Netflow-Lite - Cisco Catalyst 4500 Series Software Configuration Manual

Chapter 1 Product Overview

NetFlow-lite

NetFlow-lite is only supported on the Catalyst 4948E and Catalyst 4948E-F Ethernet switches.
Note
The NetFlow-lite feature is based on ingress packet sampling at a monitoring point that can be an
interface on the switch. By exporting NetFlow sampled packets, it provides visibility into traffic that is
switched through the device. The rate at which input packets are sampled is configurable and a wide
range of sampling rates are supported. Each sampled packet is exported as a separate NetFlow data
record in the data path. NetFlow V9 and V10(IPFIX) export formats are supported.

Power over Ethernet
Power over Ethernet (PoE) allows the LAN switching infrastructure to provide power to an endpoint
("powered device") over a copper Ethernet cable. This capability, once referred to as "inline power," was
originally developed by Cisco in 2000 to support emerging IP telephony deployments.
IP telephones need power for operation, and Power over Ethernet supports scalable, manageable power
delivery and simplifies IP telephony deployments. As wireless networking emerged, Power over
Ethernet began powering wireless devices in locations where local power access did not exist.

Secure Shell
Secure Shell (SSH) is a program that enables you to log into another computer over a network, to execute
commands remotely, and to move files from one machine to another. The switch may not initiate SSH
connections: SSH will be limited to providing a remote login session to the switch and will only function
as a server.
Simple Network Management Protocol
Simple Network Management Protocol (SNMP) facilitates the exchange of management information
between network devices. The Catalyst 4500 series switch supports these SNMP types and
enhancements:
•
•

SNMP—A full Internet standard
SNMP v2—Community-based administrative framework for version 2 of SNMP
SNMP v3—Security framework with three levels: noAuthNoPriv, authNoPriv, and authPriv
(available only on a crypto image, such as cat4000-i5k91s-mz)
SNMP trap message enhancements—Additional information with certain SNMP trap messages,
including spanning-tree topology change notifications and configuration change notifications
