Chapter 1 Overview
• 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 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
•
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 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
• 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)
Configuration replacement and rollback to replace the running configuration on a switch with any
•
saved Cisco IOS configuration file
