Step 6
In the MAC Security area, do the following to determine whether the server can use different MAC addresses
when sending packets to the fabric interconnect:
a) Click the Expand icon to expand the area and display the radio buttons.
b) Click one of the following radio buttons to determine whether forged MAC addresses are allowed or
denied when packets are sent from the server to the fabric interconnect:
• Allow— All server packets are accepted by the fabric interconnect, regardless of the MAC address
associated with the packets.
• Deny— After the first packet has been sent to the fabric interconnect, all other packets must use the
same MAC address or they will be silently rejected by the fabric interconnect. In effect, this option
enables port security for the associated vNIC.
If you plan to install VMware ESX on the associated server, you must configure the MAC Security to
allow for the network control policy applied to the default vNIC. If you do not configure MAC Security
for allow, the ESX installation may fail because the MAC security permits only one MAC address while
the installation process requires more than one MAC address.
