8 Product Overview
ELS100-24TXM
Configuration and Management Interfaces
The ELS100-24TXM switch can be managed using any of the following
three methods:
•
Serial console, out-of-band
An RS-232 connection, using a DB-9 connector, is supported for out-
of-band switch management. Serial console management is per-
formed using a terminal, or computer system running communica-
tions software. See Chapter 3, “ELS100-24TXM User Interface,” for
more detailed information on managing the ELS100-24TXM switch
via the serial console.
•
Telnet, in-band (over Ethernet)
The switch supports management through a Telnet connection using
the TCP/IP protocols. Telnet is performed using an ASCII terminal or
computer system running communications software. See Chapter 3,
“ELS100-24TXM User Interface,” for more detailed information on
managing the switch via the serial console. Global password protec-
tion for changing the operating parameters of the switch is provided.
•
SNMP-based network manager, in-band
The switch can be managed using SNMP, the most common protocol
used today for network management. Standard agent MIBs embed-
ded in the switch provide basic SNMP management through indus-
try-standard SNMP applications.
Management security protection is provided based on SNMP com-
munity names. See Chapter 5, “SNMP Management,” for more infor-
mation.
RMON
RMON (Remote Monitoring) is a facility used to manage networks
remotely while providing multi-vendor interoperability between monitoring
devices and management stations. RMON is defined by an SNMP MIB.
This MIB is divided into nine different groups, each gathering specific
statistical information or performing a specific function. RMON-capable
devices gather network traffic data and then store them locally until
downloaded to an SNMP management station.
The ELS100-24TXM supports four of the nine groups of RMON defined
for Ethernet networks on a per port basis. Specifically, these are:
•
Statistics: a function that maintains counts of network traffic statistics
such as number of packets, broadcasts, collisions, errors, and
distribution of packet sizes.
•
History: a function which collects historical statistics based on user-
defined sampling intervals. The statistical information collected is the
same as the Statistics group, except on a time stamped basis.
•
Alarm: a function that allows managers to set alarm thresholds based
on traffic statistics. Alarms trigger other actions through the Event
group.
