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)
