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
• 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 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
• Out-of-band management access through the Ethernet management port to a PC
• 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)
Note For additional descriptions of the management interfaces, see the “Network Configuration Examples”
section on page 1-16.
