Wired location service sends location and attachment tracking information for connected devices to
a Cisco Mobility Services Engine (MSE).
CNS embedded agents for automating switch management, configuration storage, and delivery.
DHCP for automating configuration of switch information (such as IP address, default gateway,
hostname, and Domain Name System [DNS] and TFTP server names).
DHCP relay for forwarding User Datagram Protocol (UDP) broadcasts, including IP address
requests, from DHCP clients.
DHCP server for automatic assignment of IP addresses and other DHCP options to IP hosts.
DHCP server port-based address allocation for the preassignment of an IP address to a switch port.
DHCPv6 bulk-lease query for requesting information about DHCPv6 bindings.
DHCPv6 relay source configuration for configuring the source address for messages from the relay
agent.
DHCPv6 bulk-lease query to support new bulk lease query type (as defined in RFC5460).
The DHCPv6 relay source configuration feature to configure a source address for DHCPv6 relay
agent.
Directed unicast requests to a DNS server for identifying a switch through its IP address and its
corresponding hostname and to a TFTP server for administering software upgrades from a TFTP
server.
Address Resolution Protocol (ARP) for identifying a switch through its IP address and its
corresponding MAC address.
Unicast MAC address filtering to drop packets with specific source or destination MAC addresses.
Configurable MAC address scaling that allows disabling MAC address learning on a VLAN to limit
the size of the MAC address table.
Disabling MAC address learning on a VLAN.
Cisco Discovery Protocol (CDP) Versions 1 and 2 for network topology discovery and mapping
between the switch and other Cisco devices on the network.
Link Layer Discovery Protocol (LLDP) and LLDP Media Endpoint Discovery (LLDP-MED) for
interoperability with third-party IP phones.
Support for the LLDP-MED location TLV that provides location information from the switch to the
endpoint device.
CDP and LLDP enhancements for exchanging location information with video end points for
dynamic location-based content distribution from servers.
Network Time Protocol (NTP) version 4 for NTP time synchronization for both IPv4 and IPv6.
Network Time Protocol version 4 (NTPv4) to support both IPv4 and IPv6 and compatibility with
NTPv3.
Cisco IOS File System (IFS) for providing a single interface to all file systems that the switch uses.
Configuration logging to log and to view changes to the switch configuration.
Configuration replacement and rollback to replace the running configuration on a switch with any
saved Cisco IOS configuration file.
Unique device identifier to provide product identification information through a show inventory
user EXEC command display.
