Impact

SR TE supports only upstream sampling for an ingress PE and downstream sampling for an egress PE. P device sampling is not supported.

None

In the case of downstream sampling for an ingress PE and upstream sampling for an egress PE, outbound interface information fails to be collected, or a sampling error occurs.

IPv4 private network routes and IPv6 private network routes support multi-PE load balancing. Route information is missing in the data sampled.

N/A

Route information is missing in the data sampled in multi-PE load balancing scenarios.

During the ISSU, NetStream flows are forcibly aged before the switchover, and new flows are established after the switchover. Therefore, NetStream does not take effect within a certain period of time.

N/A

Sampling flows are re-established during the ISSU, causing the NetStream function to be ineffective.

If the NetStream feature needs to be configured on a board, but the board does not support sampling data processing, you can configure a centralized sampling board that supports centralized service processing to process data.

Configure centralized sampling on a board that supports this function.

The function does not take effect.
