Chapter
Caveats in Cisco IOS XE 3.8S Releases
–
With multicast traffic enabled, you configure 24 EFPs and map them to the existing
bridge-domain.
One of the 48 EFPs does not receive traffic.
Workaround: Reload the router.
• CSCud01641
Symptom: The standby RSP resets when you issue the write memory command on the active RSP.
Conditions: Occurs under the following conditions:
–
The BITS interface is configured as an input clock source.
–
Quality level-based clock selection is enabled.
Workaround: Disable QL-enabled mode for network-clock synchronization.
• 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.

Conditions: Occurs when you upgrade the FPGA software using an IOS image bundled with a new
FPGA version.
Workaround: Manually upgrade the FPGA software.
• CSCud08913
