FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs to deliver top-rated protection and high performance, including encrypted traffic.
Article The virtual MAC address is determined based on following formula on virtual cluster 1: 00-09-0f-09-<group-id_hex>-<vcluster_integer><idx> For example when there is group ID of 0 (default) in the mgmt1 in phy_index= 0, itf_name= mgmt1, mac=e0.23.ff.a0.98.04, vmac=00.09.0f.09.00(group ID is 0).00(vcluster_interger for vcluster 1 is 0 and index of the interface is 0)
If the same interface is change to virtual cluster 2, the mac address should add 8 on the second last digit, i.e., add 80 in hexadecimal:
add 80 in hexadecimal: 00 -> 80
Therefore it is necessary to follow virtual mac address: 00.09.0f.09.00.80
