Chapter 5: Web-Based Browser Management
5. Web-Based Browser Management
The Hardened Ethernet Extender Switch provides a Web-based browser interface
for configuring and managing the Hardened Ethernet Extender Switch. This
interface allows you to access the Hardened Ethernet Extender Switch using a
preferred Web browser.
This chapter describes how to configure the Hardened Ethernet Extender Switch
using its Web-based browser interface.
5.1 SNMP and RMON Management
This chapter describes the Hardened Ethernet Extender SNMP and RMON
capabilities.
5.1.1 Overview
RMON is an abbreviation for the Remote Monitoring MIB (Management
Information Base). RMON is a system defined by the Internet Engineering Task
Force (IETF) Document RFC 2819, which defines how networks can be monitored
remotely.
RMONs typically consist of two components: an RMON probe and a management
workstation:
• The RMON probe is an intelligent device or software agent that continually
collects statistics about a LAN segment or VLAN. The RMON probe transfers the
collected data to a management workstation on request or when a predefined
threshold is reached.
• The management workstation collects the statistics that the RMON probe
gathers. The workstation can reside on the same network as the probe, or it
can have an in-band or out-of-band connection to the probe.
The Hardened Ethernet Extender Switch provides RMON capabilities that allow
network administrators to set parameters and view statistical counters defined in
MIB-II, Bridge MIB, and RMON MIB. RMON activities are performed at a Network
Management Station running an SNMP network management application with
graphical user interface.
5.1.2 SNMP Agent and MIB-2 (RFC 1213)
The SNMP Agent running on the Hardened Ethernet Extender Switch manager
CPU is responsible for:
• Retrieving MIB counters from various layers of software modules according to
the SNMP GET/GET NEXT frame messages.
