Features
station or PC. You can manage the switch stack by connecting to the console port or Ethernet
management port of any stack member. For more information about the CLI, see
Chapter 2, “Using
the Command-Line Interface.”
• SNMP—SNMP management applications such as CiscoWorks2000 LAN Management Suite (LMS)
and HP OpenView. You can manage from an SNMP-compatible management station or a PC that is
running platforms such as HP OpenView or SunNet Manager. The switch supports a comprehensive
set of MIB extensions and four remote monitoring (RMON) groups. For more information about
using SNMP, see
Chapter 33, “Configuring SNMP.”
•
Cisco IOS Configuration Engine (previously known to as the Cisco IOS CNS
agent)-—Configuration service automates the deployment and management of network devices and
services. You can automate initial configurations and configuration updates by generating
switch-specific configuration changes, sending them to the switch, executing the configuration
change, and logging the results.
• For more information about CNS, see Chapter 4, “Configuring Cisco IOS Configuration Engine.”
Manageability Features
•
Wired location service sends location and attachment tracking information for connected devices to
a Cisco Mobility Services Engine (MSE).
• 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
• DHCP server port-based address allocation for the preassignment of an IP address to a switch port
•
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
• Configurable MAC address scaling that allows disabling MAC address learning on a VLAN to limit
the size of the MAC address table
•
Disabling MAC address learning on a VLAN
• 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
•
CDP and LLDP enhancements for exchanging location information with video end points for
dynamic location-based content distribution from servers
