Chapter
Caveats in Cisco IOS XE 3.8S Releases
• CSCuc92350
Symptom: A connection between two copper SFPs does not become active.
Conditions: Occurs when two SFP interfaces are connected with one side set to 100 Mbps and the
other side set to negotiation auto.
Workaround: Set the speed to 10Mbps at both sides, then configure negotiation auto on one side
of the connection.
• CSCuc93895
Symptom: The router has an Automatic Protection Switching (APS) switchover time of more than
1 second.
Conditions: Occurs on MLPPP interfaces configured at a high scale when the router is running with
ICRM in SONET mode.
Workaround: There is no workaround.
• CSCuc93985
Symptom: The router initiates an Automatic Protection Switching (APS) switchover during a high
availability (HA) stateful switchover (SSO).
Conditions: Occurs during an HA SSO with single router APS (SR-APS).
Workaround: There is no workaround.
• CSCuc95716
Symptom: FPGA software for the OC-3 interface module is not bundled with the XE 3.8 image.
Conditions: Occurs when upgrading FPGA on the OC-3 interface module.
Workaround: Manually upgrade the OC-3 FPGA.
• CSCud01644
Symptom: The active forwarding processor (FP) is on the standby route switch processor (RSP).
Conditions: Occurs when you boot the two RSPs in quick succession and the FP on the standby RSP
becomes active before the FP on the active RSP.
Workaround: Reload the router.
• CSCud01908
Symptom: The show platform software object-manager fp active statistics command shows
pending objects on the Forwarding Manager (FMAN) on the forwarding processor (FP), indicating
a failure to download configurations from the Route Switch Processor (RSP) to the data plane (DP).
Conditions: Occurs when you apply a QoS shaping configuration at a high scale.
Workaround: There is no workaround.
• CSCud04407
Symptom: The router displays the following console error message:
Error - packet with
unsupported linktype 3
Conditions: Occurs when the router is passing traffic over the OC-3 interface module.
Workaround: There is no workaround.
• CSCud04529
Symptom: The router shows traffic loss.
