Chapter
Caveats in Cisco IOS XE 3.8S Releases
Workaround: Reset the interface module.
• CSCuc91007
Symptom: A slave clock displays a high 1PPS offset value from the master clock.
Conditions: Occurs after an interface module reset or stateful switchover (SSO) on the master
device.
Workaround: There is no workaround.
• 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.
• CSCuc95590
Symptom: The router does not automatically upgrade the FPGA software.
Conditions: Occurs when you load a new image while running an older FPGA version.
Workaround: There is no workaround; however the issue has no functional impact.
• 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.
• CSCuc98185
Symptom: One out of 48 EFPs in a BDI does not receive traffic when running L3 multicast. The
issue does not happen consistently.
Conditions: Occurs under the following conditions:
– You configure Protocol-Independent Multicast-Sparse Mode (PIM-SM) with a static
rendezvous point (RP).
– You configure a bridge domain interface (BDI) on the PE2 access side
– You use the BDI to send IGMP v2 static join messages to a single multicast group
– You disable IGMP snooping globally.
– You configure 24 EFPs and map them to a single bridge-domain.
– You initiate multicast traffic.
