Rate limiting of mirrored traffic provides support to control the rate of mirrored traffic that can egress the switch. This feature can be applied to both regular port mirroring and encapsulated mirroring (e.g., mirroring to GRE tunnel), depending on the platform.

This feature enables policer (using policy-map) on a VTEP to rate limit traffic per VLAN/VNI. The policer can be applied in both input and output directions to rate limit decapsulated and encapsulated VXLAN traffic, respectively. Prior to EOS-4.32.0F, the policers are not applicable on multicast traffic through the VTEP. For platforms supporting rate limiting of both bridged and routed encapsulated traffic, the rate limiting would be done on common policer limits.
