How do I block a suspect mac-address on a customer edge router or switch? On Huawei exists a command that reminds me of the shun
option on Cisco ASA:
mac-address blackhole mac-address { vlan vlan-id | vsi vsi-name }
# Example:
#
mac-address blackhole 0050-56c0-fb47 vlan 1
#
#
Works both in VLAN and VPLS environment.
