Chapter 1 Overview
Software Features
Manageability Features
• 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.
