Loopback interfaces management for routing protocols administration
Private VLANs and local Proxy ARP help reduce broadcast with added security

Simplified VLAN configuration with industry-standard Access Ports for 802.1Q unaware endpoints and Trunk Ports for switch-to-switch links with Native VLAN
System defaults automatically set per-port broadcast, multicast, and unicast storm control for typical, robust protection against DoS attacks and faulty clients which can,
with BYOD, often create network and performance issues
IP Telephony administration is simplified with consistent Voice VLAN capabilities per the industry standards and automatic functions associated
