The 3C16630 Management Module and 3C16632 Advanced RMON Module
are SNMP-conformant, slide-in modules that can manage an entire stack of units.
SmartAgent software in the Modules automatically gather and collate information
about the stack. As well as supporting in-band management via a network link,
each Module has a serial port which allows out-of-band management. When
installed, the
Modules allow you to:
- Monitor and change the configuration of all units in the stack.
- Set up resilient links. You can protect a critical communication link against
failure by ensuring that, should the main link fail, a standby link immediately
and automatically takes over.
- Implement security features. For example, each user is assigned an access
level that determines which management parameters the user can view or modify.
Also, end station access can be restricted to a particular port.
- Monitor network performance. The management facility maintains statistics that
assist you to monitor the operation of the network and perform predefined
actions automatically when thresholds are exceeded.
- Poll other devices on the network.
You can use one of several ways to access the management facility:
- Over the network, using an SNMP network manager, such as Transcend WorkGroup
Manager for Windows (3C15000 series). Each network manager provides its own user
interface to the management facilities.
Using SNMP management, for example, you can configure traps to be sent to the
management station if critical thresholds are exceeded. You can use SNMP running
over the IP or IPX protocols.
- By connecting a VT100 terminal (or workstation with terminal emulation
software) to the serial port on the Module. The terminal can be connected
directly or remotely, via a modem. The VT100 management interface, which is a
menu-driven user interface built into the Modules, is used. The VT100 management
interface provides a subset of the features of SNMP management.
- Over a TCP/IP network, using a workstation running VT100 terminal emulation
and Telnet. The VT100 management interface is used.
- By connecting a workstation running SLIP to the serial port, which allows you
to use out-of-band Telnet or SNMP management. The workstation can be connected
directly or remotely, via a modem. This method provides a way of managing the
stack in situations where the LAN is not providing a reliable service, or where
the network manager does not have direct LAN connectivity.
Any changes made to the configuration of a device using one method of access
will be reflected in the configuration seen by all other methods of access.
Using SNMP management, you can access RMON statistics for a stack. Adequate
statistics for most situations will be stored by the SuperStack II Hub 10
Management Module (3C16630A). If you want to perform extremely comprehensive
RMON analysis on heavily loaded networks, you should consider using the
SuperStack II Hub 10 Advanced RMON Module (3C16632).
There is no functional difference between the two types of module. All
software will work with both modules as described in this manual. See Appendix A
for the specification of each module.
Stacking Units
You can manage a stack containing a mixture of SuperStack II Hub 10 ,LinkBuilder
FMS, FMS II, 10BT and 10BTi units.A stack can consist of up to eight units
linked together with Hub expansion cables (3C625). A stack behaves as a single
Ethernet
repeater. Only one Management Module or Advanced RMON Module is needed to manage
the stack.
SuperStack II Hub 10 Management Module
The SuperStack II Hub 10 Management Module (3C16630A) can be installed in the
following units:
3C16665A SuperStack II Hub 10 6 Port Fiber
3C16670A SuperStack II Hub 10 12 Port TP
3C16671A SuperStack II Hub 10 24 Port TP
3C16672A SuperStack II Hub 10 24 Port Telco
This module can be installed in the earlier LinkBuilder FMS II units also.
SuperStack II Hub 10 Advanced RMON Module:
The SuperStack II Hub 10 Advanced RMON Module (3C16632) can be installed
wherever its companion module (3C16630A) may be used, including the earlier
LinkBuilder FMS II modules. See the list above.
The module supports comprehensive, highly accurate, advanced RMON statistics for
heavily loaded networks.
