Security feature that   restricts the client IP traffic to those source IP addresses configured in   the DHCP binding table

Dynamic ARP Inspection (DAI)

Security feature that   determines validity of an ARP packet based on valid MAC address to IP address   bindings stored in DHCP binding table

Syslog event for vMotion

A unique Syslog message from the VSM indicating a vMotion event and the migrated VM.

IPv6 Management

Support for IPv6 through the management address for Telnet/SSH access into the VSM. IPv6 SNMP access will come in a future   release.

Virtual Service Domains (VSD)

Port Profile integrated   feature to ease deployment and association of L4-7 service virtual appliance solutions to specific VM VNICs
