Switch Management
This chapter explains the methods that you can use to
configure management access to the switch. It describes the
types of management applications and the communication
and management protocols that deliver data between your
management device (workstation or personal computer) and
the system. It also contains information about port connection
options.
This chapter covers the following topics:
• Management Access Overview
• Key Concepts
• Key Guidelines for Implementation
• Web Management Access
• Administration Console Access
• SNMP Access
• Standards, Protocols, and Related Reading
Management Access Overview
The switch gives you the flexibility to access and manage the
switch using any or all of the following methods.
The web browser interface and administration console (CLI)
support are embedded in the switch software and are
available for immediate use.
22 User’s Manual
Hardened Managed Ethernet Switch
Administration Console (CLI)
The administration console is an internal, character-oriented,
Command Line Interface (CLI) for performing system
administration such as displaying statistics or changing option
settings.
Using this method, you can view the administration console
from a terminal, personal computer, Apple Macintosh, or
workstation connected to the switch’s console port.
There are two ways to use this management method: direct
access or modem access. The following sections describe
these methods.
Direct Access
Direct access to the administration console is achieved by directly
connecting a terminal or a PC equipped with a terminal-emulation
program (such as HyperTerminal) to the switch console port.
When using the management method, configure the terminal-emulation
program to use the following parameters (you can change these settings
after login):
[DEFAULT PARAMETERS]
♦ 115,200bps
♦ 8 data bits
♦ No parity
♦ 1 stop bit
This management method is often preferred because you can remain
connected and monitor the system during system reboots. Also, certain
error messages are sent to the serial port, regardless of the interface
through which the associated action was initiated. A Macintosh or PC
attachment can use any terminal-emulation program for connecting to
the terminal serial port. A workstation attachment under UNIX can use
an emulator such as TIP.
User’s Manual 23
Hardened Managed Ethernet Switch
Modem Access
You can access the switch’s administration console from a PC or
Macintosh using an external modem attached to the console port. The
switch management program provides Console Port screen, accessible
from the Basic Management screen that lets you configure parameters
for modem access.
When you have configured the external modem from the administration
console, the switch transmits characters that you have entered as output
on the modem port. The switch echoes characters that it receives as
input on the modem port to the current administration console session.
The console appears to be directly connected to the external modem.
Web Management
The switch provides a browser interface that lets you
configure and manage the switch remotely.
After you set up your IP address for the switch, you can
access the switch’s web interface applications directly in your
web browser by entering the IP address of the switch. You
can then use your web browser to list and manage switch
configuration parameters from one central location, just as if
you were directly connected to the switch’s console port.
SNMP-Based Network Management
You can use an external SNMP-based application to
configure and manage the switch. This management method
requires the SNMP agent on the switch and the SNMP
Network Management Station to use the same community
string. This management method, in fact, uses two
community strings: the get community string and the set
community string. If the SNMP Network management station
only knows the set community string, it can read and write to
the MIBs. However, if it only knows the get community string,
it can only read MIBs. The default get and set community
strings for the switch are public.
24 User’s Manual
Hardened Managed Ethernet Switch
Protocols
The switch supports the following protocols:
VIRTUAL TERMINAL PROTOCOLS, SUCH AS TELNET
A virtual terminal protocol is a software program, such as Telnet, that allows
you to establish a management session from a Macintosh, a PC, or a UNIX
workstation. Because Telnet runs over TCP/IP, you must have at least one IP
address configured on the switch before you can establish access to it with a
virtual terminal protocol.
<Note> Terminal emulation is different from a virtual terminal protocol in that you
SIMPLE NETWORK MANAGEMENT PROTOCOL (SNMP)
SNMP is the standard management protocol for multivendor IP networks.
SNMP supports transaction-based queries that allow the protocol to format
messages and to transmit information between reporting devices and
data-collection programs. SNMP runs on top of the User Datagram Protocol
(UDP), offering a connectionless-mode service.
must connect a terminal directly to the console port.
Management Architecture
All of the management application modules use the same
Messaging Application Programming Interface (MAPI). By
unifying management methods with a single MAPI,
configuration parameters set using one method (e.g. console
port) are immediately displayed the other management
methods (e.g. SNMP agent of web browser).
The management architecture of the switch adheres to the
IEEE open standard. This compliance assures customers that
the switch is compatible with, and will interoperate with other
solutions that adhere to the same open standard.

Hardened Managed Ethernet Switch
SNMP & RMON Management
This chapter describes the switch’s Simple Network
Management Protocol (SNMP) and Remote Monitoring
(RMON) capabilities.
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 pre-defined 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 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.
SNMP Agent and MIB-2 (RFC 1213)
The SNMP Agent running on the switch manager CPU is
responsible for:
User’s Manual 27
Hardened Managed Ethernet Switch
- Retrieving MIB counters from various layers of software modules according
to the SNMP GET/GET NEXT frame messages.
- Setting MIB variables according to the SNMP SET frame message.
- Generating an SNMP TRAP frame message to the Network Management
Station if the threshold of a certain MIB counter is reached or if other trap
conditions (such as the following) are met:
WARM START
COLD START
LINK UP
LINK DOWN
AUTHENTICATION FAILURE
RISING ALARM
FALLING ALARM
TOPOLOGY ALARM
MIB-II defines a set of manageable objects in various layers
of the TCP/IP protocol suites. MIB-II covers all manageable
objects from layer 1 to layer 4, and, as a result, is the major
SNMP MIB supported by all vendors in the networking
industry. The switch supports a complete implementation of
SNMP Agent and MIB-II.
RMON MIB (RFC 2819) and Bridge MIB (RFC
1493)
The switch provides hardware-based RMON counters in the
switch chipset. The switch manager CPU polls these counters
periodically to collect the statistics in a format that complies
with the RMON MIB definition.
RMON Groups Supported
The switch supports the following RMON MIB groups defined in RFC 2819:
- RMON Statistics Group – maintains utilization and error statistics for the
switch port being monitored.
28 User’s Manual
Hardened Managed Ethernet Switch
- RMON History Group – gathers and stores periodic statistical samples from
the previous Statistics Group.
- RMON Alarm Group – allows a network administrator to define alarm
thresholds for any MIB variable. An alarm can be associated with Low
Threshold, High Threshold, or both. A trigger can trigger an alarm when the
value of a specific MIB variable exceeds a threshold, falls below a threshold,
or exceeds or falls below a threshold.
- RMON Event Group – allows a network administrator to define actions
based on alarms. SNMP Traps are generated when RMON Alarms are
triggered. The action taken in the Network Management Station depends
on the specific network management application.
Bridge Groups Supported
The switch supports the following four groups of Bridge MIB (RFC 1493):
- The dot1dBase Group – a mandatory group that contains the objects
applicable to all types of bridges.
- The dot1dStp Group – contains objects that denote the bridge’s state with
respect to the Spanning Tree Protocol. If a node does not implement the
Spanning Tree Protocol, this group will not be implemented. This group is
applicable to any transparent only, source route, or SRT bridge that
implements the Spanning Tree Protocol.
- The dot1dTp Group – contains objects that describe the entity’s transparent
bridging status. This group is applicable to transparent operation only and
SRT bridges.
- The dot1dStatic Group – contains objects that describe the entity’s
destination-address filtering status. This group is applicable to any type of
bridge which performs destination-address filtering.
