This feature supports VRFs/Layer 3 VSNs to operate in stealth mode by disabling ICMP responses on specific VRFs/Layer 3 VSNs.
If the ICMP response is disabled, the switch does not respond to any ICMP requests received on the VRFs/Layer 3 VSNs.
If the ICMP response is enabled, the switch responds to ICMP requests received on the VRF/Layer 3 VSNs.
