[Usage Scenario]
ERSPAN is a Layer 3 remote mirroring technology that duplicates packets from specified ports. It sends the duplicated packets to a remote data monitoring device through a GRE tunnel, allowing users to analyze these packets using the monitoring device for network monitoring and troubleshooting.
[Notes]
To configure encapsulation parameters for Layer 3 remote mirroring, you only need to specify the mirror source and destination port on the source device. Additionally, all devices must have a unicast routing protocol configured, ensuring a seamless Layer 3 network between the devices.It should be noted that ERSPAN needs to be configured after the destination IP actually takes effect. For example, if the destination IP corresponds to a static ARP, then the static ARP needs to be configured first before configuring the ERSPAN function.
[Use Cases]
sonic# configuresonic(config)# mirror session 1 erspan direction rx src-ethernet 3 gre-src-ip 10.1.1.1 gre-dst-ip 30.1.1.2
