The 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C do not support the use of segment routing tunnels for remote mirroring.
Mirrored frames can be copied and sent to a specific local destination or service on the router (local mirroring) or copies can be encapsulated and sent to a different router (remote mirroring). This functionality allows network operators to centralize not only sniffer resources, but also the technical staff who operate them.
The router 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 Configuration guidelines.
Remote mirroring uses an SDP that acts as a logical way of directing traffic from one router to another through a uni-directional (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. You must create SDPs before you can configure services.
