Chapter 1 Overview
Features
Manageability Features
•
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-based autoconfiguration and image update to download a specified configuration a new
image to a large number of switches
•
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
•
Precision Time Protocol (PTP) as defined in the IEEE 1588 standard to synchronize with
nanosecond accuracy the real-time clocks of the devices in a network
•
Cisco IOS File System (IFS) for providing a single interface to all file systems that the switch uses
•
Support for the SSM PIM protocol to optimize multicast applications, such as video
•
Source Specific Multicast (SSM) mapping for multicast applications provides a mapping of source
to group, allowing listeners to connect to multicast sources dynamically and reduces dependencies
on the application
•
Support for Enhanced Interior Gateway Routing Protocol (EIGRP) IPv6 to utilize IPv6 transport,
communicate with IPv6 peers, and advertise IPv6 routes
•
Support for these IP services, making them VRF aware so that they can operate on multiple routing
instances: HSRP, GLBP, uRPF, ARP, SNMP, IP SLA, TFTP, FTP, syslog, traceroute, and ping
•
Configuration logging to log and to view changes to the switch configuration
•
Unique device identifier to provide product identification information through a
show inventory
user EXEC command display
•
In-band management access through the device manager over a Netscape Navigator or Microsoft
Internet Explorer browser session
