Local mirroring is supported on all 7210 SAS platforms as described in this document, including those operating in access-uplink mode.
Remote mirroring is supported on all 7210 SAS platforms as described in this document, except those operating in access-uplink mode.
The 7210 SAS-Mxp does not support the use of segment routing tunnels for remote mirroring.
The 7210 SAS devices allows multiple concurrent mirroring sessions so traffic from more than one ingress mirror source can be mirrored to the same or different mirror destinations. For more information, see the Configuration notes.
Remote mirroring uses a service distribution path (SDP) which acts as a logical way of directing traffic from one router to another through a unidirectional (one-way) service tunnel. The SDP terminates at the far-end router which directs packets to the correct destination on that device.
The SDP configuration from the mirrored device to a far-end router requires a return path SDP from the far-end router back to the mirrored router. Each device must have an SDP defined for every remote router to which it provides mirroring services. SDPs must be created first, before services can be configured.
