60.4 RSPAN Troubleshooting
Due to the following reasons, RSPAN may not function:
Whether the destination mirror port is a member of the Port-channel group. If so, please change the
Port-channel group configuration;
The throughput the destination port is less than the total throughput of the source mirror ports. If so, the
destination cannot catch all the datagrams from every source ports. To solve the problem, please reduce
the number of the source ports, or mirror only single direction data flow, or choose some other port with
higher capacity as the destination port.
Between the source switch and the intermediate switch, whether the native VLAN of the TRUNK ports is
configured as RSPAN VLAN. If so, please change the native VLAN for the TRUNK ports.
