Cabletron Systems 2E43-51R Switch User Manual


 
Chapter 1:
Introduction
1-6 2E43-51/2E43-51R User’s Guide
The RAD requests start out at an interval of 1 second. The interval then
doubles after every transmission until an interval of 300 seconds is
reached. At this point, the interval remains at 300 seconds. The RAD
requests continue until an IP address is received from a BootP server, or
an IP address is entered using Local Management.
1.3.6 Management
Management of the 2E43-51 is accomplished using SNMP compliant
management tools for in-band Local Management. Out-of-band Local
Management is provided through the RJ45 COM port on the front panel
using a VT100 terminal or a VT100 terminal emulator. In-band remote
management is possible through any SNMP compliant Network
Management Software.
Local Management provides the ability to manage the 2E43-51 and any of
the optional Fast Ethernet Interface Modules installed in ports 5 and 6,
and the optional High Speed Interface Module (HSIM).
The associated HSIM user’s guide provides detailed information about
the HSIM Local Management.
1.3.7 Switching Options
The 2E43-51 provides 802.1D switching, 802.1Q switching or SecureFast
Switching Virtual Network Services between all of the front panel
interfaces including Fast Ethernet Interface Modules and High Speed
Interface Module (HSIM).
IEEE 802.1Q switching and SecureFast switching allow for future
migration to Virtual Network technologies without requiring the
replacement of existing equipment.
1.3.8 Standards Compatibility
The 2E43-51 provides IEEE 802.1D Spanning Tree Algorithm (STA)
support to enhance the overall reliability of the network and protect
against “loop” conditions. The 2E43-51 also supports 100BASE-TX and
100BASE-FX Fast Ethernet standards and a wide variety of industry
standard MIBs including RFC 1213 (MIB II), RFC 1757 (RMON),
RFC 1493 (Bridge MIB) and RFC 1354 (FIB MIB). A full suite of
Cabletron Systems Enterprise MIBs provide a wide array of statistical
information to enhance troubleshooting.
