Description (partial)


It is not a problem that the UDP Source Port of RP0 and RP1 do not match.
The only problem is that packets from both Act/Stb RPs are sent.

When netflow packets are output from both RPs, the traffic is doubled on the external collector side.

This problem occurs only when the netflow function is used in NCS560 with RSP redundancy.

There is no recovery.
