Chapter 1 Overview
Features
• 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
• 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
• 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

• Secure Copy Protocol (SCP) feature to provide a secure and authenticated method for copying
switch configuration or switch image files
• DHCP-based autoconfiguration and image update to download a specified configuration a new
image to a large number of switches
• Source Specific Multicast (SSM) mapping for multicast applications to provide a mapping of source
to allowing IGMPv2 clients to utilize SSM, allowing listeners to connect to multicast sources
dynamically and reducing dependencies on the application
• The HTTP client in Cisco IOS supports can send requests to both IPv4 and IPv6 HTTP servers, and
the HTTP server in Cisco IOS can service HTTP requests from both IPv4 and IPv6 HTTP clients
• Simple Network and Management Protocol (SNMP) can be configured over IPv6 transport so that
an IPv6 host can send SNMP queries and receive SNMP notifications from a device running IPv6.
• IPv6 supports stateless autoconfiguration to manage link, subnet, and site addressing changes, such
as management of host and mobile IP addresses
• Local web authentication banner so that custom banner or image file can be displayed at a web
authentication login screen
• CPU utilization threshold trap monitors CPU utilization
• LLDP-MED network-policy profile time, length, value (TLV) for creating a profile for voice and
voice-signalling by specifying the values for VLAN, class of service (CoS), differentiated services
code point (DSCP), and tagging mode
• Support for including a hostname in the option 12 field of DHCPDISCOVER packets. This provides
identical configuration files to be sent by using the DHCP protocol
• 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
• Increased support for LLPD-MED by allowing the switch to grant power to the power device (PD),
based on the power policy TLV request
• Cisco EnergyWise to manage the power usage of EnergyWise entities, such as power over Ethernet
(PoE) devices and end points running daemons.
• USB mini-Type B console port in addition to the standard RJ-45 console port. Console input is
