Chapter 1 Configuration Overview
Feature Software Licensing
Industrial Application
• CIP—Common Industrial Protocol (CIP) is a peer-to-peer application protocol that provides
application level connections between the switch and industrial devices such as I/O controllers,
sensors, relays, and so forth.You can manage the switch using CIP-based management tools, su ch
as RSLogix. For more information about the CIP commands that the switch supports, see the
command reference.
• Profinet Version 2—Support for PROFINET IO, a modular communication framework for
distributed automation applications. The switch provides a PROFINET management conn ection to
the I/O controllers.
Manageability Features
• CNS embedded agents for automating switch management, configuration storage, and delivery.
• DHCP for automating configuration of switch information (suc h as IP address, default gateway,
hostname, and Domain Name System [DNS] and TFTP server names).
• DHCP relay for forwarding User Datagram Protocol (UDP) broa dcasts, including IP address
requests, from DHCP clients.
• DHCP server for automatic assignment of IP addresses and other DHCP options to IP hosts.
• DHCP-based autoconfiguration and image update to download a s pecified configuration of a new
image to a large number of switches.
• DHCPv6 bulk-lease query to support new bulk lease query type (as defined in RFC5460).
• DHCPv6 Relay Source Configuration feature to configure a source address f or DHCPv6 relay agent.
• DHCP server port-based address allocation for the preassignment of an IP address to a switch port.
• 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.
• 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.
• LLDP media extensions (LLDP-MED) location TLV that provides location information from the
switch to the endpoint device.
• Network Time Protocol (NTP) for providing a consistent time stamp to all switches from an external
source.
• Network Time Protocol version 4 (NTPv4) to support both IPv4 and IPv6 and compatibility with
NTPv3.
• Precision Time Protocol (PTP) as defined in the IEEE 1588 standard to synchr onize with
nanosecond accuracy the real-time clocks of the devices in a network.
