CLI—The Cisco IOS software supports desktop- and multilayer-switching features. You can access 
the CLI either by connecting your management station directly to the switch console port or by using 
Telnet from a remote management station. For more information about the CLI, see 

SNMP—SNMP management applications such as CiscoWorks2000 LAN Management Suite (LMS) 
and HP OpenView. You can manage from an SNMP-compatible management station that is running 
platforms such as HP OpenView or SunNet Manager. The switch supports a comprehensive set of 
MIB extensions and four remote monitoring (RMON) groups. For more information about using 
SNMP, see 

Cisco IOS Configuration Engine (previously known to as the Cisco IOS CNS 
agent)-—Configuration service automates the deployment and management of network devices and 
services. You can automate initial configurations and configuration updates by generating 
switch-specific configuration changes, sending them to the switch, executing the configuration 
change, and logging the results. 

For more information about CNS, see 

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

Cisco IOS File System (IFS) for providing a single interface to all file systems that the switch uses
