Open issues

Table 1.           Open issues for Cisco NCS 560 Series Routers, Release 25.1.2

Bug ID

Description

CSCwp09786

BFD flaps occur consistently after shutting or unshutting a bundle interface

Known issues

●   Telemetry data collection may timeout due to CPU overload during route churn. In such scenarios, telemetry will resume when the CPU becomes available after the route churn is complete.

●   The standby RP may get into 'NOT READY' state intermittently due to some network churn, though the corresponding VM is up and running. But this is a transient state and shows that some data aren’t in sync between active and standby due to the network churn. After both active and standby are in sync with respect to all the parameters, then the standby RP comes into 'READY' state.
