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.

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.

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.

SIMPLE NETWORK MANAGEMENT PROTOCOL (SNMP)
SNMP is the standard management protocol for multivendor IP networks.

messages and to transmit information between reporting devices and
data-collection programs. SNMP runs on top of the User Datagram Protocol

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.

(RMON) capabilities.
Overview
RMON is an abbreviation for the Remote Monitoring MIB
(Management Information Base).
by the Internet Engineering Task
1757, 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.

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 1757) 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 1757:
- RMON Statistics Group – maintains utilization and error statistics for the switch port being monitored.

Black Box Hardened Managed Ethernet Switch
- RMON History Group – gathers and stores tical samples from
the previous Statistics Group.
- RMON Alarm Group – allow
thresholds for any MIB variable.
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.
