16 Introduction
System Features
sFlow
sFlow is the standard for monitoring high-speed switched and routed networks. sFlow technology is built
into network equipment and gives complete visibility into network activity, enabling effective
management and control of network resources.
CDP Interoperability
Allows the PowerConnect switch to interoperate with Cisco™ devices running CDP.
Industry Standard Discovery Protocol (ISDP) is a proprietary Layer 2 network protocol which inter-
operates with Cisco network equipment and is used to share information between neighboring devices
(routers, bridges, access servers, and switches).
Auto Config
Auto Config is a software feature which provides for the configuration of a switch automatically when
the device is initialized and no configuration file is found on the switch. Auto Config is accomplished in
three phases:
1.
Configuration or assignment of an IP address for the device
2.
Assignment of a TFTP server
3.
Obtaining a configuration file for the device from the TFTP server
Captive Portal
Blocks clients from accessing the network until user verification has been established. Verification can be
configured to allow access for both guest and authenticated users. Authenticated users must be validated
against a database of authorized Captive Portal users before access is granted.
SNMP Alarms and Trap Logs
The system logs events with severity codes and timestamps. The events are sent as SNMP traps to a trap
recipient list.
For information about SNMP Alarms and Traps, see "Defining SNTP Global Parameters."
Web Based Management
You can manage the system from any web browser. The switch contains an embedded web server that
serves HTML pages you can use to monitor and configure the system.
Configuration File Download
The switch’s configuration file includes both system-wide and port-specific device configuration data.
You can display configuration files through command-line interface (CLI) commands.
For information about downloading configuration files, see "Downloading Files."
