Manageability Features
These are the 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
• 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) and LLDP Media Endpoint Discovery (LLDP-MED) 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
• 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
• 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 (requires the cryptographic universal software
image)
• 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 universal software image)
• 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.
