Cisco IOS XE 3S Release Notes for the Cisco ASR 903 Router
OL-26630-08
Caveats in Cisco IOS XE 3.9S Releases
• CSCuc92953
Symptom: The RSP crashes.
Conditions: Occurs under the following conditions:
– You configure Protocol-Independent Multicast-Sparse Mode (PIM-SM) with a static
rendezvous point (RP).
– You create an EVC port channel on the access side with one member link
– You create bridge domain interfaces (BDIs) with 1:1 mapping between EVCs and
bridge-domains.
– You use the BDIs to send IGMP v2 static join messages to a single multicast group
– On the remote device, you create 150 EFPs and map them to the BDIs.
– You initiate multicast traffic.
– You set the EFPs to the default configuration and add them to the existing port-channel
The router crashes.
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.
• CSCud01855
Symptoms: APS switchover may occasionally lead to inconsistent/incorrect APS states with CEM
config.
Conditions: Seen when APS is configured with CEM/ATM on IM-4OS on ASR903. Caused due to
notifications not being correctly sent to CEM subsystem.
Workaround: No workaround.
• CSCud01908
Symptom: Debug commands show 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: Delete the QoS policies and remove the QoS configuration from the interface.
• 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.
