and priority queuing for egress traffic

Configuration replacement and rollback to replace the running configuration on a switch with any 
saved Cisco IOS configuration file

Dynamic voice virtual LAN (VLAN) for multidomain authentication (MDA) to allow a dynamic 
voice VLAN on an MDA-enabled port

Embedded event manager (EEM) for device and system management to monitor key system events 
and then act on them though a policy (IP service image only)

Internet Group Management Protocol (IGMP) Helper to allow the switch to forward a host request 
to join a multicast stream to a specific IP destination address

IP Service Level Agreements (IP SLAs) support to measure network performance by using active 
traffic monitoring

IP SLAs EOT to use the output from IP SLAs tracking operations triggered by an action such as
