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
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
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) 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) for providing a consistent time stamp to all switches from an external
source
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
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
In-band management access for up to 16 simultaneous Telnet connections for multiple CLI-based
sessions over the network
In-band management access for up to five simultaneous, encrypted Secure Shell (SSH) connections
for multiple CLI-based sessions over the network (requires the cryptographic version of the
software)
In-band management access through SNMP Versions 1, 2c, and 3 get and set requests
Out-of-band management access through the switch console port to a directly attached terminal or
to a remote terminal through a serial connection or a modem
Secure Copy Protocol (SCP) feature to provide a secure and authenticated method for copying
switch configuration or switch image files (requires the cryptographic version of the software)
DHCP Snooping enhancement to support the selection of a fixed string-based format for the
circuit-id sub-option of the Option 82 DHCP field
