." The Echo
Reply that the router builds includes residual data from previously received packets instead of the
pad pattern that was received.
Workaround: There is no workaround.
